ZHONGDECustomizing | Manufacturing
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.
Mold working life time up to 20,000 runs. Short machined time.
Traditional molds, used for mass production
Single cavity molds
Molds only produce one part per cycle, mostly used for low production rates.
Molds can produce more than one part per cycle, used to increase production rate.
Molds produce two or more different parts per injection cycle, the parts should be of the same material and color.
Steel P20, H13, S136, 2316, 2344, 083,718H, SKD618, etc.
Family molds, single and multi-cavities molds
3 years inactivity
Guaranteed Mold Life
We can remachine the molds if there are any changes required, basis on mold structure.
Lifetime warranty on production molds

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

Who owns the mold?
The mold belongs to you. Zhongde is only responsible for saving the mold for you and will not use it for other customers.
What is the service life of the mold?
Generally speaking, one set of molds can produce millions of products, and we will provide mold maintenance and repair services. If the upper limit of mold usage is reached, we will reopen a set of molds for free.
What are types of compression molding?
There are two types of compression molding process, i.e., cold compression and hot compression moldings.
