Delrin is the best plastic for turning on a CNC lathe lathe. It’s very easy to turn, but it requires slower speeds. I use this stuff to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. The smaller parts always ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very tough and easily machinable, as they have similar physical properties. They do look similar, but in practical uses there are a few differences that can make one better than the other. It also depends on your application. As with any plastic materials, be 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,giving 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 important. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous 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 and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the auto industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in water applications. This environment suits acetal quite because its low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
