Research On The Application Of Lean Production In Carplatform Line

China elevator industry market is very competitive.The elevator manufacturing factory have to face the extensive management,high product manufacturing cost,poor production site management,frequently product quality issues.Continuous improvement,reduce costs,improve efficiency,high product quality is an effective weapon in the peaceful occupation of the market.The company must to use the lean production methods and quality management to achieve competitive excellenceThe improve site is Car Platform product line.Under the lean production theory,we begin to study current production line status,collecting data,draw the current and future value stream map,find the wasting and solve the issues.The main detail actions:By find the existing problems in the current Car Platform product line process,we draw the current and future value stream map.Through implement a series of IE technology and lean production theory such as pull production,one piece flow,quick die change balanced production,and so on to carry on the analysis and improvement.To improve production effective through optimize the layout of Car Platform product line,analysis of customer demand and processing time,to find the process waste,balance the operator's workload,and the use of JIT logistics.Implementing Quality Management,a series of production process optimization and improvement such as product design,product process,and purchase parts.Let the production process is well controlled.Through cooperation with the software company to set up a visualization and information product line.Such as task push,paperless work order,equipment effective,production progress monitoring.The information is necessary and helpful to analyze factory performance and help managers to make better decisions and continual improvement.This article is a lean product improvement base on value stream map.Greatly improve the product efficiency and stable product quality through optimize the production process optimize the layout,quality management,workshop visualization.To confirm the theory of lean production is validity and effectiveness in production.
