Delrin is the perfect plastic for turning on a CNC lathe lathe. It is very easy to turn, although it requires reduced speeds. I have used this material to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. The small parts always 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 quite tough and easily machinable, as they have similar physical properties. They do look similar, but for practical uses there are a few differences that may 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 probably our choice material for machining,giving an great finish both on manual and CNC Machines. Its got a very low moisture absorption making it the usual 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the auto industry because of its long term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in moisture applications. This environment suits acetal quite because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
