Custom Acetal CNC Machining

At SR Machining, we specialize in precision acetal CNC machining services for custom components and assemblies. Known for its dimensional stability, low friction, and machinability, acetal is an excellent choice for a wide range of demanding applications.

Based in California, our team has years of experience machining acetal plastics, including Delrin® and Ertalyte®. Delrin is highly versatile and is known for its resistance to friction, abrasion, moisture, solvents, fuels, and fatigue. Ertalyte has high strength, extreme temperature tolerance, low water absorption, and resistance to acidic solutions. Our team can help determine the best acetal solution for your needs.

In addition to acetal, we work with a wide range of metal and plastic materials to create machined components that meet your needs. Together with our sister company, SR Plastics, we offer in-house injection molding services to provide you with complete manufacturing solutions. From standard to high-volume production runs, SR Machining supports your project with precision machining services.

Acetal CNC Machining Components and Applications

Acetal is a high-performance plastic with excellent machinability, dimensional stability, and surface finish. There are various types of acetal plastic, including Delrin and Ertalyte, each offering unique characteristics for specific requirements. In general, acetal plastics are valued for their low friction, wear resistance, and ability to maintain tight tolerances during precision machining.

At SR Machining, we machine both Delrin and Ertalyte to make custom plastic parts. Acetal components can include but are not limited to:

Gears and bushings
Manifolds
Rollers
Linear and journal bearings
Wear and slide pads
Valve seals
Thrust washers
Scraper blades
Fuel system pumps, connectors, and rotors
