Polyimide machining

Machined Polyimide finished parts from Ensinger

In addition to the production of stock shapes and direct formed parts, polyimide materials are easy to machine. Complex components with tight tolerances can be produced on standard milling machines and lathes. Special plastic milling cutters should be used for optimum results. Polyimide materials from Ensinger (TECASINT) can be machined dry or with coolant if required. As machining is very similar to aluminium, the same carbide cutting tools can be used to machine TECASINT.
