Since the eighties, plastic rattan molding has entered a period of rapid development, which greatly promoted the production and application of technological advances in tool steel,
MASTER plastic rattan molding through the introduction of advanced equipment and technology, is capable of producing a variety of high-quality tool steel, domestic steel mold and quality has made great progress and improve. However, the aggregate level, the country is still relatively backward steel mold, especially for the manufacture of high-grade steel mold, still in use imported steel, compared with the international advanced level, mainly in the following gaps:
1) die steel varieties, specifications incomplete, more low-level, less high-grade. High-quality, high-performance tool steel varieties less. In terms of species, not yet formed plastic, glass, building materials, ceramics and other special mold steel series. Flat steels, modules, relatively low proportion of fine material products, utilization of steel about 10% lower than in other countries. To meet the manufacture of large, sophisticated, complex, requiring high life of the mold,
thin wall injection molding the overseas development of pre-hardened steel, while the domestic steel basically stay in the annealing stage, or hot-rolled state delivery, and long lead times, which is China's home appliance industry the main reason a lot of die steel imports.
2) a lower degree of specialized production mold steel. Quality steel, poor performance stability, poor visual quality. Chinese scattered in dozens of die steel production, most of the manufacturers of production technology and equipment is not complete, especially in the rear of the process, processing equipment behind, thereby constraining domestic steel mold improve improve quality and performance.
3) die steel supply and marketing channels remain open. plastic rattan molding manufacturing, mostly single or small batch production, and varieties of steel required, specifications, a small number, the demand for timely delivery of industry characteristics, and mass production of metallurgical plant contradictory.
garden plastic chairs mold May at any time resolve the problem of foreign retail stores through steel. China in recent years there have been some agents, steel shop and other intermediate sales cycle, but in the mold steel sales of service and level of foreign advanced level there is a gap, affecting the promotion and application of domestic steel mold. For example Bohler - Uddehum 100,000 users worldwide, mostly engineers, guiding users.
It is noteworthy that matter, China's mold quality and service, from the gap between the needs of users is quite large, so we had a lot of "prefer a higher price abroad, do not want to buy a home at a low price" is not a normal phenomenon. Domestic and international prices of some steel mold is shown in table 1. From the table, than the domestic price of imported steel prices 3-6 times higher, reflecting the backwardness of China's mold steel from the price gap between the same grades
