KYLT daily work: Aluminium alloy chair arms production
The following is the core content of the "Aluminum Alloy Die Casting Defect Troubleshooting Manual":
1. Flow marks
2. Pattern marks
3. Cold shuts
4. Shrinkage depressions (sink marks)
5. Cracking (mesh-like fins)
6. Impressions (from ejector pins or parting lines)
Use hot-work tool steels such as H13 or SKD61, optimize gate location, and cooling channel layout.
Maintain proper die and molten metal temperature, optimize fill speed, and injection pressure.
Include trimming, deburring, tapping, and thermal straightening to meet assembly requirements.
→ May cause flow marks or cold shuts.
→ Leads to incomplete filling or cold shuts.
→ Results in shrinkage depressions.
→ Causes surface impressions.
→ Leads to cracking defects over time.
