Acetal (Delrin) CNC Machining Services

It’s important to ensure that your components can tolerate the physical and environmental demands of your application, which is why choosing the right plastic is so important. OEMs choose acetal for their custom-machined parts because it offers benefits like:

• Dimensional stability: Acetal is ideal for manufacturing precision parts because it’s an extremely stable material.
• Highly machinable: We’re able to cut acetal cleanly and smoothly with ease, and cuts will be smooth and precise.
• Moisture resistance: Like most thermoplastics, acetal is moisture resistant. It will hold up well when exposed to condensation, rain, or steam.
• Impact resistance: Overall, acetal is very durable and strong. That’s why we recommend it for applications requiring impact resistance.
• Temperature resistance: Acetal can withstand a temperature range of -40C to 120C, which is a much larger range than many plastics can tolerate.

In some situations, acetal can replace heavier metal parts, making your pieces significantly lighter weight and rust- and corrosion-resistant. 

Because of its moisture resistance, low friction, and overall durability, Delrin is commonly used to manufacture high-precision mechanical parts. Its dimensional stability and clean machining characteristics make it well suited for components requiring tight tolerances, smooth surface finishes, and consistent performance in moving assemblies.

With strong fatigue resistance and ability to maintain structural integrity under repeated mechanical stress, Acetal performs reliably in parts subjected to continuous motion and load.
