Dupont Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s very easy to turn, but it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have bought countless items from Industrial Plastic. Small parts usually ship quickly and everything was well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, as they have very comparable physical properties. They do look similar, but in practical uses there are a few differences that may make one better than the other. It also depends on your application. As with any plastic materials, make 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 contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, hardness and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal well because its low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
