Nylon PA12 CNC Machining
Precision CNC machining of Nylon PA12 (Polyamide 12) parts — prototypes and low-volume production. Material guidance, tight tolerances, and export-focused service for global industrial applications.
Why Choose Nylon PA12 for Machined Parts
Lower Moisture Absorption
Better dimensional stability than PA6/PA66, ideal for environments sensitive to swelling or warping.
Chemical Resistance
Resistant to hydrocarbons, oils, fuels, and many solvents — suited for demanding fluid-handling applications.
Low Friction & Wear
Excellent sliding and wear performance for bushings, bearings, guide rails, and gear applications.
Impact Resistance
Good toughness with relatively low density, offering durability without excessive weight.
Electrical Insulation
Suitable for many industrial environments requiring non-conductive parts.
Grade Versatility
Unfilled, glass-filled, wear-modified, antistatic, and conductive grades available to match your requirements.

- • Spacers, shims, washers, structural insulators
- • Housings, covers, manifolds, fluid-handling components
- • Custom jigs, fixtures, nests, and tooling aids
- • Precision inserts, valve seats, seals, and low-friction components
Industries We Serve
Our PA12 CNC Machining Capabilities
From CNC milling and turning to complex pocketing, undercuts, and precision finishing — we support prototype builds through repeat production with comprehensive material guidance.
CNC Milling & Turning
Full 3-axis and 4-axis milling, multi-axis turning, drilling, tapping, threading, and slotting.
Complex Geometries
Pockets, undercuts, precision contours, and tight internal features with stable fixturing.
Material Guidance
Unfilled PA12, glass-filled, wear-modified, antistatic, and conductive grades reviewed per your application.
Tight Tolerances
Typical ±0.05–0.10mm; tighter ±0.02mm achievable on simple geometries with stable fixturing.
Surface Finishing
As-machined Ra 1.6–3.2μm; finer finishes with optimized tooling. Deburring, chamfers, edge conditioning included.
Prototype to Production
Seamless transition from prototypes to low-volume and repeat production with consistent quality.
Tolerances & Surface Finish
- • Typical dimensional tolerance: ±0.05–0.10 mm for many PA12 features
- • Tighter down to ±0.02–0.03 mm on simple geometries with stable fixturing
- • Flatness, perpendicularity, and concentricity controlled per drawing
- • As-machined surface finish typically Ra 1.6–3.2 μm; finer achievable
- • Deburring, edge conditioning, chamfers, and thread quality checks included
Achievable tolerances depend on part size, geometry, wall thickness, and PA12 grade. Confirmed during DFM review.
Recommended PA12 Grades
- • Standard extruded PA12 rod/plate for general-purpose
- • Glass-fiber-reinforced PA12 for improved stiffness
- • Wear-modified / lubricated (e.g., MoS₂-enhanced) for lower friction
- • Antistatic or conductive PA12 for ESD-sensitive environments
- • Flame-retardant grades for special compliance
Our engineers can recommend the optimal grade for your performance, budget, and availability requirements.
Design & Machining Guidelines for PA12
Optimize your part design for precision, stability, and cost-effectiveness with these guidelines.
Drying & Conditioning
Pre-dry PA12 material when needed to improve dimensional stability and surface finish.
Wall Thickness
Avoid ultra-thin walls; balanced wall sections reduce deflection.
Fillets & Radii
Use generous internal fillets to reduce stress concentration and improve toolpath stability.
Threads & Tapping
Use sharp tools and appropriate speeds; consider metal inserts for highly loaded threads.
Holes & Slots
Maintain adequate edge distances to prevent creep or distortion.
Fixturing & Stress
Use stable clamping; consider stress-relief steps for critical parts.
Moisture Management
Store and ship PA12 parts in sealed packaging when dimensional stability is critical.

Nylon PA12 vs Other Plastics
Quick comparison of key differences to help you select the right material.
| Material | Advantages over PA12 | Disadvantages vs PA12 |
|---|---|---|
| PA6 / PA66 | Higher stiffness in dry conditions | Higher moisture uptake, poorer dimensional stability |
| POM (Acetal) | Superior dimensional stability and wear resistance | Lower chemical resistance to hydrocarbons; less toughness |
| UHMW-PE / PTFE | Very low friction | Softer, difficult to hold tight tolerances; lower strength |
| PEEK / PEI | Higher temperature and chemical resistance | Significantly higher cost; use PA12 for mid-range budget-friendly performance |
