Fighting Detects with Improved Gating - Four metalcasting firms overcame casting defects by augmenting the gating systems

摘要

They happen in almost every green sand facility. Inclusion defects, Although there are various ways such defects occur, they are known as the number one source of scrapped castings, One method to improve the defect rate is to focus on the gating system and look to how a slight augmentation to the system can eliminate inclusion errors, Four metalcasting facilities were faced with inclusion defect problems in their castings. However, altered gating systems allowed them to overcome their dilemmas, reduce scrap and improve production. This article details case studies from these green sand casting facilities and how problems were solved with gating.
