Challenge
US client Manufacturing a complex coupler head with critical applications, including 6mm wall thickness in some areas, design led to shrinkage, cracks, and sand fusion issues.
our solution
• Increased radius in critical areas to eliminate cracks
• Used connective pads and ND risers to minimize shrinkage
Outcome
•Rejection Rate Reduced: From 7% to 2%
• Improved Durability: Extended part life for demanding locomotive applications
• Optimized Performance: Delivered a defect-free, high-quality casting for critical operations
