Good Plastic For Machining

Polishing methods are direct machine polish vapor polish flame polish and buffing.

Good plastic for machining.

We re looking for some hard plastic for some fixturing that will support some thin wall parts during machining. Their precision rigidity and power output allow them to process even hardened plastics with ease. Acetal peek and pvc plastic materials have superior machining characteristics plus they resist melting and chipping while offering good dimensional stability. Loading strength psi tensile strength plastic in tension and compression strength plastic under compression are important values for structural applications.

Plastic machining guidelines plastics generally allow for higher feed rates and create less wear and tear on machines and cutting bits as compared with metals. All the machine tools used to cut plastic are actually metal machining tools. We want something that handles threaded and or tapped holes nicely. I should note that woodworking machine tools won t do as good of a job though since their rigidity is lower.

3d printing is a more recent but rapidly maturing set of technologies opening up to a wider range of low to mid volume. Delrin is a good plastic for these or any other applications that will experience lots of friction require tight tolerances or need a high stiffness material. Plastic manufacturing processes are constantly evolving and the inflection points where it makes sense to move from one technique to another are shifting due to improvements in equipment materials and economies of scale. Our first thoughts are nylon.
