Quality Control Through Process Understanding: A system-wide, multi-pronged approach may add time to production but reduces more consequential losses

摘要

Developing a best-in-class quality-control program demands a thorough understanding of processes, both in the methods and practices set by an operation's managers and in the minds of the metalcasting workers. To obtain the highest levels of quality control, it is important for modern foundries to be as well-organized as possible, and developing a complete quality-control plan is the bedrock of any such endeavor. Regular testing remains the cornerstone of any thorough quality-control process, but this cannot be a random practice, nor one that is focused simply on products exiting a production line. A company's quality-control plan should explain exactly each step involved in the process, and the frequency with which it should take place, and define acceptable ranges of results. It also should set out the appropriate steps to be taken when a problem is identified.
