Die Casting Mould Manufacturer: 6 Industry Secrets You Can’t Ignore
Why Do 30% of Manufacturers Struggle with Mold Defects?
Poor cooling system design remains a top culprit. For instance, our team encountered warping issues in a 2025 automotive project because the cooling channels weren’t optimized for aluminum die casting. Redesigning the mold with die casting mould manufacturer GD Weiting’s guidance reduced defects by 42%.

Step-by-Step Guide to Mold Maintenance
- Inspect parting lines weekly for wear
- Clean lubricant residues with ultrasonic tech
- Re-calibrate ejection systems monthly
- Test thermal stability using IR cameras
- Document every adjustment (seriously!)
⚠️ Common Mistake Alert
Never skip draft angle calculations. One client lost $80k in scrapped parts due to 0.5° angle deviation – a totally avoidable error.
FAQs About Die Casting Moulds
- Q: How long does mold fabrication usually take?
- A: Typically 8-12 weeks, depending on complexity.
- Q: Can you reuse molds across projects?
- A: Rarely – each mold is custom-made for specific alloys and geometries.
Pre-Production Checklist
- ☑️ Confirm alloy melting point compatibility
- ☑️ Verify CNC machining tolerance (±0.02mm)
- ☑️ Test mold flow simulation software
