Custom CNC machined nylon parts, PA6 machining service, PA66 precision components, non-standard nylon machining, engineering plastic CNC milling, custom nylon bushings
Nylon (Polyamide) serves as the primary engineering plastic for replacing metals like bronze, brass, aluminum, and stainless steel. Renowned for its superior mechanical strength, excellent wear resistance, low friction coefficient, and vibration damping, custom-machined nylon offers an exceptional performance-to-cost ratio. We specialize in non-standard precision CNC machining, supplying high-complexity PA6 and PA66 components tailored to international standards for OEM and Tier-1 clients worldwide.
Global Material Standards & Property Comparison
To meet strict international compliance and engineering specs, we source certified raw stocks accompanied by full material test reports (RoHS, REACH, FDA):
| Material Grade | ISO (Global) | ASTM (USA) | DIN (Germany) | JIS (Japan) | GB (China) | Key Properties & Ideal Applications |
| PA6 (Nylon 6) | ISO 1874-1 | ASTM D6779 / D4066 PA0110 | DIN EN ISO 1874-1 | JIS K 6920 | GB/T 12006.1 | Excellent impact resistance, high toughness, good low-temperature flexibility. Ideal for high-impact structural parts. |
| PA66 (Nylon 66) | ISO 1874-1 | ASTM D6779 / D4066 PA0210 | DIN EN ISO 1874-1 | JIS K 6920 | GB/T 12006.1 | Higher melting point, greater rigidity and hardness, superior wear resistance. Best for heavy-load dynamic components. |
| Modified Nylon (GF/MoS2/Oil) | ISO 16396 | ASTM D4066 (PA0120/PA0220) | DIN EN ISO 16396 | JIS K 6876 | GB/T 30568 | Reinforced with 30% Glass Fiber (PA6/66-GF30), MoS2, or solid lubricants for higher tensile strength and self-lubrication. |

Machining Capabilities & Process Control
Machining thermoplastics requires strict heat management to prevent part warping and surface burrs. We utilize specialized plastic-cutting tooling and stress-relief protocols to ensure tight tolerances:
-
3 / 4 / 5-Axis CNC Milling: Complex 3D geometries, pocketing, and multi-sided hole patterns maintained within ±0.02 mm tolerance.
-
CNC Turning & Mill-Turn: Precision shafting, threaded fittings, sleeves, and flanges produced in a single setup for optimal concentricity.
-
Threading & Tapping: Customized tool rake angles and chip breakers eliminate thread pulling, burring, or pitch expansion.
-
Stress-Relief Annealing: Intermediate heat treatment post-roughing eliminates internal stresses, preventing creep or dimensional drift in final assembly.
-
Finishing & Inspection: Manual/mechanical deburring, ultrasonic cleaning, laser marking, and 100% dimensional verification using Coordinate Measuring Machines (CMM).
