Custom Plastic And Rubber Compression Molding Service Company

Compression molding is a method of forming plastic or rubber in a closed cavity by heating and hot pressing. It is a good choice for manufacturing large pieces, and low-to-medium quantities production with competitive tooling price.

The materials of Zhongde, a reputable company providing customized 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.

Other types: cold compression molding, vacuum compression molding, direct compression molding, composite compression molding...

Advantages of Compression Molding Service

Less mold structure with competitive tooling price

Evenly heated mold cavity with good dimensional stability

Little material waste suitable to work with expensive material

Available for forming large flat products

More than hundreds of colors to choose from

Capabilities of Custom Compression Molding

Name	Description
Rapid tooling	Mold working life time up to 20,000 runs. Short machined time.
Production tooling	Traditional molds, used for mass production
Single cavity molds	Molds only produce one part per cycle, mostly used for low production rates.

Additives of Custom Compression Molding

Name	Description
UV absorbers	Absorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardants	Prevent ignition and inhibits the spread of fire.
Plasticizers	Increase flexibility and promotes plasticity, reducing brittleness of the material.
Colorants	Used to color plastics.
Carbon fibers	Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle.
Glass fibers	Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle. It is more flexible than carbon fibers.
