Perfect The Z Company Melting Workshop Product Quality Control Countermeasures

Z company is W company supply blank casting, casting in2013to reach an annualoutput of1200000pieces. It is a challenge for the production and quality control. Meltingshop of raw material quality control difficult, the normal production of melting shop hascertain influence. Cupola, induction furnace molten iron quality control measures are notproperly, resulting in hot metal composition qualified rate is not high, the influence of thecomposition of the casting stability. The chemical composition of casting traceability is notstrong, external quality problem tracing up larger workload. Tooling equipment can not meetthe needs of quality control, leading to the emergence of casting volume of waste. Qualityproblem processing unclear responsibility, quality flow of events is not clearly lead to occur.Product quality has always been the main problem melting workshop focus on Zcompany. However, the quality of the event is still frequent, quality management work stillneeds to be improved. The workshop on learning Toyota and mass in the process, often justlearning a way and method, and the true connotation not learn. Therefore, to refine on,persevere attitude to grasp the quality of management, and continuously strengthen thequality control process, improve the management level of product quality, it is still worth tostudy and explore. This is the article’s background.The thesis adopts the methods of observation, qualitative analysis, a comprehensivecompilation quality event melting workshop of Z company for a period of time since therecording, a detailed analysis of each link of the raw material inspection, production processquality control, production preparation and other quality responsibility system and otherfactors affecting the quality of the. Summarize the workshop quality management has thefollowing problems: the chemical composition of raw material of casting traceability is notstrong, cannot clear quality responsibility; raw materials inspection system is not perfect; theproduction process control link is not comprehensive, can not support the product liabilitysystem implementation; product liability system is not perfect, not the real implementationand other issues. Aiming at these problems, this paper puts forward perfect product liabilitysystem, improve the production process inspection, improve tooling equipment quality inspection, chemical composition of high casting back the countermeasures and so onseveral aspects of the.The above countermeasures through the implementation of a period of time, made someexpected effect, low probability level quality event occurred less, product quality has beenimproved obviously; the staff quality consciousness unceasing enhancement, the qualitymanagement level also gradually improve, provide a powerful guarantee for the developmentof enterprises.However, the workshop quality problems are still not the fundamental solution, theneed to continue to explore a better method of quality management in the future work.
