Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, although it requires reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased many items from iPlastic. The small parts always ship quickly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly durable and easily machinable, and they have very comparable physical properties. They look the same, but in practical use there are a few 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 appropriate properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,as it gives an great finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it superb 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 automotive industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
