China Custom High Precision Plastic Injection Molding Service

Plastic injection molding 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 injection molding 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 plastic injection 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.

Additives of Practical Plastic Custom Injection Molding Manufacturing

NameDescription
UV absorbersAbsorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardantsPrevent ignition and inhibits spread of fire.
PlasticizersIncrease flexibility and promotes plasticity, reducing brittleness of the material.
ColorantsUsed to color plastics.
Carbon fibersIncrease strength, toughness, and rigidity of the material at the expense of making the material more brittle.
Glass fibersIncrease 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 Dies Services

NameDescription
GlossyThe mold is smoothed and then polished with a diamond buff, resulting in parts with a mirror-like finish.
Semi-glossThe mold is smoothed with fine-grit sandpaper, resulting in parts with a fine surface finish.
MatteThe mold is smoothed using fine stone powder, removing all machining marks.
Textured finishThe mold is first smoothed with fine stone powder and then sandblasted, resulting in a textured surface.
As-machined finishThe mold is finished at the machinist's discretion. Tool marks may be visible.
