Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It is very easy to turn, but it does require slower speeds. I have used this material to make Scottish small pipes chanters. I have ordered numerous items from a plastic shop in Anaheim. The smaller pieces 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 quite durable and easily machinable, as they have similar physical properties. They appear the same, but for practical uses there are some differences that can make one preferable 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 best material for machining,giving an great finish both on manual and CNC Machines. It has a very low moisture absorption making it the usual 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 excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is especially of value 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 help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics chosen within the auto industry because of its long lasting dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in marine 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.
