Toughness
Supports functional clips, guards, and mechanisms that need more resilience than brittle prototype materials.
Plastic material
Nylon Manufacturing and Custom Parts
A tough engineering plastic used for gears, clips, structural parts, and functional prototypes.
- Tough
- Wear resistant
- Low density
Material overview
Tough functional parts across molding, machining, and powder-bed printing.
Nylon materials are used for gears, clips, manifolds, guides, and structural plastic parts that need toughness, wear behavior, and lower mass than metal. Different nylon families and reinforcements can produce substantially different stiffness, moisture response, and processing behavior.
Kewei reviews whether injection molding, stock-shape machining, SLS, or MJF best fits the geometry and volume. The page describes the material family; the exact PA grade belongs in the drawing and quotation package.
Key properties
Performance characteristics translated into manufacturing decisions.

Often considered for gears and sliding components after load, speed, and moisture are reviewed.
Process range
Available across molded, machined, and powder-bed printed routes with different surface and accuracy outcomes.
Reinforcement options
Filled grades can increase stiffness but also affect flow, surface appearance, tooling wear, and anisotropy.

Design considerations
Control the features that affect function and process stability.
G 01
Define the exact PA family and reinforcement.
G 02
Allow for moisture and temperature in precision fits.
G 03
Choose wall and rib geometry for the selected process.
G 04
Identify sealing, sliding, and cosmetic surfaces separately.
Limitations
Requirements that need engineering review.
- Moisture absorption can alter dimensions and mechanical behavior.
- Printed parts can be direction-dependent and more porous than molded parts.
- Glass-filled grades can show fibers and increase tool or mold wear.
- Tight fits require conditioning and inspection state to be agreed.
RFQ checklist
Material details to include in the quotation package.
Clear requirements help engineering, finishing, inspection, and purchasing review the same target.
- 01State the nylon family, reinforcement, color, and conditioning requirement.
- 02Printed nylon is not automatically equivalent to injection-molded or machined stock material.
- 03Moisture condition should be considered when dimensional checks are sensitive.

FAQ
Nylon questions from engineering and sourcing teams.
Is SLS nylon the same as injection-molded nylon?
No. They may share a polymer family, but processing, porosity, surface, directionality, and available grades differ. Qualification should match the intended production route.
Why does moisture matter for nylon parts?
Nylon can absorb moisture, which may change dimensions and mechanical behavior. Conditioning and inspection state should be defined for critical fits.
Can nylon gears be prototyped before molding?
Yes. Machining or additive manufacturing can support geometry and assembly evaluation, but performance may not exactly reproduce the final molded grade and fiber orientation.
