Domestic steel reaction injection moulding urgent need to increase research and development efforts

In recent years, with the rapid development of reaction injection moulding industry, as domestic steel mold provides a huge market, driven by domestic production mold steel, varieties, specifications and quality standards improved. China's metallurgical industry, research MASTER reaction injection moulding and development and the introduction of a large number of steel required for the mold industry, but domestic steel mold in terms of the variety and quality is still difficult to meet all the needs of the domestic market of the mold. In cold work die steel, for example, China's only cr12, cr12mov, crwmn steel. Our cr12mov steel, molybdenum and vanadium content is lower, worse than d2 steel overall performance. crwmn higher carbon content, and does not contain vanadium carbide network prone to severe, affect performance. pvc pipe fitting mould Today abroad to high-precision, standardized according to the development trend of cold stamping, had developed a high-performance tool steel, which has a secondary hardening steel ocm, dc53, vasco, die; flame hardened steel sx10570l; air quenching steel a4 and other micro-deformation. The country is also in urgent need of new die steel developed. Domestic hot work die steel gap also exists at present China's general steel only two kinds of steel. The foreign addition to the common types of steel, but also the development of a new yhd3, h26 and other varieties. Plastic mold steel gap Plastic injection mold makers is even greater. On the species, the current national standard is only a steel, while the United States has seven steel and steel to form a more complete series. In addition, business-to-die steel mold manufacturers also made a number of specific requirements: 1. Domestic new modern mold factory mold steel (module) usually require heat treatment and machining. Such as hot work die steel heat treatment and require a six-sided machining; rounded precision flat die steel requirement is less than 0.5mm; plastic mold usually requires quenched state after finishing supplier, and so on. But these require some mills currently difficult to satisfy all. 2. Delivery time for tool steel and higher requirements. Fast-paced, modern production, requiring mold manufacturing cycle is very short, usually in about 30 days. Design and preparation of which not more than 10 days, and requires the same time. This requires only a mold steel delivery deadline under 5 heaven, and reaction injection moulding manufacturer of tool steel is basically the implementation of "zero inventory" management model, a model someday, someday purchase materials. This requires plastic container molding that the steel must meet end-user demand for modern production for the embryo. 3. Requests for reaction injection moulding steel mills quality and life assurance and commitment. Because of modern, large-scale, complex, long-life mold is extremely expensive, so manufacturers mold steel quality and extremely concerned about their life, preferring to spend more money, but also to ensure the quality of steel. If the country can not meet, they prefer to import from abroad. According to conservative estimates, in 2005 the domestic consumption of at least 500,000 tons of steel mold, where the market is huge, but the domestic steel mold manufacturing enterprises in order to occupy a greater share therein, we must open up the research and development, technological innovation, market devote greater effort.
