The improvement of the mold surface gloss of the silicone Injection molding machine needs professionals to operate. During the promotion of rubber products, some products need matt and some need bright, which depends on the situation. Some customers require that the SBR rubber products have a shiny surface. The rubber mold is a metal mold, and the mold temperature is 150 ℃.

Through specific analysis of specific problems and on-site testing, the following two solutions have been proposed:

1. The mold is treated with water-based semi permanent Sakurai release agent, once per shift (8 hours), spray 4 layers each time, and then cure at 150 degrees Celsius for 10 minutes. Before putting in the film, spray one layer of Paint thinner (1:80 weight ratio) of water spraying Sakurai release agent. Then put on the film for production, and spray Paint thinner of release agent every time when demoulding. By doing so, the surface of the product is noticeably brighter than before. Customer can accept

2. Mold treatment Before each film is put into the film, spray (Yingjing) brand water-based release agent Paint thinner (1:80 weight ratio), one layer, and then put into the film for production. The product has significantly improved its brightness.
