Study On The Application Of Single Minute Exchange Of Die(SMED) In TM Spring Manufacturing Company

With the diversification of market demand and personalized, customer orders are becoming more and more varieties of small quantities, which means that the TM company’s production changeovers more often. TM company’s traditional mode of production changeovers longer, a serious waste of. In the full use of the existing resources of TM company, the implementation of SMED(Single Minute Exchange of Die), can improve the production efficiency, shorten the production cycle, reduce inventory, can improve the production capacity, can quickly respond to customer demand. SMED has important significance for TM company to broaden sources of income and reduce expenditure.Choose TM company spring models for the pilot, by using“program analysis”, “operation analysis”, “action analysis” IE analysis tool, using 5WHY, ECRS, PDCA analysis method, using “to distinguish between internal and external operation of production switch”, "internal operations into external industry", “shorten the operation time of internal”,“shorten the operation time of external” method step by the spring machine for mold tooling fixture modular, unified, standardized. Through the implementation of many parallel operations, on the production changeovers’ process implementation of standardized operation, realize shortening time for changeovers.Through the analysis of the Z products for the improvement of the process of the production changeovers, through the verification of the Z products, the time of the changeovers can be shortened by 40%-70%. Through the implementation of the fast production changeovers, changing the current spring machine for production changeovers to rely on the technology master experience, changing no standard condition for the method of adjusting machine. SMED is the focus of the implement and priority use of tools, methods in lean production. TM company’s SMED is the process of human nature, one purpose of SMED is in order to respect human nature, SMED in the implementation process also reflects the respect for human nature.TM company on the spring machine to implement the rapid replacement method, a certain positive impact will be also brought for production changeovers in the spring industry.
