Technological backwardness easily found, poorly managed easily overlooked. Domestic enterprises have adopted over the last part of the mold workshop-style management model, truly modern enterprise management, not more. Currently mold manufacturer uneven conditions seriously affected the accuracy and quality of the mold. Zhuhai such as precision mold steel heat treatment areas, different mold materials, mold making homemade quality in appearance and service life difficult match with foreign products. Zhuhai steel mold-made molds are many and abroad using special mold materials used, their mechanical properties, wear resistance, corrosion resistance and superior brightness polishing. Chinese standard GB / T1299-2000 "alloy tool steel" provides annealed condition of the steel, for different grades of hardness value should be less than a certain value, or within a range of hardness, such as: hardness hardness 197-241HBW 217-269HBWCr5Mo1V hardness ≤255HBW. Depending on the sample quenched hardness grades, generally between 53-64HRC. Construction steel market prices in order to stabilize the main southern construction steel prices steady rise; plate market prices basically stable; hot rolled coil prices to stabilize the main; cold-rolled coil prices steady fall; Tudu coil market prices basically stable. National Development and Reform Commission deputy director of the National Energy Bureau Wu-hsiung said the 9th, to promote the development of coal-fired energy saving and emission reduction upgrading and transformation, Energy Bureau scientific power development plan, reasonably determine the annual thermal power construction scale and guide local optimization of thermal power project layout on the low utilization hours of thermal power (4500 hours or less) area SUS420 wholesalers, to strictly control its thermal power construction scale year. To be able to quickly and efficiently remove the margin, and there is a high reliability, in order to maintain long-term continuous full-load operation, the table size should fit the mold dimensions SUS420 suppliers, suitable rectangular or square and round, not narrow length, height and direction of travel but requires a larger space. Machinery casting machine after being eliminated or end of life, can be remanufactured by creating new value, creating a post-market services, and the formation of larger profit margins. Die Casting Industry fairly quickly. Dongguan mold steel This is mainly because: first, the number of foreign companies generally do not die casting more than one hundred people, most of the mold foundry number fifty people look at their personnel structure arrangement is also very reasonable. Recent studies show that mold steel by cryogenic treatment (-196 ℃), can improve its mechanical properties, some die after cryogenic treatment significantly increased service life. Cryogenic steel mold can be between quenching and tempering processes carried out, but also for cryogenic treatment after quenching and tempering. If you still retain residual austenite in quenched and tempered steels, then after cryogenic treatment remains tempered once again. For strict security product quality bearing steel hot-rolled coil Division was established research team conducted in-depth exchanges with customers on product performance and communication SUS420, sizes, etc., organize technical and production departments to formulate advance, audit, issued production technology procedures, and job training for system employees. For production, process control and difficult to develop a detailed trial plan, in the production process SUS420 hardness levels of the Ministry of Technology engineers focused their attention on the field guide, structural steel by adjusting the ratio of carbon, silicon, manganese, phosphorus, sulfur and other elements optimize the vanadium, boron hit zone, the implementation of a protective cast, to ensure the slab quality to meet the requirements.
