16 Flaws in the Making of Ceramic Coffee Mugs

Xin xiang ceramic mug manufacturer, for customised ceramic coffee mugs, we usually go through professional ceramic mug factories. However, some customised ceramic mugs have problems, if the buyer can understand some of the reasons for the defects of the ceramic mugs, then the communication between the two sides will be more convenient and accurate.

1. Deformation

The shape of the ceramic mug presents a shape that does not conform to the specified design.

2.Falling slag

Ceramic mug glaze inside the cinder, mostly ceramic coffee mugs in the glaze into the kiln, adsorption of cinder. After firing, the grey residue is combined with the glaze, and there are obvious bumps and sharp edges when touched by hand.

3. Pores

Ceramic mug glaze appeared small holes, similar in shape to a pinhole. Ceramic cup pores formation reasons:

3.1. Ceramic mug in the firing process there are carbon particles deposited in the glaze, in the high temperature firing, carbon particles are burned off, the glaze will leave a dent, this and the difference between falling slag is: carbon particles of small particles, burned out in the firing process.

3.2. The surface quality of the blank is not good, the glaze Viscosity is too high, poor fluidity, can not make up for the defects on the surface of the blank, resulting in pinholes.

3.3. Too fast heating during firing, the glaze is not fully fused will also cause the phenomenon of pores.

4.Spot

Coloured stains appearing on the surface of ceramic mugs, which also become black spots.

5. Colour dirty

Ceramic mugs appear on the surface of the phenomenon of miscellaneous colours that should not be there.

6. Bumps

Ceramic mug body with the hand can feel the obvious bumps, bumps part of the corners of the rounded, smooth surface. This situation is mainly billet in the production process left behind by the residual mud.

7. Billet bubble

Ceramic mugs appear under the glaze hollow bubble. This is the glaze or the air in the middle of the blank in the firing process, was sealed inside the glaze caused.

8. Mud slag at the bottom of the mug

Ceramic mugs have tiny slag particles sticking to the bottom of the cup. Ceramic mugs have a link in the production process, grinding the bottom. Grinding in order to remove the bottom of the mug slag. Caused by the ceramic mug slag is mostly: grinding the bottom is incomplete or blank in the drying, glazing process stained slag.

9. lack of glaze

Ceramic mug lack of glaze. This situation occurs in the handle and cup body connection, the bottom of the cup, the mouth of the mug. Appearance of the lack of glaze is mostly in the glaze process operation is not in place, the glaze viscosity is too high, caused by.

10. Cracks

Ceramic mugs appear cracked. The main reasons for this situation:

10.1. Drying too fast: blanks in the drying process if the speed is too fast, it will lead to the internal and external shrinkage of the blank is not consistent, resulting in cracks.

10.2. Uneven glazing: ceramic mugs in the glazing process, the glaze thickness varies too much, which will cause uneven humidity of the blank, which will produce cracks in the firing process.

10.3. Secondary water absorption: after the blank is dried, because of the climate or the weather, causing the dried blank to absorb water twice. This causes inconsistency in the water content inside and outside the blank, which will produce cracks.

10.4. Temperature difference is too large: this situation is likely to occur in the winter in northern China ceramic factory, winter temperature is low, the blank in the firing process, the need to elongate the heating process, otherwise, it will be because the blank temperature is too low, warming up too quickly, resulting in ceramic mug cracks.

11. Baked flowers sticky glaze

Ceramic mug baking flower sticky glaze.

12. lack of clay

Ceramic mug blank mutilated phenomenon, mostly in the billet system during the production process or move in the process of bumping caused.

13. Glaze scratches

Ceramic mug picture appears stripes or points of dark wounds. This situation is mostly ceramic cups in the movement or transport is caused by external bumps.

14. Smoke

Ceramic mugs appear on the body of the grey-black or brown, such as the shape of the smoke marks. Smoke phenomenon, mostly in the firing process caused by improper operation. Specific references, ceramic mug firing technology.

15. Raw firing

Ceramic mugs do not reach the firing temperature, because the water content of ceramic mugs is too high, or improper control of kiln temperature and time, and caused. After raw firing, the colour of the mug is dark, the glaze is glossy and rough, and the sound is not brittle when it is knocked.

