CNC Plastic Machining

We are Custom Cutting Technologies, Inc. Founded in 1999, we are a machine shop specializing in plastic materials. We operate several different types of CNC controlled equipment to maximize the services we can offer.

Our multi-head CNC routers are capable of efficiently and accurately machining parts from sheet stock. By running multiple parts under multiple heads, we can achieve part costs that you would expect from die cutting with quality that you would expect from machining or water jet cutting.

ISO 9001:2000 certified.
