How Can SigmaPro Add Value To Your Manufacturing?

Best-in-class equipment

SigmaPro uses both Electric and Electric hybrid machines, allowing us to hold molded part tolerances of .0001” on a consistent basis.

Additional Services

In addition to our standard molding operation, we offer the option of having your parts run in a Class 100k or ISO Class 8 cleanroom.


Customer requirements have challenged us to run some of the toughest materials on the market, like PEEK, Ultem, glass- filled Ultem, up to 30% stainless steel-filled materials in addition to PP, PE, and PC. Our ability to process these high-end materials allows for more options when starting a new project.

Certified Master Molders

SigmaPro’s team includes Process Engineers who have completed RJG’s Master Molder II. By implementing a scientific molding approach to each project, we are able to identify and correct potential problems early in the process, thus minimizing waste and reducing your time to market.

We’d love to talk more about your challenges and how we can be part of your manufacturing team.