16. Over-fired

Ceramic mug firing temperature is too high, or too long. This situation will cause the ceramic mug deformation, size inconsistency, glaze blistering or glaze flow.

To sum up, these are 16 common defects of ceramic mugs. These ceramic coffee mugs often appear defects, as well as the causes of defects. After we understand them, we can be able to control the quality of ceramic mugs easily. This will also make it easier to pick the right ceramic mug factory.

Factors to Consider for Custom Ceramic Coffee Mugs

Xinxiang ceramic mug manufacturer, ceramic coffee mugs are a kind of daily drinking utensils. Ceramic coffee mugs can be divided into many types according to raw materials, glaze, flower paper, firing, capacity, shape and colour. So, what factors should we consider when we want to customise a ceramic coffee mug? If you want to find a more suitable ceramic coffee mug for yourself, then you should understand the difference between the various factors of ceramic coffee mugs. For example, the raw materials of ceramic mugs: stoneware, ceramic, bone china and rough pottery. The flower paper and firing of the ceramic mug: low, medium and high temperature. It also affects whether this ceramic mug is dishwasher and microwave safe.

1. Raw material of ceramic mugs

The raw material for ceramic mugs is china clay. The composition of china clay is mainly kaolin, and contains feldspar, quartzite and mullite components. Knead the clay into a ceramic mug - billet.

2. Ceramic mug glaze

Glaze is attached to the surface of the ceramic blank a continuous vitreous layer, or a mixture of vitreous and crystalline layer. Modern ceramic mug production glaze is divided into lime glaze and long ancient glaze. Lime glaze is used to glaze fruit (similar to porcelain stone of a natural mineral raw materials) and grey glaze (the main ingredient of calcium oxide) formulated, feldspar glaze is mainly composed of quartz, feldspar, marble, kaolin and so on. In the lime glaze and feldspar glaze to add metal oxides, or infiltration of other chemical ingredients, it will become a variety of glaze colours.

The general thickness of the glaze is only 1-3% of the thickness of the blank, but after kiln firing, it is tightly adhered to the porcelain tyre, so that the porcelain densification, soft luster and impermeable to water and gas, giving a person the feeling of bright as a mirror. At the same time can improve the use of strength, to prevent pollution, easy to clean and so on.

There are many kinds of ceramic glaze, according to the billet class points, there are porcelain glaze, pottery glaze and flintware glaze; according to the firing temperature points, 1100 ° C below the glaze is known as low-temperature glaze, 1100 ° C-1250 ° C between the glaze fired into the glaze for the medium-temperature glaze, 1250 ° C above the glaze fired into the glaze for high-temperature glaze; glaze features classified by white glaze is probably out of the love of the silverware, the colour of the glaze is colourful with its colourful by the people! Welcome, crystalline glaze pattern variation beautiful and moving, kiln-variable pattern glaze dazzling, beautiful, crackle glaze clear and simple, elegant and chic. In addition to the above, there are no light glaze, milky glaze, salt glaze and so on.

3. Ceramic mug flower paper

Ceramic flower paper is the carrier of ceramic ink, divided into ceramic glaze decal paper and ceramic glaze under the glaze decal paper, flower paper types due to the composition of the difference.

Water shift decal paper the most basic material is a small film backing paper, it is a particularly strong water absorption, the surface is coated with a water-soluble adhesive film paper, printed flower paper soaked in water, the paper absorbs water, dissolve the surface of the water-soluble adhesive, you can make the pattern of the oil agent by the surface of the paper sliding separation, the separation of the pattern is also with a small amount of water-soluble adhesive, you can stick it on the porcelain pieces, as the name suggests, known as the water shift decal.

High-temperature paper firing temperature, generally controlled at 600 ℃ - 1000 ℃. According to the position of the glaze where the flower paper, set a different firing temperature. This firing temperature is much higher than the low temperature flower paper. Therefore, ceramic coffee mugs with high temperature floral paper are not afraid of high temperature. The firing temperature of low-temperature flower paper is around 150℃. Therefore, it can be seen that the ceramic coffee mug with low temperature flower paper is not adaptable to high temperature. If it is put into the microwave oven and heated at a high temperature, the colour of its pattern will fade or even disappear. The evaporation of the ink of the flower paper is not good for the health of our body.

