HAI
HAI I READ YOU FACE PROBLEM
I SUGGESTED FROM MY EXPERIENCE
1. IF YOU USE GRAVITY DIECASTIN PROCESS
GOOD HEAT DIE AFTER SPRAY THE DIECOAT 34 FROM FOSECO, OR DYCOTE 140 MAY BE AVOID INTERNAL SHRINKAGE
2. PROPER VENTILATED AIR
3. GIVE MORE WIDTH OF RUNNER AND RISER
4.USE ONLY COLD METTAL 730 DEGREE CENTIGRADE
