Product Description
Advanced Manufacturing Process
⚙️ 1. Composite Casting Technology
Our composite casting method uses more than one metal to make parts stronger and more resistant to wear. This makes sure that parts like engine mounts and transmission parts can handle harsh conditions in cars.
📐 2. Custom Mold & Wax Pattern Forming
• Custom molds are CNC-machined to client specifications, achieving ±0.05mm dimensional accuracy.
• Wax patterns are injection-formed for complex geometries, enabling near-net-shape blanks with minimal material waste.
🔬 3. Precision CNC Machining & Inspection
Post-casting, each part undergoes CNC machining to meet exact tolerances (ISO 2768 Fine). Critical dimensions are verified via CMM and optical comparators.
🛡️ 4. Assembly, Welding & Zinc Plating
• Robotic welding ensures consistent joint strength (AWS D1.1 certified).
• Electrolytic zinc plating provides >500 hours of salt spray resistance (ASTM B633).
✅ 5. Quality Assurance
• Material Testing: Spectrometer-verified alloy composition.
• Dimensional Checks: 100% post-machining inspection.
• Performance Validation: Fatigue testing (10⁶ cycles at 150% load).
