Plastic Injection Molding Service

At Jierui Prototype, we specialize in high-quality custom plastic injection molding and mold tool making. Plastic injection molding is by far the industry’s most common way to manufacture plastic parts, especially when making larger quantities. We provide custom molding for 50 to 100,000+ injection molded parts as well as a wide range of other manufacturing and finishing services to complete your project.

What Is Plastic Injection Molding?

Plastic injection molding involves melting granular plastic pellets into a liquid form and then compressing this liquid into the empty cavity of a mold tool. The plastic will retain the shape of the mold as well as the surface texture of the walls of the cavity. After an optimized injection and cooling phase, the now solidified plastic part is ejected and the molding cycle is repeated. This molding cycle can take from as little as a few seconds to several minutes depending upon part size, molding resin and part design.

Advantages Of Plastic Injection Molding

We have thousands of different types of plastic available for you to choose from, for a wide range of mechanical and cosmetic properties.

Plastic injection molding is great for larger volumes. For smaller volumes we might recommend other services like CNC machining, vacuum casting or 3D printing depending on the needs of your project.

Hundreds of thousands of parts can be produced from a single mold tool.

Your part can have excellent surface quality finishes in a wide range of polishes and textures.

Injection molding allows you to do overmolding to combine different types of plastic in one piece. It is ideal for lightweight parts that are immune to corrosion.
