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

CNC Machined Aluminum
Aluminum is a relatively easy metal to machine which makes it great for CNC machining. Aluminum has useful properties for machining such as being lightweight, malleable, tractable and overall good durability. It being so light and easy to work with means that it can be used for a wide variety of applications. CNC machined Aluminum parts begin as a raw piece of metal which is cut down bit by bit to create a desired shape or object. This process is done most accurately with a CNC (Computerized Numerical Control) machine which can produce almost any three dimensional object designed via CAD (Computer Aided Design) software.
