                Siji Moulds and Tooling Company

                      It is originally a subsidiary under CSR Sifang Locomotive and Rolling Stock Company, and reconstructed with Qingdao Victall Railway (Group) Company on the year of 2003.It is a manufacturing enterprise which integrates the research and development, design, manufacturing and after-sales service. The main products include hatch mechanism, various types of water tanks, aluminum parts and stainless steel welding parts. The floor area of company is approximate 20,000 square meters with 400 employees at present, among whom 70 technician. To ensure the quality of products, we set up special internal welding institute, and hire professional expert to provide training for operators; furthermore we organize related technicians to carry out qualification evaluation. We passed SLV EN 15085 welding system certification, AWS welding certification and ISO9000 quality management system certification.


                      We stick on improvement of “island” and “line” construction on site, there are 36 working islands and 3 production lines at present. We adopt Cell mode of lean production for management of island to maximize the efficiency of working hour, which is a speedy way to improve production efficiency. Through the optimization of layout of island, we improved the movement efficiency for fetching material and tools, minimized the waste of movement, streamlined the assembly process, and improved the working efficiency. We apply fixed material, fixed position and fixed quantity for material management on site, make the inventory more clear which pushes the demand of material and reduces the quantity of materials and semi-products on site, all measures result in improvement of JIT and working efficiency and keep layout orderly. The instruction documents facilitate the reviewing when needed by operators, which is put close to working area and visible for operators. The real time monitor of water tanks is secured through production process Kanban. The assembly island of hatch mechanism is completed through the improvement of people(fixed operators), machine(equipments and tools), materials (The Three Fixed), method(instruction document) and step(on site layout), which result in great improvement of working efficiency.font>
