Compression molding is a method of forming plastic or rubber in a closed cavity by heating and pressing. It is a good choice for manufacturing large pieces, and low-to-medium quantities production with competitive tooling price.
The materials of Zhongde compression molding service include both plastic and rubber. The molding pressure of the compression molding process is higher than other process methods, and it belongs to high-pressure molding. We utilize hydraulic presses that can control the pressure, and high-strength, high-precision, and high-temperature resistant metal molds to guarantees the quality of molded products. Using the compression molding process, we can guarantee high-efficiency production, ensure accurate products, and smooth surface.
Plastic compression molding, rubber compression molding, silicone compression molding are all available.
