Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s simple to turn, but it requires slower speeds. I have used this plastic to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Smaller pieces usually ship quickly and everything was well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, as they have very comparable physical properties. They do look similar, but for practical use there are a few differences that can make one preferable than the other. It also depends heavily on your application. As with any plastic materials, be sure to check the typical properties data sheet for the desired 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. Its got a very 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 many applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent 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 durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in boating applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
