What is the production process of mobile phone silicone protective case

The mobile phone silicone protective case made of liquid silicone has the characteristics of wear resistance, tear resistance, good elasticity and very comfortable touch, and it is also anti-yellowing and waterproof. So what production links do you have to go through when producing mobile phone silicone cases?

Rubber mixing: including mixing of raw rubber, color matching, weight calculation of raw materials, etc.;

Vulcanization molding: high-pressure vulcanization equipment is used to vulcanize at high temperature to make the raw material of silica gel into a solid state;

Trimming: The silicone sleeve product that comes out of the mold will have some useless burrs and pore debris, which need to be removed; in the industry, this process is completely done by hand, and some factories also use punching machines to complete it;

Polishing: Since the production environment is not a vacuum, the silicone mobile phone case is inevitably contaminated with dust and impurities, or some products are soiled by the start-up personnel, and some cannot be cleaned. At this time, the mobile phone case can only be modified by polishing. As long as the customer accepts, subtle Grinding can reduce processing costs and waste;

Cleaning: Most silicone products need to be cleaned. Dirt is a relatively late treatment process, because the previous process may stain the silicone mobile phone case. You can blow off the dust and impurities with an air gun, and then use a dust-free cloth and Tianna water cleaning;

Spray hand oil: Most silicone mobile phone cases need to be sprayed with hand oil. Completing this process will improve the quality of silicone mobile phone cases. Most ink manufacturers can provide environmentally friendly hand oils.

A good mobile phone case looks at the design and the texture at the same time.

Baking: After spraying the hand oil, the mobile phone cover must be dried. After baking in a high-temperature oven for about 15 seconds, it can be moved aside to cool and pack.