4. Ceramic mug firing

Ceramic mugs can actually be divided into three kinds in the firing process. One is a single firing. That is, from the blank mud to our commonly used ceramic coffee mugs, only through the kiln calcination once on the shape. The second type is secondary firing. As the name suggests, ceramic mug blanks need to enter the kiln twice for calcination. The first is unglazed firing, usually become ‘plain firing’, the purpose is to increase the mechanical strength of the blank, not easy to damage. Often larger or thinner bone china mugs are often fired twice. After the first firing, a glaze is applied (for information on glazes, please refer to previous issues of our factory), and then a second firing is carried out. Depending on the type of mug, the material and the glaze, the temperatures of the two firings before and after are different. The third type is the triple firing, which requires three trips into the kiln. It is often required for more complex ceramic pieces. The first time is a plain firing, the second time is a glaze firing, and the third time is a decal or hand-painting followed by a firing.

5. Ceramic mug capacity

According to the different needs of use, the capacity of ceramic mugs is also different, the common capacity of 12oz, 14oz, 16oz and so on. The capacity of espresso cups is 2oz, 3oz, 4oz; the capacity of coffee cups and saucers is 6oz, 8oz; the capacity of mugs is 11oz, 12oz, 14oz; the capacity of soup cups is 20oz, 30oz.

6. Ceramic mug shape

Ceramic mugs come in a variety of shapes, the most common are cylindrical straight mugs, drum coffee mugs, tulip coffee mugs, wide-mouth coffee mugs and a variety of special shapes of coffee mugs.

7. Ceramic mug colour

Colour glaze: in the glaze with some kind of oxidation metal, after baking, it will show some kind of inherent colour, so called ‘colour glaze’. Glaze material to add different metal oxides as a colouring agent, in a certain temperature and air temperature in the firing, will show a different colour of the glaze, become a colour glaze. Traditional colour glazes include: blue glaze with iron as the colouring agent; red glaze with copper as the colouring agent; and blue glaze with cobalt as the colouring agent. Historically, there are outstanding masterpieces of colour glazes in many eras, such as the green glaze and jun red in the Song Dynasty, the ji red in the Ming Dynasty, and the Lang kiln red, wu jin glaze, and tea leaf powder glaze in the Qing Dynasty. The difference between colour glaze and ordinary colour glaze lies in the special firing process and formula of colour glaze. Colour glaze glaze, must be calcined at a high temperature of more than 1250 degrees Celsius, in order to show its light as oil, colour as rainbow haze, texture as the unique charm of the waterfall clouds.

8. Ceramic mug packaging

Ceramic mug packaging is divided into two kinds: one is a gift box packaging, more colourful boxes; the other is a security package. Gift box can not choose, however, safety packaging is a must. Because the ceramic mug from the ceramic factory production, need to be transported to the port or airport, for long-distance transport. Safety packaging is used to ensure the safety of ceramic mugs. The outer packaging is an effective way to protect ceramic mugs from damage. Usually requires the outer packaging of ceramic mugs should have a certain compressive strength and resistance to breakage strength. It can protect the whole box of ceramic mugs in the process of transport and storage, without damage.

A small amount of ceramic mugs in the packaging, and a large number of ceramic mugs packaging is not the same. A small amount of ceramic cups are mostly sample packaging. Because the samples are mostly courier channels, in the packaging of ceramic mugs, the use of high-foam polyethylene and corrugated cardboard. First of all, with high-foam polyethylene (bubble wrap) wrapped ceramic mugs, fixed with tape. The thickness of the bubble bag is required to be not less than 1 CM. multiple ceramic mugs packaging is completed, into the corrugated cardboard box.

In summary, after understanding the basics of the various factors of ceramic coffee mugs, we can determine the characteristics of custom ceramic mugs more precisely according to our needs. So that in the custom ceramic coffee mug, the more accurate and detailed information to the ceramic factory (for example: china ceramic mug factory), to facilitate the two sides with a shorter time, lower cost, to solve your custom needs.

