Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s very easy to turn, however it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Smaller parts usually ship promptly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have very similar physical properties. They do look similar, but for practical uses there are some differences that can make one better than the other. It also depends heavily on your application. As with all plastic materials, make sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,giving an nice finish both on manual and CNC Machines. Its got 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, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly valued 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 aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal quite because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
