Nylon (PA)
Injection Molding | Excellent mechanical properties, chemical resistance, abrasion resistance
Introduction
PA (Nylon), a popular engineering plastic, is a synthetic polymer widely used due to its excellent mechanical properties, stiffness, toughness, shock absorption and resistance to wear.
Applications: Gears, bearings, thin-walled parts, screws, structural parts, pump parts, cameras.
Behavior: Nylon is very vulnerable to moisture, and can be more likely to suffer warping caused by a non-linear shrink.

Design Guideline
Wall Thickness
Between 1 mm and 3 mm
Keeping walls as thin and constant as possible will reduce warping and sinking
Thickness gradient
Wall thickness should increase by no more than three times
Transition between thicknesses can be made smoother with fillets
Internal edges
Rounded, more than half wall thickness
Add fillet with largest possible radius
External edges
Rounded, full wall thickness plus internal fillet
Add fillet with largest possible radius
Draft angle
Increase draft by 1° for every 25 mm (for parts taller than 50 mm)
Add draft to ease ejection and avoid drag marks
Textured finish
Increase draft angle by 1-2°
Increase draft to ease ejection and avoid drag marks
