Nylon Material Properties

Key Properties of Machining-Grade Nylon

Typical room-temperature ranges for common unfilled PA6, PA66 and PA12 stock shapes.

Density 1.01–1.15 g/cm³
Tensile Strength 45–85 MPa
Tensile Modulus 1.4–3.5 GPa
Elongation at Break 20–200%
24-Hour Water Absorption 0.3–2.5%
Shore D Hardness 70–85

Values vary by polymer family, filler, conditioning state and test method. Final design values follow the selected supplier data sheet. See the PA material properties guide for a detailed comparison.

Manufacturing and Inspection

From Material Review to Final Inspection

Critical dimensions are checked after the part reaches a stable measurement condition.

01 · Material Review Confirm PA grade, stock form and conditioning state.
02 · Process Control Manage clamping force, cutting heat and dimensional movement.
03 · Dimensional Check Verify critical features at controlled temperature and condition.
04 · Delivery Control Clean, protect, label and pack approved parts.

Secondary operations: deburring · manual polishing · light blasting · laser marking · threaded inserts · assembly

Material Selection

When Should You Choose Machined Nylon?

Nylon is often selected for lightweight, low-friction and electrically insulating parts. Final selection should reflect load, temperature, humidity and dimensional requirements.

Choose Nylon When

  • Lower weight matters The part does not require metal-level stiffness.
  • Sliding or rotating contact is present Low friction and wear resistance support repeated motion.
  • Corrosion resistance is needed The component operates around moisture or compatible chemicals.
  • Electrical insulation is required The part must separate or protect electrical components.

Evaluate Another Material When

  • Continuous heat is high The service temperature exceeds the selected grade’s limit.
  • Structural stiffness is critical The part carries high sustained loads or must resist creep.
  • Humidity cannot be controlled Very tight dimensions must remain unchanged across environments.
  • Specific compliance is mandatory Flame, food, medical or chemical requirements need certified stock.

Nylon Machining FAQ

Plan Your Nylon Part

What is the best CNC bit for cutting nylon?

Use a sharp, polished carbide single- or two-flute cutter with positive rake and ample chip space. An O-flute or up-cut geometry clears chips and limits heat. Filled nylon requires more wear-resistant tooling.

What should be controlled when turning nylon rod?

Use light chuck pressure, short overhang and tailstock or steady-rest support for long stock. Sharp positive-rake tools, effective chip removal and controlled cutting heat reduce flex, chatter and melting.

How can the cost of custom nylon parts be reduced?

Choose available stock sizes, keep walls stable, use practical radii and reserve tight tolerances for functional features. Fewer setups and larger order quantities also reduce unit cost.

How do you ensure on-time delivery for custom nylon parts?

We confirm material availability, drawing requirements and the production route before fixing the schedule. Machining, secondary operations and inspection are tracked by milestone.
