Delrin is the best plastic for turning on a machine lathe. It’s very easy to turn, however it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought countless items from Industrial Plastic . Smaller pieces always ship promptly and everything has been well packed. I’ve never had an issue with an order. Between the Delrin and POM-C rods, both materials are quite durable and easily machinable, as they have very comparable physical properties. They do appear the same, but in practical uses there are some differences that can make one preferable than the other. It also depends on your application. As with any plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application. Our Acetal Sheet is probably our primary material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the preferred grade for food ...
