Custom China Precision Plastic Injection Molding

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

As a reputable injection molding company in China, Zhongde supplies custom molding services including China precision plastic injection molding and rubber injection molding, as well as over-molding and insert molding, all with affordable prices and considerate service. The plastic injection molding made at the Zhongde factory is a standard process involving a stainless steel mold.

What's the Features of China Plastic Injection Molding?

There is a perception of China being a low-quality supplier. However, China is undergoing a transition, with Chinese plastic molding manufacturers like Zhongde leading the way in offering high-quality plastic injection molding services and efficient production. Zhongde factory works 24 hours with three shifts per day. Our employees happily accept overtime which allows us to complete projects very quickly. With a closed-loop production system and mature technology, the price of custom-made plastic molds made by Zhongd is more competitive than other global plastic injection suppliers/companies and other Chinese plastic molding manufacturers.

Precision Plastic Injection Molding China Manufacturing Additives

Name Description
UV absorbers Absorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardants Prevent ignition and inhibits 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.

Surface Finishing of Cheap/Low-Cost Plastic Injection Molding Services

Name Description
Glossy The mold is smoothed and then polished with a diamond buff, resulting in parts with a mirror-like finish.
Semi-gloss The mold is smoothed with fine-grit sandpaper, resulting in parts with a fine surface finish.
Matte 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.
