| With rapid development of various technologies, the generation of new industries are getting more fast while the market share of traditional manufacturing industries are getting less. In order to maintain their continuous development and their competitive advantages under the background of the new market, traditional manufacturing industries are bound to make continuous innovation. And the innovation should not only be at the technical level but also be at the production model level. After great success of the thought of lean production of TOYOTA in Japan, lean production was soon introduced to many countries and became a production model pursued by manufacture industries all over the world. According to the current situation of our country, the theory of lean production is still applicable to the structural adjustment of China’s manufacturing industry.Based on WST company as the research object, this paper studied the application of lean production in the company of WST. Firstly, the origin and connotation of lean production are introduced as well as its implementation principle and effect, etc. Then, the WST company’s operating status is studied, and a series of current production issues of WST are analyzed in depth. It has been discovered that there are existing issues of WST’s production like unstable product quality and uncertain delivery time and so on. According to those existing issues, a set of lean production system is constructed and it is used on the project of "large size rod surface smoothness" of the cold machining workshop. Finally, the rate of finished products is improved, the raw material is saved and the production cost is compressed. The effect is proved to be great.Although lean production is not a new production method, it is still rare that full implementation of lean production in the traditional metallurgical enterprises in our country. Therefore, it is expected that this set of lean production system could be further enriched in company practice of WST, and at the same time, certain reference could be provided for the enterprises in the same industry on the implementation of lean production and lean management. |
