Renovation Of Cooler Production Line Based On Lean Thinking

Since the seventies, Japan’s Toyota created the Toyota production mode (also known as Lean Production Mode), nowadays one of lean production has become a mainstream mode of production. In order to achieve the purpose of lowing costs, improving product quality and shortening the delivery time, lean production sets customer demands as the starting point and devotes to eliminate all applications which can’t add values for customers as well as all waste,so that they can march to zero defects, zero inventory.Reducing the cost is the first magic weapon of enterprise survival, it helps enterprises get rid of today’s financial crisis as well as the excess capacity and the difficulty of global market competition. Lean production is recognized as one of the most scientific and competitive production modes in the world today.It represents the tendency of current manufacturing industry and is know as the standard production model of21st century manufacturing industry.Lean production management model has become a remedy for China’s enterprises to win a good business for the benefit and sustainable development.Nantong Jianghua thermodynamic machinery company mainly produces automotive power steering system, all of which products are all exported to Europe, America, Australia and Japan, etc. Company has achieved good social and economic benefits with annual sales of61.58million yuan.The paper adopts the monographic study as the writing style.First of all, through the introduction of the status quo of the development of Chinese manufacturing industries and the difficulties they are facing, putting forward in the theme of the paper, that is applying the lean production mode to solve the problems existing in the production line in thermodynamic machinery company. Secondly, the paper makes a simple introduction of the lean production theory and the theory of industrial engineering method used in the production line,and then makes a comprehensive and objective analysis of the basic situation of thermodynamic production line as well as production operation condition in order to find out the problems hiding in its online body balance, homework, logistics and on-site management In accordance with the ethical method provided in the lean production theory,the paper presents a concrete design plan for the modification of the production line and anticipates its implementation,at the same time analyzes the feasibility of implementing lean production scheme in thermodynamic production line. On this basis, starting from introducing the theory of lean,with applying integrated the related technologies and methods, makes a specific transformation in the thermodynamic field management, machining production line improvement, painting production line automated improvement, improving product quality and standard operating procedure,and makes concrete implementation steps of planning scheme.During the process eliminating production waste and non-value work, reducing the fraction defective products, shortening the production cycle, the company improves the production efficiency. Finally, on the effective analysis of thermodynamic production line after the implementation of lean production, and summarizes the experiences and lessons in this lean improvement. In the future of the company comprehensively implement the lean production mode provides a guidance and reference. In addition, the research results in the paper and corporate practice experience or lessons also provides certain reference significance for the same type manufacturing enterprises in China to apply lean production to improve production efficiency and improve management level.
