High repeatability

Versatility in materials

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.

Material options

Plastic injection molding is a versatile process, with the ability to handle an extremely wide range of materials. RevPart is ready with the expertise to match materials and formulations to your product needs.


Pantone matching for any color. Multiple color parts available via two-shot molding, overmolding, and insert molding. 


Capabilities to texture the mold according to any SPI finish or MT finish. The repeatability of plastic injection molding ensures consistency, even for detailed finishes. 


Achieve various specific qualities for your part through resin selection, including durometer, flexibility and more. Potential for food grade, medical grade and other specialty parts. 

Value added options:

Fulfill other requirements beyond plastic injection molding, including spray painting of parts, pad printing, screen printing and more.


Q: Should I choose plastic molding for my product?

A: Plastic molding is an excellent choice for your product if it requires high precision with tight tolerances and if a high degree of repeatability is an important concern. Plastic molding also offers fast, efficient production speeds once the tooling for the product has been created (which may require some lead time), a low cost per part and a wide range of material choices.


Q: What kind of certification should I look for in a plastic molder?

A: Certifications mean that a manufacturer has made the effort and investment to ensure that their processes and services meet the highest standards in the industry. In a commodity field such as plastic molding, certifications can be one of the best gauges of the service and quality that you can expect to receive from your chosen supplier. Some key certifications to look for include ISO and TS certifications, including certifications specific to the industry in which you operate.


Q: Why use injection molding?

A: Injection molding offers a number of advantages in the right scenarios. The process offers one of the lowest costs per part, even for lower volumes. In fact, with the right mold material, low-volume plastic injection molding is just as cost-effective as competing processes. Injection molding also offers a broad, diverse range of material choices with different material properties to suit your application, and it is one of the fastest and most efficient processes available.


Q: How do I choose the right resin for my parts?

A: The right resin for your part will be dictated by the product’s application and requirements. While you will often have an idea of the right resin, especially once you become familiar with the options available, it is always a good idea to consult with an expert in the field to ensure the right choice for your part. Resins are generally broken down into amorphous and semicrystalline types, with numerous options available in each category. Factors to consider include environmental resistance needs (heat and cold), strength, flexibility, hardness, material resistance, special requirements (for example, food grade) and anything else unique to your product.


Q: What secondary services are offered on my injection molded product?

A: RevPart offers a wide selection of secondary services for your injection molded product, including CNC machining, CNC milling, CNC turning, short-run molding and more. Our expertise in these areas help make us a true one-stop shop for your molding needs.
