Silicon Cup Sleeves’ Production Process

Silica gel cup sleeve uses high temperature vulcanized rubber as the main raw material and produced by compression molding then moulding vulcanization:

1. Silicone raw materials’ preparation: it includes raw rubber mixing, color of improvement, calculate the weight of raw material, etc.

2. Mold forming: Make a mold of silicone rubber sleeve, then make a preliminary already molding silicone rubber case by the silicone mold.

3. Silicone protective covers’ trimming: because during the molding process, there will be some raw edge stick on products, so need to remove them by hand.

4. Silk Screen printing process: Silk screen printing is made for the silicone sleeves’ surface, which means to add some patterns or characters, to make the user easy to use, also can the products more beautiful.
