Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, but it requires reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased many items from Industrial Plastic. The smaller parts always ship quickly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, as they have very comparable physical properties. They appear similar, but in practical uses there are some differences that may make one better than the other. It also depends heavily on your application. As with all plastic materials, be 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 great 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 perfect combination of high mechanical strength, hardness and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long lasting dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
