POM (Polyoxymethylene), also known as Acetal or Delrin, is one of the most widely used engineering plastics in packaging equipment. Its low friction, excellent wear resistance, and dimensional stability make it ideal for conveyor components, guide rails, and moving parts that require long, maintenance-free service life. At QuikCNC, we precision-machine POM parts for all types of packaging machinery.
🔥 Key Properties
- Low Friction: Coefficient of friction comparable to PTFE in dry running conditions
- Wear Resistance: Excellent abrasion resistance for continuous sliding contact
- Dimensional Stability: Low moisture absorption ensures consistent part dimensions
- Machinability: Excellent chip formation and surface finish in CNC operations
- FDA Compliance: Select POM grades are FDA-compliant for dry food contact
- Fatigue Resistance: Good resistance to cyclic loading for spring clips and snap-fit parts
⚙️ Common POM Components
- Conveyor guide rails and wear strips
- Star wheels and timing screws for bottle handling
- Bearing bushings and cam followers
- Gears, sprockets, and pulleys
- Chain guides and tensioners
- Slide blocks and wear pads
- Custom profiles for product handling