6 Dimensions to Help You Choose Ceramic Coffee Mugs

Xinxiang ceramic mug manufacturer, ceramic coffee mugs come in a wide variety of types and styles. How do we choose a ceramic coffee mug that suits us? Or what kind of coffee mug can highlight the characteristics of coffee better when we experience different coffee? Well, China Ceramic Mug Factory will help you choose a ceramic coffee mug from material, capacity, glaze, pattern, shape and colour, 6 dimensions.

1. Material of coffee mugs

The simplicity of ceramic mugs and the roundness of porcelain mugs signify different coffee attitudes. Ceramic mugs have a thick texture and are suitable for deeply roasted and full-bodied coffee. Porcelain mugs have a light texture, soft colour, high density and good heat retention, which can make the coffee in the cup more slowly reduce the temperature, is the most expressive coffee flavour choice. Various raw materials for ceramic coffee mugs.

2. Capacity of coffee mugs

Small coffee mugs (60ml ~ 80ml), suitable for tasting pure quality coffee, or strong single-serve coffee, a cup and a mouthful of portion, can make the aftertaste of the coffee lingering, and show the exquisite flavour of the coffee.

Regular coffee mugs (120ml~140ml), common coffee cups, usually choose such cups when drinking coffee, there is enough space, you can mix your own, add milk and sugar.

11oz Ceramic Mug (300ml or more), suitable for coffee with a lot of milk.

3. Glaze for coffee mugs

There are three ways to divide the color glaze mugs: one is classified according to the firing temperature, divided into high temperature colour glaze (about 1300 degrees), medium temperature colour glaze (about 1200 degrees) and low temperature colour glaze (about 1000 degrees). If 1250 degrees as the boundary, divided into high, low two; Second, according to the nature of the flame after firing is divided into oxidation flame colour glaze, reduction flame colour glaze two; Third, according to the characteristics of the appearance of the firing classification, can be divided into single-colour glaze, double-colour glaze (flower glaze), crackled glaze, no light glaze, crystal glaze and so on. High-temperature colour varieties are very many, the famous purpose of nearly a hundred kinds, can be divided into the following systems: red glaze system, including sacrificial red, jun red, Lang kiln red, glaze red, beauty drunkenness, etc., mainly with copper as a colouring agent. The green glaze system includes celadon green, Longquan, bean green, shadow green, etc., mainly iron as a colouring agent. The blue glaze system includes ji blue, enamel blue, jiqing, etc., mainly using cobalt as the colouring agent.

4. Coffee mug pattern

Some ceramic coffee mugs are not suitable for microwave oven, one of the factors is: pattern paper. Flower paper according to the baking temperature is divided into: high temperature flower paper and low temperature flower paper. Low-temperature paper can not be used in the microwave because of the low operating temperature. So, can ceramic coffee mugs with low-temperature paper still be used in the dishwasher? No, it is not. Why can't low-temperature paper coffee mugs be used in either microwave or dishwasher?

High-temperature paper because of the high firing temperature, in the firing process, the glaze will completely vitrify the paper, in the outer wall of the ceramic coffee mug to generate a protective film. Therefore, high-temperature floral paper coffee mugs are dishwasher safe. Low-temperature paper is not dishwasher safe because of the process. If you use a dishwasher to clean a low-temperature paper coffee mug, the image will most likely be scratched, and the body of the mug will be prone to scratches.

5. Shape of coffee mugs

It was found that coffee was tasted in different shaped mugs and then evaluated in many aspects such as the aroma, bitterness, concentration and taste of the coffee. The results of the experiment show that most people think that the coffee in taller mugs tastes sweeter, and the coffee in ‘skinny’ mugs is more bitter than ‘fat’ mugs. Coffee mugs are also categorised into wide-mouth and non-wide-mouth (straight and close-mouth) cups. Wide-mouth mugs help the aroma of the coffee to spread so that people can smell the coffee more fully. The non-wide-mouth mugs allow the coffee to be more concentrated in the mouth and have a more balanced flavour. This shape of mug allows the taste buds on the tongue to fully experience the flavour of the coffee.

