Good Plastic For Machining

Their precision rigidity and power output allow them to process even hardened plastics with ease.

Good plastic for machining. 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. 3d printing is a more recent but rapidly maturing set of technologies opening up to a wider range of low to mid volume. We re looking for some hard plastic for some fixturing that will support some thin wall parts during machining. Our first thoughts are nylon.

Polishing methods are direct machine polish vapor polish flame polish and buffing. 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. Acetal peek and pvc plastic materials have superior machining characteristics plus they resist melting and chipping while offering good dimensional stability. 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. Acrylic clearest polycarbonate clear pvc polysulfone ultem. Loading strength psi tensile strength plastic in tension and compression strength plastic under compression are important values for structural applications.
