Why did imr products pass uv lamps?

IMR(In Mold Rolling) is a precision printing decoration technology, which is mainly used for the decoration of 3C, automobiles and other plastic products. The thermal transfer film is put into the injection mold, and the pattern on the thermal transfer film is transferred to the product by using the temperature and pressure of the melt in the injection process. The whole system consists of film feeder, mold, thermal transfer film and injection molding machine.

Because UV can accelerate the curing speed of injection molding, which is one of the functions of ultraviolet rays.

1. Spraying: Generally, plastic spraying companies such as mobile phone shell spraying, cosmetic boxes, MP3 small household appliance shells are the majority. The two industries, mobile phone shell spraying and uv printing, have different requirements for uv, depending on their respective products and equipment. Most mobile phone shell spraying companies have 6-8 tubes (in one coating line). As long as the parameters are provided correctly and the specifications and parameters of their ultraviolet lamps are known, the replacement can be guaranteed. For example, the tubes of Japanese EYE have been successfully replaced by Tianjin Risent UV, and many of them are used in China. The price of eyes is 3000-4000 yuan. 2. Printing: screen printing, offset printing and five-color printing are mostly used. Uv protective glue is used for U disk and CD, and uv ink is also used for screen printing when printing CD. In screen printing, most of them are printed with uv ink now. It has the advantages of fast drying, good adhesion, and various properties meet the standards (adhesion, wear resistance, etc.). ).
