Why Plastic for Mechanical Parts
Advantages of Mechanical Plastic Parts Over Metal
Mechanical plastic parts offer distinct advantages over metal: self-lubrication eliminates the need for external grease, reducing maintenance costs. Lower weight improves energy efficiency in moving assemblies. Superior corrosion and chemical resistance extends service life in harsh environments. Plastics absorb vibration and reduce noise — critical for consumer-facing equipment. Our CNC-machined components in POM, Nylon, and PEEK deliver the precision of metal parts with the inherent benefits of engineering thermoplastics. Reference: Machine Design Magazine.
Materials for Industrial and General Applications
POM (Delrin)
The workhorse of mechanical plastic parts. Excellent wear resistance, low friction, and dimensional stability. Ideal for gears, bearings, bushings, and sliding components. Available in homopolymer and copolymer grades.
Nylon (PA6/66/12)
Tough, impact-resistant material for mechanical plastic parts under load. Good wear properties and noise dampening. PA12 for dimensionally stable applications. Glass-filled grades for increased strength and rigidity.
UHMW-PE & HDPE
Exceptional abrasion resistance for wear pads, chain guides, and conveyor components. Self-lubricating with very low coefficient of friction. FDA-compliant grades for food processing equipment.
PEEK, ABS & More
PEEK for high-temperature mechanical plastic parts to 480 F. ABS for cost-effective housings and covers. Polycarbonate for transparent guards and windows.
