What is POM Injection Molding?
POM (Polyoxymethylene), known as acetal or Delrin®, is an engineering thermoplastic prized for its exceptional mechanical properties:
● Strength & Stiffness: 30% higher tensile strength stiffness than nylon
● Creep Resistance: Maintains shape under sustained mechanical stresses
● Minimal Friction: Inherent lubrication for bearing and gear applications
● Exceptional Dimensional Integrity: Maintains ±0.02mm tolerances under high humidity
As POM is a high-performance polymer, it requires precise temperature control during plastic injection molding to achieve optimal crystallinity. This ensures high-quality parts with consistent material properties for demanding applications.
Industries & Applications
Automotive
● Fuel caps, seatbelt mechanisms
● Leveraging POM’s creep resistance under hood temperatures
Electronics
● Connector housings, SIM card trays
● Utilizing electrical insulation properties
Industrial
● Bearings, valve seats, conveyor guides
● Exploiting stiffness low friction for maintenance-free operation
Consumer Goods
● Zipper teeth, appliance gears
● Benefiting from FDA-compliant POM plastics

Frequently Asked Questions
Q: What’s your MOQ for production?
A: Standard MOQ is 1,000pcs; prototypes doesn’t have MOQ.
Q: How long for mold fabrication?
A: 15-25 days depending on complexity.
Q: Can POM parts be colored?
A: Yes – we match Pantone codes with UV-stable masterbatches.
Q: Why POM Outperforms Alternatives
POM’s unique combination of mechanical strength, creep resistance, and stiffness low friction makes it ideal for dynamic load applications. Unlike nylon, it won’t absorb moisture and swell – critical for assemblies like precision gears where dimensional stability is paramount.
Q: POM vs. Competing Materials
