What we do.

Our CNC fabrication facility combines custom, three-axis CNC routing, five-axis CNC routing and secondary capabilities including cutting, bending, welding and assembly for a variety of custom product needs. The automated CNC process precision cuts components to regular and irregular shapes that can then be used by themselves, or made part of more complex assemblies.

CNC fabrication provides an economical solution for rapid turnaround of long and short runs of products fabricated from sheet plastic. Our machinists efficiently produce precision components from large stock up to 4 inch thickness, or as thin as 0.030.

In an effort to reduce lead times we utilize Master Cam Software to translate your part’s math data into the programming. Our 3 and 5 axis capabilities allow us to produce challenging product designs without the need for specialized tooling.
