Rubber keypad for TV -silicone compression molding
What is silicone compression molding?

What is silicone compression molding process?
Prepare the raw silicone material for silicone compression molding .
The compression molding silicone raw material is small shape block and is stretch solid body. The silicone compression molding raw material is ivory-white or translucent color. Generally the transparent silicone color can not be transparent as the glass.
Milling the silicone compression molding silicone resin .
- Kneading raw rubber alone for the purpose to improve their plasticity called mastication. Mastication good raw rubber and compound mixing called mixing. Mixing resin is before rolling, extrusion, die before loading to further increase the plasticity and improve texture uniformity and promote its softening, this mixing process together with a little heat called heated mixing. In order to mix the ingredients well diversified, with a small roll open mill to make the thin silicone sheet called refining.
- Please kindly noted the silicone color is made on the milling process. Generally it is colorful silicone block raw material to mix with the natural silicone block to make the silicone compression molding parts color.
- After the silicone raw material milling, we should cut the silicone sheet and weight the silicone sheet to make sure it is suitable for the silicone compression molding parts molding.
Rubber keypad for TV- silicone compression molding tooling
Silicone compression molding tooling is much more simple than the, it is made with top and bottom plate, core and cavity is on the bottom plate and top plate. The steel for the silicone compression molding tooling can be S50C or P20. Generally lead time to make a silicone compression mold is from 7days to 15days. This is shorter than to make injection mold.
Rubber keypad for TV-rubber parts surface finishing
Generally silicone compression molding parts is with sand blast finishing, it is like fine texture. Also we can chrome plate the core and cavity to have the gloss finishing for silicone compression molding parts.
