Custom Aluminum Extrusion Parts for Automotive Manufacturing
Service Process for Custom Aluminum Profiles
1. Initial Communication and Needs Analysis
Project Initiation: Client provides detailed product drawings, technical specifications, performance requirements (strength, tolerance, surface finish), environmental usage, and production forecasts.
Feasibility Assessment: Technical team reviews drawings to evaluate extrusion feasibility and provides optimization suggestions.
Material Selection: Recommended aluminum alloy grades (6061, 6063, or 6082) based on application requirements for strength and corrosion resistance.
2. Design and Die Development
Die Design: Engineers use specialized software to design dies ensuring dimensional accuracy and surface quality.
Die Manufacturing: High-precision extrusion dies manufactured through CNC machining with strict quality control.
3. Extrusion Production
Heating and Extrusion: Aluminum billets heated to 450-500°C and forced through dies with precise temperature and speed control.
Cooling and Straightening: Profiles quenched with air/water, then stretched and straightened to relieve internal stresses.
4. Post-Processing
- Precision Cutting: Profiles cut to specified lengths
- CNC Machining: Milling, drilling, and tapping to achieve complex shapes and tolerances
- Stamping and Bending: Forming required shapes
- Surface Treatment: Anodizing, powder coating, or painting for protection and aesthetics
5. Quality Control and Inspection
Throughout Monitoring: Strict quality control at every production stage
Dimensional Inspection: Precision instruments (calipers, CMMs) verify critical dimensions
Performance Testing: Hardness, tensile strength, and yield strength tests
6. Packaging and Delivery
Custom Packaging: Shock-proof and moisture-proof materials
Logistics Delivery: Timely delivery to client's designated location
