Dupont Delrin is the perfect plastic for turning on a CNC lathe lathe. It is easy to turn, but it does require slower speeds. I have used this material to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. The small parts usually ship quickly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, and they have very similar physical properties. They do look similar, but in practical uses there are some differences that can make one preferable than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,giving an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, durability and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in moisture applications. This environment suits acetal well because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
