Application Research On BW Company Lean Production Site Improvements

After more than ten years of rapid growth, the growth rate of China’s auto market slowed down in recent years. In such an increasingly competitive market, consumer demand shift to diversification, high-quality, personalized aspects of the product, which means that manufacturing production company should Improve cost, efficiency and quality, in order to meet the higher requirements. Lean production is one way to enhance the core competitiveness of enterprises, as well as an important means to achieve competitive strategy.In Turbochargers increasingly competitive market, manufacturing labor costs are rising. For the turbocharger manufacturing enterprises, the traditional layout of production equipment, production management mode can not meet the production requirements of the lean production, so, how companies deal with the fierce competition in the market has put forward higher requirements. Auto parts enterprises are facing the comprehensive pressure of competition and cost efficiency. So, how to improve the site by generating lean improvement of production efficiency, reduce costs and improve product quality such enterprises become an urgent problem.In this paper, we take BW Ningbo company as the research object. Based on the analysis of turbocharger industry development, combined with the company’s future development strategy in the industry’s competitive situation, especially the competences research, we make a research on the company’s current manufacturing lean production improvement. Based on the analysis of the current situation of the manufacturing production, we found that in this companies, there are some problems of low productivity, high cost and long manufacturing cycle, high in-process inventory, safety and quality risks remains and so on. Furthermore, we found the cause of the above problems:the irrational production flow, unbalanced assembly line, on-site management confusion, high equipment failure rate. At last, we analyze the value stream, identify and implement lean manufacturing improvement goals and plans to study real cases.By implementing these measures, the company hopes to achieve the purpose of reducing security risks and manufacturing costs and inventory, improving product quality, increasing productivity, shorten production cycle, then to promote continuous improvement projects, as well as the company’s operating performance, and enhance core competitiveness, improve customer satisfaction.
