Yuchai casting scrap rate before November fell 25%

Since the beginning of this year, Yuchai casting factory continued to further promote lean manufacturing, and strengthen the management of production, and strictly control the quality of castings, 11 month before the reject rate was 1.4%, down 25%, reached the international advanced level.

In order to reduce the rejection rate, explored the foundry, implement a series of measuresto promote quality improvement. Is the implementation of the standardization of operation, through the improvement of 68 lean projects and the development of each point, the formation of a certain standards, process specifications, and curing execution of quality documents. At the same time, improve the casting factory management system, build Casting Factory Lean quality management framework; in, effect examination, with lean management platform, week (month) of project evaluation, project special inspection, project on-site inspection, lean knowledge training, lean tools applications, such as the promotion of measures, and guide the lean project efficiently; the third is the application of lean tools, analysis of quality problems with the use, effective prevention measures are put forward.

Under the strict control of the quality of castings, reduce scrap rate, casting workshop of the factory also summed up some experience, such as casting a workshop for recurring quality problems and production problems, develop a clear specification, let technology division, sub models is responsible for, to prevent the occurrence of problems and form a good atmosphere of internal competition. Casting workshop implementation of waste sand hole explosion sand crap "," pouring waste products "three systems as a special control, simultaneous implementation of the quality management process control and quality improvement of simultaneous implementation, to achieve better results. Casting workshop four control points management methods in the implementation of quality process menu management and models, developed a key post inspection standards, strengthen the site inspection found problems in the process of.

Reduce the casting scrap rate is to improve the energy efficiency, an important way toreduce energy consumption. Uphold the principle of "green development, harmonious and win-win" is the core idea of Yuchai, has been on the road of green casting exploration, forward, continue to enterprise restructuring and upgrading to inject new vitality.
