Precision Plastic Injection Molding China Manufacturing Additives



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 Cheap/Low-Cost Plastic Injection Molding Services




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.
