Nylon
Designers and engineers frequently choose aluminum and aluminum alloys for CNC machining and CNC milling parts. Makes sense. This all-purpose metal has been proven to offer:
- * Excellent machinability
- * High strength
- * Hardness
- * Heat tolerance
- * Corrosion resistance
- * Electrical conductivity
- * Low weight
- * Low cost
- * Overall versatility

Nylon Material Processing Technologies
| Processing Technology | Process Characteristics | Suitable Nylon Type | Applications |
|---|---|---|---|
| Injection Molding | Melt temperature 250-300°C, mold pressure 70-140 MPa | PA6, PA66, PA11, PA12, filled grades | Gears, bearings, automotive parts, electrical components |
| Extrusion | Melt temperature 230-290°C, screw design critical | PA6, PA66, GF-reinforced | Tubes, pipes, monofilaments, sheet materials |
| CNC Machining | High-speed milling (1200-2400 rpm), coolant required | Reinforced grades (GF30, GF50), PA46, MXD6 | Prototypes, custom parts, aerospace components |
| 3D Printing (FDM) | Nozzle temp 240-280°C, bed temp 80-100°C, layer 0.1-0.3mm | PA6, PA12, PA11 filaments | Functional prototypes, jigs, fixtures, end-use parts |
| Blow Molding | Parison temp 180-230°C, blowing pressure 0.4-1.0 MPa | Flexible grades (PA11, PA12), impact-modified | Fuel tanks, pneumatic tubes, fluid reservoirs |
| Thermoforming | Sheet heating 170-190°C, forming depth/width ratio <2:1 | PA6 sheets, transparent PA | Protective covers, food containers, electrical insulation |
Key Technical Notes
- Material Drying Required: All nylon grades require drying (80-90°C for 4-6 hours) before processing to prevent hydrolysis degradation
- Water Absorption Effects: Dimensions change up to 1-3% after moisture absorption; critical for precision components
- Glass Transition Temperatures: PA6: 50°C, PA66: 60°C, PA12: 40°C
- Reinforced Material Handling: Use carbide tools for glass-filled grades; mold steel hardness >52 HRC recommended
Processing Recommendations
- Melt temperature should be kept below 320°C to avoid thermal degradation
- For thin-wall parts, increase mold temperature to 80-100°C
- Minimum wall thickness varies by application: 0.5-1.0mm for electronics, 2-4mm for automotive
- Gate design should be at least 60-80% of part thickness for injection molding
Post-Processing & Quality Control
- Annealing: 160-180°C for 2-4 hours, slow cooling (30°C/hour) to reduce internal stresses
- Humidity Control: Store parts at 23°C, 50% RH for 48hrs before dimensional verification
- Adhesion Enhancement: Plasma treatment required for painting/printing on nylon surfaces
- Tolerance Guidelines: ISO 286 tolerance grades IT8-IT10 for injection molding
Aluminum Alloys for Machining
LML offers several aluminum alloys in its long list of available manufacturing materials. Two of those alloys are especially well-suited material options for CNC machining, whether milling or turning: Aluminum 6061 and 7075.Aluminum 7075 T651 and T7: Benefits include high strength, hardness, low weight, corrosion resistance, and high heat tolerance. See data sheet for more information.Aluminum 2024 T3: This high-strength alloy offers a high strength-to-weight ratio and high corrosion resistance. See data sheet for more information.GET INSTANT QUOTE
