Our Capabilities

RevPart is more than just another CNC plastic machine shop. RevPart offers conventional plastic injection molding service from 75 to 500 tons, as well as high-speed, all-electric injection molding with wall thicknesses down to 0.3 mm. We specialize in providing high-quality, quick turn prototype injection molding and short-run parts in a fraction of the time of other facilities, and will never turn down a job for being too small. Types of injection molding services that RevPart provides include:

How Does Injection Molding Work?

Plastic injection molding is a widely used manufacturing method, where high-temperature, melted plastic resin (the “shot”) is forced into a mold cavity. There, it is left to cool and take the shape of the mold, producing the desired part. Once the plastic resin in the mold cools, the part is released and the process starts again. Plastic injection molding machines consist of three main parts: the mold, the injection unit and the clamping unit.
