Dupont Delrin is the best plastic for turning on a CNC lathe lathe. It’s easy to turn, however it requires reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. The smaller parts always ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are exceptionally durable and easily machinable, as they have similar physical properties. They do look the same, but in practical use there are some differences that may make one better than the other. It also depends 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 primary material for machining,as it gives an great finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, hardness and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is especially valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the auto industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in moisture applications. This environment suits acetal well because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
