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.
