Custom Compression Molding Service

 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.

Multi-cavity molds

Molds can produce more than one part per cycle, used to increase production rate.

Family molds

 

Molds produce two or more different parts per injection cycle, the parts should be of the same material and color.

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.

What are all the design guidelines required to develop a plastic part?

图片
  The structural design of plastic product development should follow the following principles:   a. The structure design should be reasonable: the assembly gap is reasonable, and all plug-in structures should be reserved for gaps; ensure sufficient strength and rigidity (safety test), and properly design a reasonable safety factor.   b. The structural design of plastic parts should comprehensively consider the manufacturability of the mold, and simplify the manufacturing of the mold as much as possible.   c. The plasticity of the structure of plastic parts should be considered, that is, the injection molding production efficiency of the custom plastic injection molding companies should be high, and the rejection rate of injection molding should be minimized.   d.  Consider facilitating assembly production (especially not conflicting with assembly).   e. The structure of stamping plastic parts adopts standard and mature structure as much as possible, so...

Something you need to know about stamping mould

Oct 10-2020 Views: 638 1. What is the effect of the deep sill (drawing rib) in the cover mold? The effects of the deep drawing threshold (drawing bead) are as follows: 1. Increase the friction resistance of the feed material, so that the surface of the deep drawing part bears sufficient tensile stress, improve the bending stiffness of the deep drawing part and reduce the concave surface, distortion, slack and wave pattern caused by the resilience; 2. Adjust the fluidity of the material to make the fluidity and frictional resistance of each part of the whole drawing process equal, or make the amount of material injected into the mold suitable for each part of the steel part to avoid the situation of "less wrinkles, less cracks"; 3. Expand the scope of adjustment of the hemming force. On the double-action punching machine, adjusting the height of the four corners of the outer guide rail slider only roughly adjusts the hemming force, and it is not possible to control t...
