Nylon (PA) is a high-performance engineering thermoplastic featuring superior tensile strength, abrasion resistance, and impact toughness, widely used for load-bearing mechanical components. Its unique hygroscopic property requires special design considerations for tight-tolerance projects. ## Nylon Common Grades for CNC Machining ### PA6 (Nylon 6) Superior flexibility and impact resistance, higher moisture absorption rate, cost-effective and widely stocked. Best choice for parts prioritizing shock resistance instead of strict dimensional stability. ### PA66 (Nylon 66) Higher rigidity, heat resistance up to 120℃ and lower water absorption. Default precision grade for dimension-critical structural machined components. ### Glass-filled PA6 / PA66-GF Glass fiber reinforcement improves stiffness and drastically reduces moisture swelling, ideal for tight tolerance parts working under varying ambient humidity, slightly poorer impact toughness. ### MoS₂ Filled Nylon Molybdenum disulfide additive enhances self-lubrication and wear performance, specially customized for sliding bearings and friction wear components. ## Key Advantages of Machined Nylon Parts ### Excellent Strength-to-Weight Higher mechanical strength than common ABS with much lighter weight than metal, perfect for lightweight structural brackets replacing aluminum/steel. ### Outstanding Fatigue & Toughness Absorb repeated impact and cyclic vibration without cracking, long service life for dynamically loaded mechanical assemblies. ### Great Wear & Abrasion Resistance Resist surface abrasion under continuous sliding friction, extend service lifespan for wear pads, guides and bushing inserts. ### Broad Chemical Compatibility Resist oils, fuels, greases and alkaline liquids, better alkali resistance than POM for fluid contacting mechanical parts. ### Stable CNC Machinability Clean cutting performance without specialized tooling, consistent finished dimension for milling, turning and tapping processes. ### Low Volume Cost Saving No expensive injection mold investment, affordable for prototypes and small-batch customized mechanical parts with quick CAD modification. ## Critical Design Point: Nylon Moisture Absorption Nylon is hygroscopic and expands when absorbing ambient moisture, leading to dimensional variation. PA6 saturates \~9\~10% weight moisture while PA66 \~7\~8%, glass-filled grades only 1\~3%. **Design Solutions:** * Select GF filled nylon for tight-tolerance parts in a changing humidity environment * Reserve assembly clearance to compensate for material expansion & shrinkage * Prefer PA66 over PA6 for dimension-sensitive finished products * Switch to low-hygroscopic POM if an ultra-stable dimension is mandatory We will remind all customers of moisture-related risks before production starts, as part of the quotation process. ![Nylon CNC machining parts5]() ## Our Nylon CNC Machining Capabilities ### Multi-axis CNC Milling Complex pocket, slot and contoured structural brackets from solid PA block with stable dimensional accuracy. ### Precision CNC Turning Bushings, rollers, spacers and threaded cylindrical nylon components with tight diameter tolerance control. ### Drilling & Custom Tapping Optimized drill size for nylon spring-back to avoid thread crack, blind hole & counterbore processing available. ### Single Prototype Machining One-off real PA material functional samples with actual mechanical properties, fast turnaround without MOQ limit. ### Low & Mid Batch Production Consistent batch quality without injection mold cost, suitable pre-mass-production verification parts. ### Complex Load-Bearing Geometry Multi-feature structural components with precision bearing seats and irregular load-bearing bores. ## Common CNC Machined Nylon Components ![Nylon Structural Mount Brackets]() ### Structural Mount Brackets Automotive & equipment load-bearing mounting plates taking advantage of nylon high strength-to-weight ratio. ![Nylon Wear Pads & Sliding Guides]() ### Wear Pads & Sliding Guides Abrasion resistant inserts protecting metal mating parts from long-term friction damage. ![Nylon Cable Conduit Guides]() ### Cable Conduit Guides Tough flexible wire routing parts resisting vibration crack in automotive wiring harness systems. ![Nylon Bushings & Plain Bearings]() ### Bushings & Plain Bearings Light-medium load sleeve inserts requiring higher impact resistance than standard POM bushings. ![Nylon Small Spur Gears & Drive Parts]() ### Small Spur Gears & Drive Parts Quiet running low-load gears for household appliances and small automation devices. ![Nylon Fluid Manifold & Valve Parts]() ### Fluid Manifold & Valve Parts Oil/fuel resistant manifold blocks and small valve bodies for fluid control equipment. ## Nylon PA6 VS PA66 Typical Physical Properties | Material Property | PA6 | PA66 | | ------------------------------ | ------------------------ | -------------------------------- | | Tensile Strength | 70\~80 MPa | 80\~90 MPa | | Flexural Modulus | 2500\~3000 MPa | 2800\~3300 MPa | | Continuous Working Temp | 90\~100℃ | 110\~120℃ | | Saturation Moisture Absorption | 9\~10% | 7\~8% | | Density | 1.13\~1.15 g/cm³ | 1.13\~1.15 g/cm³ | | Core Feature | High toughness, low cost | High stiffness, low water uptake | ## PEEK VS PEI VS PTFE Comparison | Item | PEEK | PEI(Ultem) | PTFE(Teflon) | | -------------------- | ------------------ | -------------------- | ----------------- | | Max Continuous Temp | 250℃ | 170℃ | 260℃ | | Mechanical Strength | Very High | High | Low | | Chemical Resistance | Excellent | Good | Best | | Friction Coefficient | Medium | Medium | Ultra Low | | Flammability | Self-extinguish | V0 Grade | Non-flammable | | Core Application | Med/Aero High Load | Flame Retardant Elec | Seal Gasket Parts | ## Key Design Guidelines for Nylon Machining ### Control Moisture Influence Reserve assembly clearance for humidity expansion; choose GF nylon for tight tolerance finished products. ### Minimum Wall Thickness ≥1.5mm Thinner walls easy deform during clamping & machining, mark thin-wall area on your drawing for process adjustment. ### Optimize Thread Drill Size Nylon thread springs back after tapping, adopt slightly larger pilot hole than standard metal tap specification. ### Inner Corner R≥0.5mm Avoid sharp inner corners to eliminate stress crack under cyclic mechanical load. ### Thermal Expansion Clearance Set assembly gap between nylon and metal parts to compensate different thermal expansion rate. ### Chemical Compatibility Check Nylon resistant to oil/alkali but damaged by strong acid, confirm working fluid environment before material selection. ## Tolerance & QC Standard General Tolerance: ±0.1 mm Precision Tolerance: Up to ±0.005 mm Every nylon piece is fully dimensionally inspected against the drawing before delivery, and FA inspection is available for bulk orders on request. ## Available Surface Finishes * **As-Machined:** Standard finish for most structural mechanical parts * **Fine Polishing:** Smooth surface for low-friction sliding contact faces * **Bead Blasting:** Uniform matte texture for visible aesthetic housings Note: Nylon is not suitable for regular painting/plating without special surface activation treatment. ## Main Industries We Supply ![Automotive Parts]() ### Automotive Parts Interior brackets, cable retainers and underhood fluid resistant components. ![Industrial Automation]() ### Industrial Automation Conveyor wear strips, cam followers and equipment structural inserts. ![Medical Device]() ### Medical Device Non-implant diagnostic equipment structural housings & mounting frames. ## Order Flow: From CAD Drawing To Finished Nylon Parts ## 1 ### Submit Your CAD Files Send STEP/IGES/DXF/DWG + 2D drawing with tolerance, finish and working environment info. ![Upload Your CAD File]() 2 ### Get Detailed Quote Within 24H Engineer recommend suitable nylon grade & list price, lead time and moisture design tips. ![Get a Quote in Hours]() 3 ### Confirm All Specifications Final confirm PA grade, tolerance and anti-humidity design before cutting starts. ![Precision Machining]() 4 ### CNC Machining & QC Inspection Machining → optional surface finish → full dimensional inspection per drawing. ![CNC Machining & Full QC]() 5 ### Global Shipment Standard 5\~15 working days delivery, express rush service available for urgent projects. ![Fast Shipping Worldwide]() [ Upload File ](#elementor-action%3Aaction%3Dpopup%3Aopen%26settings%3DeyJpZCI6IjYyMCIsInRvZ2dsZSI6ZmFsc2V9) ## Frequently Asked Questions #### Q: What is nylon CNC machining?
