CNC Machined Plastic Parts

Tight-tolerance machined components from engineering-grade plastics — prototype quantities through production runs.

Precision plastic machining

When the part calls for tight tolerances, complex pocket geometry, or a material that doesn't form well, machining is the answer. We machine plastic stock — sheet, rod, and tube — in our mills, lathes, and CNC routers, with fixturing built to keep parts flat and dimensionally stable through the cut.

Send us a STEP, IGES, or PDF drawing and we'll quote off your file. If you only have a sample part to match, we'll reverse the geometry and quote from there.
