Dupont Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s simple to turn, but it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have ordered numerous items from Industrial Plastic. The smaller pieces usually ship promptly and everything was well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have very similar physical properties. They do appear similar, but for practical use there are some 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 primary material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, durability and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses 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 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 used within the automotive industry because of its long term dimensional stability and durability. It delivers 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.
