Founded in 1978, Zhongde is a professional injection molding supplier focusing on OEM & ODM customized services. Based on 40 years technology deposition, we have developed a one-stop solution from mold designing and rapid prototyping to mass production. Our manufacturing capabilities include plastic injection molding service, compression molding service, CNC machining service, metal stamping service, 3D printing service,,etc.  


 is the most common manufacturing process for the fabrication of large quantities of plastic parts. As an ideal method to producing high volumes plastic parts in the same shape, Plastic custom moulding can be used to create various of plastic parts, which vary greatly in size, complexity and application. Almost every plastic item around you was manufactured by injection molding.


the  molding at Zhongde is a standard process involving a stainless steel mold, it can be divided into six stages: mold clamping, injection molding, pressure holding, cooling, mold opening, and product removal. at a certain temperature, the completely melted plastic material is stirred by a screw, injected into the mold cavity with high pressure, then cooled and solidified into the final plastic molded parts.Now the plastic injection price  is pretty proper.

Additives of Plastic Injection Molding




UV absorbers

Absorb UV radiation, slowing down the degradation of the material when used outdoors.

Flame retardants

Prevent ignition and inhibits spread of fire.


Increase flexibility and promotes plasticity, reducing brittleness of the material.


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.



Surface Finishing of Plastic Injection Molding





the mold is smoothed and then polished with a diamond buff, resulting in parts with a mirror-like finish.


the mold is smoothed with fine-grit sandpaper, resulting in parts with a fine surface finish.


the mold is smoothed using fine stone powder, removing all machining marks.

Textured finish

the mold is first smoothed with fine stone powder and then sandblasted, resulting in a textured surface.

as-machined finish

the mold is finished at the machinist's discretion. Tool marks may be visible.
