It is also possible to have a combination of liquid silicone rubber (LSR) and liquid silicone rubber (LSR). This overmolding technique requires extensive skills and know-how not only of the materials, ofliquid injection, but also in research and development and of regulatory standards. Indeed in order to obtain precision parts, the material combinations need to be thoroughly studied.
The mold needs to be meticulously designedand the injection process skilfully controlled and monitored. The injection tool needs to be adjusted with high precision in order to guarantee a product that has no impurities, that is correctly fused with no gaps and that is burr-free.
