Custom Compression Molding Service
Compression Molding
Cold 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 plastic compression molding products process is higher than other process methods, and it belongs to high-pressure molding. As one of compression molding companies, 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...
What are Three Advantages of Compression Molding Services?
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
Advantages of injection moulding over compression mouldin

Custom Compression Moulding Process
Compression molding is a tried-and-true method of manufacturing simple pieces. The process start from giving amount of uncured material placed into a mold cavity, which is then closed and heated. When the parts have cured, they are removed from the mold.
Custom Rubber Compression molding Process
What is compression moulding used for？
Compression moulding is a composite manufacturing process normally used to produce composite components in high production volume, generally used to make larger flat or moderately curved part
What products are made by compression moulding
Compression molding is a process of molding in which a feeding material is placed into an open, heated mold cavity. Many products can be produced by compression molding, such as rubber gasket, handles, automotive parts and many other large size products.

What Materials are Used in Compression Moulding
In addition to the general materials listed below, Zhongde can also modify the materials according to the special needs of customers. Our professional engineers will adjust the raw material formula to meet the unique conditions of use.
Compression molding plastic material
Thermoset plastics and Thermoplastics are two types of material most often used for compression molding. Thermoset plastic often refers to polyurethane, unsaturated. Common types of thermoplastics are UHMWPE, PTFE.
UHMWPE | Ultrahigh molecular weight polyethylene
PTFE | Polytetrafiuoroethylene
Compression molding rubber material
A wide range of rubber material can be process by compression molding ,including Butyl, Natural Rubber, Neoprene, Nitrial, SBR, etc.
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. |
