Gravity Casting and Die Casting Processes
We have an excellent technical team, which can be designed according to customers requirements.
1. Requirement Co-design
DFM Drives Zero-Defect Starting Point
Engineers provide die-casting-specific DFM solutions through 1v1 3D drawing analysis:
Optimize draft angles/wall thickness/ribs —— Reduce shrinkage risk by 30% Intelligent simulation of metal flow —— Predict porosity location, extend mold life by 50%
2. Intelligent Die-Casting Programming
Dynamic Parameters for Precise Form Control
Cloud-based die-casting platform calculates optimal process chain in real-time:
Three-stage injection control: Slow-speed 0.3m/s degassing → High-speed 6m/s filling → Intensification 100MPa feeding Precise mold temperature zoning ±5℃ —— Eliminate flow marks/cold shuts
3. Ultra-Clean Preprocessing
Dual Safeguards for Quality Assurance
Alloy melt purification:
Argon degassing + density testing —— Hydrogen content ≤0.1ml/100g
Intelligent mold maintenance:
Automated nano-coating spray → Laser-calibrated mold temperature → Mold clamping gap <0.03mm
4. High-Pressure Precision Forming
10,000-Tonne Integrated Die-Casting
Fully automated die-casting island execution:
1200℃ molten metal injected in 3s → 1200T clamping force maintains form → Water-cooling system rapid cooling Micron-level precision control: Thin-walled parts ±0.15mm tolerance | Surface Ra1.6μm no grinding required
5. Full-Dimension Quality Inspection
X-ray + CMM Dual Assurance
Internal defect scanning:
Industrial CT layered detection —— Porosity identification accuracy 0.2mm³
Zero-tolerance dimensional control:
Online CMM measurement → 100% key dimension comparison → Automatic machine lock for 0.05mm deviation
6. Value-Added Post-Processing
Functional & Aesthetic Dual Enhancement
One-stop surface solutions:
High-gloss diamond cutting → Nano-electroplating anti-corrosion (salt spray test 1000h+)
Medical-grade passivation | Custom color anodizing