6. Colour of coffee mugs

The study found that compared to clear glass cups, coffee in white cups is darker in colour, which in turn is perceived as more concentrated and more bitter, while coffee in blue cups is perceived as lighter in colour due to the blue contrast, which in turn is perceived as less concentrated and less bitter.

In summary, different ceramic coffee mugs have different characteristics, suitable for different coffee, but also for different moods of you. Beautiful mood, you need the company of coffee, but also the company of ceramic coffee mugs; bad mood, you need different coffee care, but also the care of different coffee mugs. Thank you: coffee!

Characteristics and production of ceramic printing mugs

Xinxiang ceramic mug manufacturer, ceramic printing mug is a paste method to move the colourful pattern on the flower paper to the ceramic mug body. Ceramic decal paper production process for printing porcelain ink, porcelain ink is rolled from ceramic pigments plus oil. Printed with ceramic ink into a flower paper pasted on the ceramic mug, it must be 700-1300 ℃ firing, in order to present a variety of bright colours on the surface of the ceramic cup.

Ceramic printing process is generally: first of all, according to the design, colour separation. According to the characteristics of ceramic pigment overlay colour does not change colour, red, blue, green to be separated. At present, most ceramic mug factories are selected large film flower paper, high quality requirements for printing, the choice of small film flower paper. The quality of the large film flower paper is not as good as the small film flower paper, however, the large film flower paper than the small film flower paper price is low. For more detailed information on ceramic flower paper categories and decal techniques, see: Decal paper categories and decal techniques for ceramic coffee mugs.

Ceramic decal process operation mainly includes the following steps:

1. Preparation

Design pattern: according to the shape, size and use of ceramic coffee mugs, design a suitable applique pattern. Patterns should be creative and in line with aesthetic needs.

Production of printing plates: the designed pattern through the plate-making technology, to produce a plate that can be used for printing.

Prepare ceramic blanks: Ensure that the surface of ceramic blanks is clean, flat and free of impurities such as oil and dust. According to the need to trim and polish the blank.

2. Decal paper production

Selection of paper: the choice of paper suitable for ceramic applique, the paper is required to have a certain thickness, toughness and ink absorption.

Printing patterns: the production of a good printing plate installed in the printing machine, the pattern printed on the paper. The printing process should control the amount and uniformity of ink to ensure that the pattern is clear and colourful.

Hand-painted plate:

Hand-painted plate is more technical, is all by hand technology to depict the screen on each colour palette, with points and lines of the two ways to draw a combination of colour plates. The handmade version of the dot is more suitable for printing ceramic decal paper, because the handmade version of the dot is thicker than the mesh version, due to the ceramic pigment is inorganic pigment, hardness, coarse particles, not easy to crush very fine, so the handmade version of the dot is thicker in the printing process of the ink absorption is more sufficient, so that the pattern of the outline of the part of the display is clear. But the shortcomings are depicting a flower bottom plate labour time is very large, and then the faithfulness of the original poor, has been less adapted to the needs of the production.

Plus network plate method:

Ceramic applique printing is more suitable for direct mesh plate method without the use of two flip photographic plate method, which creates favourable conditions for the applique paper plate. Technology is easy to master, better quality, fast plate making, and colour separation out of the negative picture has been the number of dots, you can directly determine whether the original manuscript with the required number of dots, into the number of conformity. Furthermore, after correction of the negative picture dot film, copy the positive picture dot film can be anti-copy. Reverse copy positive picture, dot evolution amplitude than the positive copy of the larger picture level rich, patterned outline is obvious. In addition, you can also use no network highlights mask for layered burst of light, the level can be pulled wide, patterned outline parts of the layout can be deepened, good picture clarity. Finally, the yin map dot film copy yang map dot, yin map dot and photographic film in the copy machine after pumping, so that the yin film and photographic film tightly together, copy the yang picture dots, point type is relatively strong, small dots are not easy to disappear, but ceramic applique is generally a special colour dedicated to mastering the characteristics of the direct mesh plate making, how to use its characteristics, the quality of the negative plate to improve is crucial. Repairers must first have a certain degree of basic painting, master a variety of painting characteristics, colour combinations, especially on ceramic pigment properties to have an understanding of the basic skills of learning to draw a good plate and the use of drawing instruments.

