Product Description

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, custom molding service,etc.

Plastic injection mold and 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 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 precision 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.Now the plastic injection price is pretty proper.

Additives of Plastic Injection Molding

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 Plastic Injection Molding

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.
