Delrin is the best plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, although it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased many items from iPlastic. The smaller pieces usually ship quickly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, as they have similar physical properties. They look similar, but in practical uses there are some differences that may make one preferable than the other. It also depends heavily on your application. As with any 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 best material for machining,giving an great finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which aid 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 delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in moisture applications. This environment suits acetal well because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
