Nylon PA46
CNC Machining
Services
Precision CNC machining for Nylon 46 (PA46) components — from prototypes to repeat production. We help OEMs and engineering teams turn drawings and 3D models into reliable, high-performance PA46 parts with tight tolerances, consistent quality, and export-ready service from Dongguan, China.
Exceptional Heat & Wear Performance
Nylon PA46 (Stanyl) is a high-crystallinity polyamide with outstanding heat resistance, strength, and wear performance versus standard nylons — ideal when PA6/PA66 cannot meet elevated temperature or long-term dimensional stability requirements.
+ Key Advantages
- High temperature capability: Higher melting point and HDT than PA66; retains stiffness at elevated temperatures
- Good dimensional stability: Lower creep and better property retention under heat load than standard nylons
- Excellent wear & low friction: Suitable for gears, bushings, cams, and sliding elements
- Chemical resistance: Good resistance to oils, greases, fuels, and many hydrocarbons
- Moisture behavior: Absorbs less moisture than PA6, improving dimensional stability
- Cost-performance: Significantly lower cost than PEEK for high-temp, wear-critical parts
! Considerations
- 1 Stock shapes (rod/plate) are less common than PA6/PA66 — check lead times early
- 2 Notch sensitivity and brittleness in dry condition require sharp tools and controlled machining
- 3 Moisture and conditioning can influence dimensions — plan tolerances accordingly
- 4 Not ideal for hot-water/steam environments; consider PPSU/PEEK/PEI for continuous hydrothermal exposure

Stability Notes
PA46 absorbs some moisture over time; dimensions can shift from dry-as-machined to equilibrium. Options:
- Machine and ship dry-as-machined
- Pre-condition at 23°C/50% RH and measure at equilibrium
- Add humidity barrier packaging with desiccants
Design-for-Machining for PA46
Optimize your PA46 parts for manufacturability and performance.
Radii & Edges
Avoid sharp internal corners; use 0.5-1.0 mm fillets. Provide edge breaks (0.2-0.5 mm chamfer) to reduce chipping.
Wall Thickness
Keep walls ≥1.5-2.0 mm where possible; use ribs to reinforce instead of ultra-thin walls.
Gears & Wear Parts
Consider lubricated or GF grades; specify intended lubrication or dry-run conditions.
