Analysis of China mold industry development
Over the past 30 years of reform and opening up, China's mold production as an industry has undergone enormous changes. The change is mainly embodied in three aspects: productivity change, mode of production change, and technological revolution. Most people see the Chinese mold industry as an industry from scratch, from small to large, from the missing to fill the main force, as well as the rapid growth of mold demand and output changes. But more importantly, the mode of production changes and technological revolution. The latter two changes are a more profound and fundamental change. Change the mode of production is mainly reflected in the past, from the traditional small and complete rear workshop, workshop style production, transformation of large-scale production is highly professional market cooperation; from non-standard production to the relative standard and standardization of production. Mold production technology revolution, concentrated to one point is enterprise information, that is, digital manufacturing and information management.
Before 1980s, many moulds were polished by hand by the fitter. In 90s, due to the introduction of CNC machining tools, EDM and other more advanced equipment, greatly improved the production process of the mold, the production cycle and mold quality has been greatly shortened and improved. High precision machining has freed workers from heavy manual labor. On the other hand, cad/cam/cae technology in the mold industry has been widely used, the level of mold design and NC machining has been greatly improved, work efficiency and reliability of cad/cam/cae software for mold design and technical personnel has been greatly improved. At present, the mold enterprises are facing a new topic, how to liberate the enterprise management from the trivial affairs, and make the information management to contribute to the improvement of the enterprise's production efficiency. Therefore, the mold enterprise management information has become the mold industry development and progress of the inevitable trend.
Mold production is a single order type production, in the management of information has its strong particularity. Design is part of the manufacture, process design is inadequate, and design and process information can be directly reused, of little value. Therefore, according to the characteristics of enterprise production, it is the key to grasp the balance between comprehensive information management and practical and simplified management. This makes it difficult to copy mature management software. For example, the car mold enterprises do not have the traditional sense of raw materials, warehouse management and so on. Purchased are all parts and components of semi-finished products, there is no storage, delivery process, manufacturing costs of amortization, each enterprise is also different. For example, cost accounting should adopt the method of project management instead of adopting general processing and manufacturing methods. What software such as PDM, ERP and so on can not be adapted completely without thorough transformation.
With regard to the level of China's mold industry, the goal of the development plan of mold industry is to enter the advanced level of Asia in 2010. As far as quantity is concerned, we are now the world's largest producer of mold. From the product level, B level and below grade cars and other passenger cars and commercial vehicles such as a full set of supporting auto mould, for the electronics industry supporting precision up to 2um, life of high speed precision multi position progressive die for more than 200 million times, a single set of mold weight more than 100 tons of large die, large station level up to 6 meters into the mold, the light guide plate mold, mold, mold and other optical biochip has many high level mold can produce. However China vast, many of the world's mold enterprise level is uneven, the gap between them is very large, from the overall level, compared with the international advanced level, but also there are many gaps prompted us to further efforts, prompted us to forge ahead gap! To the world mold power continues to move forward, will still be our goal in a long time.
