Casting mold refers to the model in order to get qualified parts, ordinary manual, commonly used wood model, plastic model, mechanical model is multi-purpose metal model. In recent years, casting mould industry is developing rapidly in China, growing at an average of 17%, higher than the average value of China's GDP more than doubled. The development of casting mould can be synchronized, so that the casting mold also has the very big development space.
China casting mold industrial development to today, has experienced an arduous journey. Casting mould industry in China after years of development, has made great progress, but its development still exist many problems. According to understand, these problems mainly include: independent innovation ability is weak, backward equipment and technology, the lack of with the core competitiveness of the enterprise group and international well-known brand, casting mould enterprises small in scale, low industrial concentration, product structure is unreasonable, in the global industrial chain division of labor and low-end state in the short term is difficult to change, high input, high consumption, high pollution and low efficiency, low benefit of extensive development mode, industry foundation remains fragile.
Although China is casting superpower, but far from casting power, casting process in our country, casting quality, technical and economic index such as there is a great gap compared with advanced countries. The casting mould industry in China there are still a lot of substantive issues. Such as the casting mould enterprises small in scale, low industrial concentration, product structure is unreasonable, the independent innovation ability is weak, backward equipment and technology, the lack of with the core competitiveness of the enterprise group and international famous brands, in the global industrial chain division of labor and low-end state in the short term is difficult to change, high input, high consumption, high pollution and low efficiency, low benefit of extensive development mode, industry foundation remains fragile.
Compared with the Japanese quite mature and stable casting mold industry development, walk in the forefront of the world in the same industry.
Why Japan casting mould industry have today's achievement, because the Japanese upfront design casting mold enterprise really doing very fine, all 2 d drawings of very fine, and all labeling of tolerance. Japanese companies pay attention to the research of processing technology, the casting mould of rough machining, finish machining, electrical pulse, thread cutting process is formulated the detailed technical specification, including positioning, machining allowance, in the process of machining parameters are included in the specification, in the process of production, are processed by process specification and technology standard, shall not be deviation. Japanese companies in the quality control of casting mould requirements in strict accordance with the drawings, the introspection on the processing after the completion of all employees and make records, including cavity after finishing, use advanced 3 d scanning and 3 d detection equipment, directly determine whether within the tolerance, the principle is qualified rear to turn to the next working procedure.
