Material engineering
Why nylon is selected for mechanical parts
Nylon is a versatile engineering thermoplastic for components exposed to repetitive stress, mechanical loads, and friction. Its combination of strength, fatigue resistance, and low coefficient of friction supports long service life in functional assemblies.
01
Mechanical strength
Suitable for load-bearing and structural components that require dependable rigidity.
02
Wear resistance
Low friction and strong wear performance support gears, bushings, rollers, and bearings.
03
Fatigue resistance
A practical choice for components exposed to repeated movement and cyclic stress.
Material selection
PA6 vs. PA66 material comparison
Choosing the correct grade is critical to the performance of injection-molded parts. Our team considers mechanical load, temperature, dimensional requirements, and end-use conditions during material selection.
| Property | PA6 (Polyamide 6) | PA66 (Polyamide 66) |
|---|---|---|
| Mechanical Strength | High | Higher |
| Stiffness / Rigidity | Good | Excellent |
| Wear Resistance | Excellent | Superior |
| Melting Point | ~220°C | ~260°C |
| Water Absorption | Higher | Lower |
| Primary Use | General engineering, gears | High-load, automotive, structural |
Production capability
From tooling strategy to stable production
Our facility supports unfilled nylon and fiber-reinforced grades, including glass-filled and mineral-filled materials, for components requiring increased structural rigidity.
Custom mold tooling
Prototype, bridge, and multi-cavity production molds using P20, 718, or H13 steel for long-term tool life.
Insert molding
Metal threaded inserts and terminals can be overmolded into PA housings for electronics and automotive applications.
Tolerance control
Standard tolerances of ±0.05 mm with process controls for the shrinkage of semi-crystalline PA.
Part range
Injection molding machines from 50 to 1,000 tons support parts from 1 g to 5 kg.
Industry applications
Functional nylon parts across demanding sectors
We support manufacturers who need reliable, long-lasting components with controlled friction, strength, and dimensional performance.
Automotive
Clips, brackets, fuel system components, and interior structural parts.
Industrial equipment
Gears, bearings, rollers, and bushings requiring low friction and wear resistance.
Electronics
Connectors, housings, and cable management components requiring high-temperature performance.
Robotics
Structural components and linkages that benefit from high strength-to-weight ratios.
Design support
DFM decisions that protect part quality
Successful nylon molding requires early attention to material behavior, cooling, ejection, and shrinkage. Our engineering team reviews every project for the following factors.
Secondary processing
Finished components, ready for integration
CNC machining
For features that cannot be molded or require tighter tolerances.
Threaded insert installation
Ultrasonic or heat-staking installation for metal inserts.
Assembly
Full mechanical assembly of multi-part plastic units.
Surface finishing
Texture, polishing, and laser marking for branding or specifications.