Drying process: the printed decal paper for drying process, remove excess water and ink on the paper, so that the pattern more firmly attached to the paper.

3. Decal operation

Apply glue: Apply the appropriate amount of glue in the ceramic blank decal position, the glue should be applied evenly to avoid too much or too little.

Applique positioning: the production of good applique paper accurately placed on the ceramic blank coated with glue, to ensure that the pattern matches the shape and size of the blank.

Adjusting the pattern: Gently press the decal paper with hands or tools to make it fit closely with the ceramic blank, and at the same time adjust the position and angle of the pattern to ensure that the pattern is neat and beautiful.

Remove excess paper: After the glue is initially dry, gently tear off the excess on the decal paper to reveal a clear pattern.

4. Firing treatment

Pre-heating treatment: put the ceramic mug blanks with good flowers into the kiln for pre-heating treatment, remove the moisture and organic matter in the blanks, ready for firing.

Firing: according to the requirements of ceramic coffee mugs, set the appropriate firing temperature and time. During the firing process, make sure that the temperature and atmosphere in the kiln are stable, so that the ceramic body and the decal pattern can be fully integrated and cured.

Cooling: After firing, let the ceramic products cool naturally to room temperature. In the cooling process, to avoid sharp temperature changes, so as not to lead to product cracking or deformation.

5. Inspection and packaging

Inspection of quality: the fired ceramic products for quality inspection, check whether the pattern is clear and complete, whether the colour is bright and uniform, as well as whether there are cracks, deformation and other defects in the product.

Packaging and storage: the qualified products will be packaged to ensure that the products are not damaged in the process of transport and storage. At the same time, to do a good job of product labelling and record-keeping for traceability and management.

Through the above steps, you can complete the operation of the ceramic decal process. In practice, it is also necessary to adjust and optimise according to the specific circumstances to ensure product quality and production efficiency.

Characteristics and production process of ceramic drum mugs

Xinxiang custom ceramic mug manufacturer, ceramic drum mugs are made because they are shaped like a drum. the diameter of the body of a ceramic drum mug is larger than the diameter of the bottom of the mug. what are the characteristics of ceramic drum mugs and how are they made?

1. Appearance of ceramic drum mugs

1). Material

Durability: Ceramic drum mugs are made of high-temperature fired clay, which is strong and durable and can be used frequently.

Insulation: Compared with other materials, ceramic has good heat insulation properties, which can keep drinks hot or cold for a long time.

2). Shape and size

Drum shape: These mugs are usually cylindrical, reminiscent of a drum, giving them a unique artistic touch.

Variety of sizes: There are a variety of sizes to choose from, from small espresso cups to large coffee mugs, to meet different drink preferences.

3). SAFETY

Food safe: Ceramic mugs made with safe glazes are safe to drink from, and even better for hot coffee.

Heavy feeling: Ceramic mugs usually have a solid and heavy feeling, which makes people feel that they are of high quality and very stable when filled.

2. Features of ceramic drum mugs

1) Ceramic drum mugs can't be made by conventional pressing method because of the curvature of the mug body. Therefore, ceramic drum mugs are mostly made by injection method. However, there is a kind of fat ceramic mugs, the body of which is also curved, and it is made by pressing method. It is different from ordinary ceramic drum mugs, the main difference is that the mouth of fat ceramic mugs is bigger.

2). Ceramic Drum Mugs Because of the larger capacity and heavier mugs, ceramic drum mugs are mostly made of stoneware. In this way, ceramic drum mugs are heavier in the hand, with better heat insulation and heat preservation.

3) Ceramic drum mugs are baked with high temperature.

4).The pattern of ceramic drum mugs is determined according to the customer's demand for the pattern. They can be divided into high-temperature and low-temperature patterns. (For detailed information, please refer to: Ceramic flower paper classification and characteristics of appreciation.)

5).Ceramic drum mugs are suitable for microwave and dishwasher. This depends mainly on the type of flower paper. If it is a high temperature flower paper or ceramic drum mugs with a solid colour glaze without a pattern. ceramic drum mugs are safe for microwave and dishwasher use. （What kind of ceramic coffee mugs are not dishwasher and microwave safe?)

