Stainless steel bottle tumbler water transfer process: Water transfer technology is a kind of printing that uses water pressure to perform polymer hydrolysis on transfer paper/plastic film with color patterns. The stainless steel thermos cups with wood grain and jade grain patterns seen on Amazon are all manufactured using a water transfer process. The most outstanding of these are S’well water glasses and Chilly’s.
Stainless steel bottle cup thermal transfer process: The thermal transfer process printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts dot printing (resolution up to 500dpi), the pattern is pre-printed on the surface of the film, and The pattern is rich in layers, bright in color, ever-changing, small in color difference and good in reproducibility, which can meet the requirements of the designer and is suitable for mass production; it is widely used in the metal water cup manufacturing industry.
Advantages and disadvantages of water transfer and thermal transfer printing:
- Advantages of water transfer printing: it can be produced without specific equipment investment; water transfer printing patterns can be made on the surface of many products that are not resistant to high temperature; it can be printed on curved surfaces; no need to coat first.
Disadvantages of water transfer printing: the transfer effect is too poor; a large amount of polluted water is generated; the material cost and labor cost are extremely high.
- Advantages of thermal transfer printing: good transfer effect, very beautiful, low cost of artificial materials, fast production speed and high efficiency. It has the properties of corrosion resistance, impact resistance, aging resistance, wear resistance, fire resistance, and it can be used outdoors for 15 years without discoloration. The wood grain is clear and realistic, and the color is bright.
Disadvantages of thermal transfer: the product needs to be resistant to high temperatures
The difference between water transfer printing and thermal transfer printing:
- Water transfer printing is derived from the printing process. The principle of molecular diffusion is used to transfer the pattern (transfer film) to the object. Thermal transfer printing is realized by thermal transfer of thermal sol or thermal transfer coating absorbing thermal sublimation ink. transfer.
- Thermal transfer printing needs to be achieved by heating devices, while water transfer printing only needs to use water.
