Ceramic Mug Group, Coated mugs are also called
sublimation mugs, which is a kind of mugs specially used for heat transfer printing. As we all know, ordinary cups can't do heat transfer. So how can coated mugs accomplish the transfer of pictures? There are several important materials and a special process. Firstly, there is a special coating on the surface of the cup, so it gets the name of coated cup. Secondly, the flower paper and ink for heat transfer printing are not ordinary. On the basis of these two hard materials, a heat transfer machine is needed to print the pattern onto the mug.
1.Heat transfer coating
Using the world's two best performance resin materials silicone and PTFE (aka: Teflon, Teflon, PTFE, F4, Plastic King), synthesized a new generation of fluorosilicone modified thermal transfer coating.
1). History of Thermal Transfer Coating
At the end of the 20th century, there was a DIY gift boom in the U.S., which at that time was mainly clothes and things of that kind. Later, people wanted to apply this kind of things on top of porcelain, metal. But these things are more solid, can not complete the operation. Professor Smith of the University of Pennsylvania, the United States, developed into a graphite coating. This is the originator of the thermal transfer coating. With the development of the times. The coating is also constantly developing, from the past multi-molecule to single molecule.
2). Introduction of Thermal Transfer Coating
Early thermal transfer coating mainly uses thermosetting acrylic resin, amino resin, epoxy resin, or silicone resin, polyester, polyurethane, polyurethane and other modified synthesis, the application time has been more than twenty years. With the development of material science and technology, we have synthesized a new generation of fluorosilicone-modified thermal transfer coatings by using two of the world's best-performing resins: silicone and polytetrafluoroethylene (a.k.a. Teflon, Teflon, Teflon, F4, Plastisol) after a long period of experimentation.
Silicon is one of the most abundant elements on earth, one of the basic substances for the origin of life, and one of the most hygienic materials; tetrafluoroethylene is one of the most chemically stable resins and plastics, with excellent corrosion and weather resistance.
The physical state of the super thermal transfer coating resin is a viscous liquid, without adding any solvent, it is sprayed directly with a special spray gun with excellent leveling, and it can be fully cured by baking at only 200℃, and the gloss and pattern reproduction of the cured coating are excellent.
3). Characteristics of thermal transfer coating
(1). It can be repeatedly washed in dishwasher for a long time, the image does not fade, the edge of the pattern is clear, and the color does not spread;
(2). Ingredients are in full compliance with California FDA standards, and can be used to serve drinks or food directly.
(3). Excellent heat fastness, even if the image has just been transferred at 200 ℃ before it cools down, you can't pick it with your fingernails; the coating won't be broken when you collide with each other during hot water cleaning.
(4). When transferring the heat sublimation ink can be crosslinked with the coating reaction, generating new substances, pigments can be firmly fixed in the coating, even if the temperature is increased again, the ink will not diffuse to the un-transferred area; this feature can be two or more times in the same image of the cup or other artifacts with the material, randomly transferring the required picture.
(5). Transfer the characteristics of non-diffusion, can be applied to all daily-use ceramics, just ceramic decal paper pigments from high-temperature ceramic pigments, changed to thermal transfer ink can be, and decal the same way and the traditional way, just baking temperature from 800 degrees above down to 200 degrees, a large amount of energy savings, improve the clarity of the picture.
(6). Normal state can be used for 50 years, resistant to pressure cooker cooking or high pressure steam for a long time without dropping the coating does not fade.
4). Coating spraying operation
Spraying layer to the cup should have a certain method, otherwise the coating sprayed unevenly, will affect the quality of the coated cup.
A, dip-coating construction (can also be sprayed construction) ---- is suitable for small processing treatment
(1). Prior to processing: the surface of the treatment thoroughly clean; wipe dry with a cloth, do not have water; and then put in the oven to dry (150 degrees); after taking out the cold sure.
(2). Cold sure after the cup immersed in the grass-roots solution, in completely coated tilt out, if the mug, you can not let the coating immersed in the cup, porcelain mugs can not need to be soaked in the cup, only need to soak the outside can be.
(3). Put the soaked mugs in a dust-proof cabinet or in a closed room for 5-10 minutes, let the treatment cool and dry.
(4). Residual heat the oven to 200°C and bake the coated cups in the oven for about 15-20 minutes.
Attention:It must be stirred well before use, and seal the lid of the can after use. This product is flammable and dangerous goods, please keep away from fire and smoke, placed in a cool, dry place sealed and stored.
B. Spraying construction---applicable to a large number of processing treatment using tools.
(1). Spray gun (market reference price of 200-300 yuan)
(2). Air pump (air compressor) (market reference price of 1000 yuan -2000 yuan)
(3). Exhaust equipment, such as: axial fan (market reference price of 500 yuan - 600 yuan)
(4). Industrial oven with blower. (Market reference price of 1000 yuan - according to the production volume of different power to choose a different price)
Operation process.
(1). in the product surface according to the horizontal vertical horizontal vertical order evenly spray four times.
(2). in the room temperature dust (such as wooden cabinets) in the plane for 5-10 minutes, let the processed matter cool and dry.
(3). Bake in an oven at 200 degrees or higher for about 20 minutes.
(4). Allow to cool at room temperature.
2. Production of thermal transfer paper
The production process of thermal transfer paper is similar to the printing process, i.e. text, drawings, photographs and other original manuscripts by plate making, inking, pressurization and other processes, so that the sublimation thermal transfer ink is transferred to the base paper through the form of offset printing (or gravure printing, silkscreen printing). The base paper for transfer printing should Select high temperature, heavy pressure, prevent bleeding, high surface smoothness, low permeability of dye gas and high tensile strength paper, such as coated paper, 80 grams of double-glued paper, and so on. Sublimation thermal transfer ink selection is also a work that can not be ignored, the transfer image is bright, its resistance to friction, firmness, and so on. Whether the transferred image is bright, its friction resistance, firmness and adhesion is the strongest, the quality of sublimation thermal transfer ink plays a decisive role. The difference with printing is that the dye in the transfer ink is sublimated by heat and penetrates into the molecular structure of the object, and after sublimation, it forms a brightly colored Image. The image will not fall off, cracking and fading, sunlight resistance, so sublimation heat transfer products have the advantage of durability.
3. Bake printing operation
Clean the surface of the mug with a flannel, wrap the transfer paper around the mug, fix it with high temperature tape, put it in the mold cavity of the hot cup machine, push the pressure handle, if the pressure is too big or too small, you can adjust the push rod stroke.

Quick baking: In the state of starting temperature, place the coated cup, press the pressure handle, press the execution key once until the buzzer gives out a long tone, and then press the execution key once, and the stamping is finished.
4. Coating cup type
There are many kinds of coated mugs, mainly
ceramic mugs, side color mugs, inner color mugs,
full color mugs, conical mugs, flared mugs,
color changing mugs, animal mugs, children's mugs, coffee mugs, etc., there are a lot of styles of cups, which is more to meet the market demand.
Summarize
Coated mugs are printed by heat sublimation transfer, in which heat transfer ink is sublimated onto a ceramic mug with a coating at a temperature of about 200 degrees Celsius. The screen printing of heat transfer mugs is more flexible and convenient. For example, a small-scale corporate promotional activity requires dozens of gifts. Then we We can print the event photos or advertisement slogans onto the coated mugs. We can print as many mugs as we need. And we can print different patterns. Of course, if it is a large-scale publicity, the need for custom advertising mugs, or through similar Xinxiang ceramic mug manufacturer direct production, better quality and price. direct production, better quality and lower price.