3.The process of making ceramic drum mugs

1). Moulding

Before closing the mould, the working surface of the model should be cleaned up, no dry mud or dust should be left. And check whether the working surface of the mould is smooth and clean, with or without holes and lubricant traces. If it is normal, the mould can be closed. If there is a big gap in the assembled model, use soft mud to block the gap at the joints to avoid leakage of slurry. When using the model should not be too dry or too wet, the amount of water is generally controlled at 4% -6%.

2). Grouting

For single-sided grouting, the slurry filled model can be, such as mud layer thickening to the required thickness, pour off the model of excess slurry, in order to avoid pouring off a small amount of residual slurry in the billet in the body of the surface of the uneven distribution of the production also need to pour off the slurry after the billet with a billet model for the dumping of slurry to ensure that the distribution of residual slurry to ensure that the distribution of mud is uniform to avoid mud wisps. For double sided grouting, the grout must be replenished one after another until all the cavities in the model become blanks. There is no need to pour and dump the slurry.

3). Drying

Just formed due to the high water content, low strength and can not immediately release the injection, need to take the mould to dry for a certain period of time, this drying is called green billet drying, in the green billet drying period, due to the evaporation of water and the mould continues to absorb water, the injection of the water continues to decline, the billet contraction and detachment of the model, and at the same time gradually increase the strength, then can be removed from the mould.

4). Demoulding

After demoulding, the blank should be held gently, put flat, put right, put stable, and prevent vibration.

5). Bonding

Bonding is for ceramic cups and other blanks can not be formed in one piece of the necessary process, the bonding process refers to the use of a certain consistency of bonding mud cups and mugs to stick together in the process.

6). Repairing

For the bonding of ceramic drum mugs, due to its surface is not very smooth, the edge of the mouth has a burr, and some still have a mould seam trace, the need for ceramic cups for beautification, this step is called repair blank. Repair blank is a necessary work of injection moulding ceramic mugs. We usually see flat, smooth ceramic coffee mugs, mainly because of trimming. There are wet repair and dry repair ceramic drum mugs using wet repair. Wet repair is a lot of water in the blank, still wet and soft case, suitable for more complex shape or need to be wet by the blank, this time the operation is easier and repair of blanks, the disadvantage is that it is easy to move and operate in the process of the blanks are injured and caused by deformation. China ceramic mug factory since 2022 are using automatic repair machine, not only can improve the efficiency of repair, but also improve the quality of repair, eliminating the deformation of the repair.

7). Glazing

The completely dried mugs are glazed. There are many different types of glazes (Glaze Composition and Classification). The easiest glaze to apply is a single colour glaze, in which the whole of the moulded mug is placed in the glaze. If the mug requires multiple glaze colours, then the operation is a little more complicated. An example is the common two-colour glazed mug - one colour on the outside and another on the inside. The glazing process for a two-colour glazed mug is as follows:

a). The mouth of the mug is glazed. The mouth of the mug is where the two colours join, so it needs special treatment. The mouth of the mug should be dipped in the corresponding glaze, and to prevent the two glazes from overlapping, the glaze that is dipped in the mouth of the mug should be filled with a water-resistant agent.

b). Glaze the inside. Place the ceramic mug with the mouth down into the machine. With the movement of the conveyor belt, the glaze nozzle will invert the inside of the mug, evenly sprayed with glaze colour.

c). Outer wall glazing. Place the dried mug into the glaze liquid, called dip glaze in the industry.

8). Firing.

After drying the glazed mugs, they can be fired in the kiln. The time is more than 10 hours, depending on the type of mug. In addition, according to the customer's requirements for the colour of the mug, there are high temperature firing, medium temperature firing and low temperature firing.

9). Out of the kiln

After the ceramic drum mugs are fired, they will be quality checked and packed after leaving the kiln (How to pack the ceramic mug so that it will not be damaged?).

Ceramic drum mug factory combine functionality with artistic design, making them a popular choice for beverage containers. Their unique mug shape determines the raw materials used to make them, the production process and the firing temperature.
