Precision Machining of Custom Plastic Components

CNC Turning

PTFE CNC Turning 

A flanged sleeve bearing machined from Teflon™ PTFE receives a finishing pass.  APT efficiently machines parts like this by starting with an in-house compression molded PTFE tube in order to minimize material waste and reduce machining time.

CNC Turn-Mill Machining

The custom machined PTFE part above is having its bottom features rough machined. This is an example of a turn-milled part that is utilizing live milling in addition to CNC turning. 

Multi-Axis / 5-Axis Machining

Valve Body for Industrial CustomerExample - Custom Machined PTFE Part

Custom machined PTFE Valve Bodies and component for OEM customers.

APT's Mazak Integrex J-200 and Integrex 200-IV ST are excellent for turn-mill, multi-axis part production of Teflon™ PTFE and a variety of engineering plastics. Our CNC machines provide precision turning along with angular milling, drilling & tapping and are ready to machine your custom parts. The 200-IV ST has a 26 inch maximum machining diameter.
