Acetal (Polyoxymethylene, POM) is a premier engineering thermoplastic renowned for its exceptional dimensional stability, high mechanical strength, and low-friction characteristics. Widely utilized as a metal replacement material, Acetal is ideal for components requiring tight tolerances, high stiffness, and smooth surface finishes. At AluCarbon Tech, we specialize in high-speed, multi-axis CNC machining of both Homopolymer (Delrin®) and Copolymer Acetal, delivering durable components for high-stress applications such as Sim Racing gear, drone parts, RC vehicle components, and industrial automation assemblies.
Why Choose AluCarbon Tech for Acetal / Delrin CNC Machining
Acetal materials are engineered for specific performance requirements. Selection depends on balancing structural properties, post-machining capabilities, thermal thresholds, and manufacturing costs. Choosing the right grade ensures optimal component performance and maximum manufacturing efficiency.
| Material Grade | Key Properties & Features | Typical Applications |
|---|---|---|
| Delrin® (Homopolymer POM) | Higher tensile strength, superior fatigue resistance, higher hardness, and lower wear rates compared to copolymer variants. | High-load gears, precision bearings, racing simulator shifters, wear strips, snap-fit assemblies. |
| Copolymer Acetal (POM-C) | Excellent chemical resistance, highly resistant to centerline porosity, optimal for hot-water applications and food-contact compliance. | Fuel system housings, food processing equipment, precision manifolds, custom industrial bushings. |
Self-lubricating pivot points, quick-release locking bushings, high-stress shifter guides, and noise-damping limiters.
Custom wear pads, low-friction roller bearings, actuator guide rails, and lightweight sensor brackets.
Fuel sensor modules, precision gear linkages, lightweight drone spacers, and RC car structural arms.
Non-conductive structural housings, circuit isolation blocks, and sterile handling components.
