Challenge
Cracks caused by thermal stress at the parting line junction
• Casting shrinkage and defects leading to leaks
• Increased fettling and rework time
our solution
Through advanced thermal stress analysis, we pinpointed design weaknesses and optimized the casting process:
• Added stress relief pads at critical parting line junctions to redistribute thermal stresses
• Incorporated riser chills to minimize shrinkage and prevent cracks
Outcome
• Defect-Free Casting: Eliminated leaks and structural weaknesses
• Improved Efficiency: Fettling time reduced by 60%
• Faster Lead Time: Enhanced production efficiency to meet on-time delivery (OTD) goals
• Performance Boost: Component durability and reliability improved by 25%
