POM Delrin & Nylon PA6/PA66 Engineering Polymers

Low Friction, High Fatigue Endurance, Dimensional Rigidity & Silent Mechanical Motion.

POM (Polyoxymethylene / Acetal / Delrin) and Polyamide (Nylon PA6 / PA66 / PA12) are the workhorses of precision polymer engineering. Delrin exhibits high tensile strength, exceptional dimensional stability in wet environments, and low coefficient of friction against metals. Nylon provides outstanding shock absorption, extreme abrasion resistance, and silent operation in spur gears, roller guides, and conveyor bearings.

Material Engineering for POM Delrin & Nylon PA6/PA66 Engineering Polymers

Certified raw material sourcing, certified heat-treatment verification, and extreme tolerance manufacturing calibrated specifically for POM Delrin & Nylon PA6/PA66 Engineering Polymers components.

Zero Moisture Warpage (POM)

Acetal absorbs less than 0.2% moisture, maintaining pitch diameter tolerances within ±0.01mm in humid air.

Self-Lubricating Wear

Mated POM-to-steel gears operate smoothly without external oil lubrication, preventing contamination.

Glass-Filled Nylon (PA66-GF30)

30% glass fiber reinforcement doubles tensile stiffness and increases heat deflection temperature up to 250°C.

Cryogenic Precision Deburring

Cryogenic tumbling flash removal guarantees sharp tooth profiles and zero micro-hairs on precision gears.

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for POM Delrin & Nylon PA6/PA66 Engineering Polymers.

Should I choose Delrin or Nylon for my gears? +
Choose Delrin (POM) if the gear operates in a humid environment or requires tight dimensional accuracy with low water absorption. Choose Nylon if the gear experiences high shock loads.
Can Delrin be glued or painted? +
Due to its low surface energy and high chemical resistance, Delrin is extremely difficult to bond with standard adhesives. Parts are usually joined with snap fits or press pins.
What is the difference between Acetal Homopolymer and Copolymer? +
Homopolymer (Delrin) has higher tensile strength, stiffness, and fatigue life. Copolymer has superior resistance to hot water, alkaline hydrolysis, and center-line porosity.
What tolerance can you achieve on CNC machined plastic parts? +
On Delrin and stabilized polymers, we routinely hold ±0.01mm to ±0.02mm, measured in temperature-controlled 20°C inspection cleanrooms.
