Application of Quality Control Methods in Lowering Rejection Rate of Casting Products

摘要

Through analysis on some enterprise's main product, I find that there are most wasters in furnace tag. For the sake of ameliorating status quality, I use one method namely Pareto Diagram of quality tools to analyze and deal with data. Then the main quality vice can be identified well, we should set down the target value. To locate the critical factor of problem, Cause and Effect Diagram is applied to analyze man, machine, material, method, and environment and so on. Then, in the light the causes, formulate reasonable countermeasures and bring it into effect. After putting them into practice, pay close attention to the situation of the performance from time to time. The whole process is based on PDCA circles so as to make sure the process carried on successfully and put an end to these vices radically.
