Comprehensively understand the characteristics of pad printing silicone rubber and pad printing ink

Introduction:

Pad printing silicone rubber, a printing method of silicone rubber. Ink is mainly used to print words, graphics and images on the surface of silicone products through pad printing, and now it is becoming an important special printing. For example, words and patterns on silicone keys on the surface of mobile phones are printed in this way, and silicone rubber products of many electronic products such as computer silicone keyboards are printed on the surface by pad printing. The process of transfer printing silicone rubber is relatively simple. The steel (or copper, thermoplastic) intaglio is used, and the curved surface transfer head made of silicone rubber is used. The ink on the intaglio is dipped on the surface of the transfer head, and then the text, pattern, etc. can be printed by pressing on the required object surface. The silicone keys with good pad printing have excellent durable grinding performance, no deformation, no oil and good ink transfer performance. The transfer printing silicone rubber is used for printing PVC toys, electronic products, lighting, plastic toys, electroplating products, trademarks, irregular patterns, etc.

characteristic:

1. Good oil filling and dropping effect

2. The colloid is delicate, with good resilience, and there are many pad printing times, no impurities or particles

3. Clear pad printing pattern

4. Low viscosity and good fluidity

5. No shrinkage, good oiling, clear pad printing pattern

It is mainly used for printing irregular patterns such as plastic toys, electroplated products, electronic toys, trademarks, communication equipment, craft gifts and stationery.

Type of pad printing machine:

1. According to the classification of transmission mode, according to the different transmission modes of the main movement of the pad printing machine, it can be divided into three types, namely, manual mechanical pad printing machine, electric pad printing machine and pneumatic pad printing machine. The pneumatic pad printing machine is widely used at home and abroad because of its simple structure, convenient operation and smooth movement. It is the mainstream of the current pad printing machine.

2. The pad printing machine can be divided into monochrome pad printing machines according to the number of printing colors and the number of printing colors completed in a printing process. Multicolor pad printing machines such as two-color pad printing machines and multi-color pad printing machines can be divided into shuttle type and conveyor belt type multi-color pad printing machines according to the different transmission modes between colors.

3. According to different ink storage methods, it can be divided into oil basin type and oil cup type pad printing machines. The oil pot pad printing machine is a commonly used form at present. The oil cup pad printing machine is a sealed ink storage device, which is relatively environmentally friendly, and can ensure a better stability of the ink in the printing process.
