Child Seat Mold
Challenge: Large structural part requiring high impact resistance; variable wall thickness; must pass ECE R44/129 crash test standards.
Solution: Multi-gate sequential filling for stress-critical zones, gas-assisted injection for thick sections to reduce weight and sink marks, rib layout via FEA.
Result: Part weight reduced 12% via gas-assist, passed ECE R44/129 dynamic crash test, wall thickness variance under 3%.
