Silicone Rubber Molding Manufacturer

Silicone material after blending will be collected in large rolls covered with film to prevent dust or dirt. It then will be cut into slices by an automatic cut machine. The slices’ length and width will be controlled according to the silicone part’s weight to be molded. Silicone blanking makes it easier for our molding operators to weight the material during silicone molding production.

Silicone material will be fully cured under high temperature and pressure from vulcanizing molding machine, then the silicone parts are formed. Our molding department is equiped with 8 high precision automatic vacuum vulcanizing machines which can be used to craft more high performance silicone parts. Our sophisticated molding machines, coupled with our skilled operators, provide the capacity and flexibility to mould high-quality, high-volume silicone parts in short peroid.

The vulcanizing molding machine will automatically relieve pressure after the silicone is fully cured, allowing molding personnel to remove the silicone-molded pieces by pulling out the tool mold. The raw material will be repositioned for the following vulcanization cycle.

Silicone Flash – Is a thin flap of material at the parting line where the mold splits. Due to the low viscosity of silicone material and high molding pressure during heating and curing, The pressurized silicone material will flow to every spaces of tool mold. Flash can be minimized with favorable designs and better tooling and accurate material weight during vulcanizer molding production. Flash will be removed mainly by hands, cryogenics deflashing can also be applicated for some cases.
