Nylon
Nylon is a semi-crystalline engineering plastic for wear-resistant and load-bearing components.
Define the fit in the conditions where it will be used
A nylon sleeve or locating component needs a material choice that fits its working environment. Aria helps you discuss the grade, reinforcement and moisture conditions alongside the dimensions that control assembly. Keep dry and conditioned property values separate when comparing options, and agree which condition your dimensional requirements refer to.
Aria offers machining, molding and nylon printing options. You can compare the route for a trial component with the route for repeat parts, keeping the grade and test conditions explicit at each stage.

Selection requirements
- CNC Milling Services
CNC Milling Services: Injection molding after drying; CNC milling and turning of cast nylon sheet or rod. Keep dry and conditioned test values separate. Account for moisture expansion in precision fits. The supplied molding guidance calls for moisture at or below 0.15%. Glass reinforcement changes flow-direction shrinkage and mechanical performance. 3-axis milling, 4-axis milling, 5-axis milling: Use a machinable stock grade; geometry, workholding and material condition determine feasibility.
- Injection molding
Injection molding: Injection molding after drying; CNC milling and turning of cast nylon sheet or rod. Keep dry and conditioned test values separate. Account for moisture expansion in precision fits. The supplied molding guidance calls for moisture at or below 0.15%. Glass reinforcement changes flow-direction shrinkage and mechanical performance. Single-material injection molding, Insert location and retention, Multi-shot / two-shot (2K) molding: Use an injection-molding grade. Fillers, shrinkage and processing temperatures affect tool and part design. Elastomer over plastic, Plastic over plastic: Substrate and overmold are a grade-specific pair. These materials are candidates, not an all-to-all bonding guarantee; qualify adhesion and mechanical retention. Elastomer over metal, Plastic over metal: Metal is the insert or substrate; polymer is the molded layer. Review grade pairing, surface preparation, thermal movement and retention.
- 3D printing
FDM printing: Use a filament grade compatible with the printer and the intended loading direction; coating adhesion requires preparation. SLS printing: Use an SLS powder grade. Powder removal, surface texture and coating preparation affect the final part.
- Insert molding
Use an injection-molding grade. Fillers, shrinkage and processing temperatures affect tool and part design.

Advantages and considerations
Advantages
Good strength, stiffness, fatigue resistance, wear behavior and resistance to oils and many organic solvents. PA66 offers higher heat resistance than PA6; its melting point is around 260°C.
Material limitations
Moisture changes dimensions and mechanical properties. Dry material is less tough. Avoid strong acids and prolonged hot, wet conditions that promote hydrolysis.
How Aria supports your project
Help choosing a material
Compare materials for the loads, temperature and environment your part will face.
Design feedback before production
We review tool access, geometry and material choice before manufacturing.
Inspection to your drawing
Dimensional checks and inspection reports for the critical features on your drawing.
Compatible surface finishes
Selection requirements
- Painting · Pad printing · Silk screening
Adhesion depends on polymer grade, surface preparation and coating or ink chemistry. Confirm with the selected formulation.
- Glossy · Semi-glossy · Matt · Textured
Mold-transferred appearance depends on the resin and tool surface; gloss and texture do not specify a material-independent roughness.
Applications
Typical applications
Gears, bearings, slides, fasteners, automotive structural parts, power-tool parts and electrical connectors. Cast PA6 stock is also used for larger machined parts.
Design considerations
Processing options
Injection molding after drying; CNC milling and turning of cast nylon sheet or rod.
Finishing options
Dyeing and printing are possible. Painting and bonding need process qualification; electroplating normally requires a specialized process.
Grade and finish combinations
Keep dry and conditioned test values separate. Account for moisture expansion in precision fits. The supplied molding guidance calls for moisture at or below 0.15%. Glass reinforcement changes flow-direction shrinkage and mechanical performance.
Color and grade options
Natural milky white to pale yellow. Black and custom colors.
