SK5 rod, Meishan SK5, Yong Wei steel mold (View) provided by the Dongguan City An Yongwei steel mold shop. Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) is a professional "mold steel, DC53, SKD11.SUS440C, SUS420" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to healthy competition in the market, so that "Sweden Assab, Daido, Hitachi, Austria Bluff" brand has a good reputation. We adhere to the "service first, customers first" principle, the permanent mold steel Granville won the trust of customers congregation in special steel, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! The new high-performance cold work die steel SLD-MAGIC performance increase die life and reduce the total cost of production molds and shorten delivery of respect shown considerable advantage. Mainly reflected in the following aspects: - abrasion resistance: The maximum hardness HRC62 its wear resistance increases by about 35%, a substantial increase die life. - Surface treatment of: Surface treatment adhesion film (CVD and other methods) increases by about 30%, high-strength steel to prevent bending, stretching and other scratches generated during forming. - Heat Treatment characteristics: heat-inch variant was reduced by approximately 40%, the deviation shape will be improved. For the size of the heat treatment and surface modification treatment is less, reduce the repair time. - Cutting: the cutting resistance increases by about 35%, based on improving processing efficiency, shorten the processing time in the mold manufacturing. More wear resistance, heat characteristics, surface treatment resistance, machinability characteristic values ??is carried out with the company representative data to compare the material SLD8 possible and actual product resulting property values ??differ slightly. Aging is an important heat treatment operations. The workpiece is heated to below the solubility line, relatively long periods, so that part of the solid solution decomposition, chemotaxis determinate. Sometimes the aging process improves the hardness of materials SK5 material, sometimes you can make the hardness of the material decreases. Using, respectively, depending on the material composition, heating temperature, holding time and other factors. Aging such as cast iron may be at a relatively low temperature, aging the aluminum alloy at about 200 degrees Celsius. China Steel Association data show September 29 direct imports of iron ore 62% grade ore CIF dry powder for $ 78.01 / ton. September average price of $ 82.49 / ton, while the price of imported iron ore was in the beginning of $ 130 / ton import SK5,2011 more years was as high as $ 170 / ton. The reason why iron ore prices fell sharply, mainly due to China's domestic demand is weak, while iron ore production is increased, the supply of new large scale. When the mold to complete production tasks should take different approaches depending on the injection carefully remove residual injection, available copper rod, copper wire and professional mold cleaners remove residual injection mold and other deposits, and then air-dried. Dongguan mold steel disable wire, steel bars and other hard objects to clean, so as not to scratch the surface. If rust spots Dongguan mold steel corrosion caused by injection, to use the grinder polishing and spray on a professional anti-rust oil, then the mold in a dry, cool, no dust at the store. In particular for a tire mold cleaning, mold absorb specific wavelengths of laser energy is very small, will not cause damage to the mold surface contaminants (sulfur compounds, inorganic oxides, silicone oils, carbon black, etc.) to absorb large amounts of energy to be instantaneously inflated, vaporized, away from the mold surface SK5, so as to achieve the cleaning effect. Laser cleaning methods are: 1) Laser dry cleaning method, which uses pulsed laser direct radiation decontamination; 2) Laser + liquid membrane method, which first deposited on the surface layer of the substrate film, and then use laser radiation decontamination; 3 ) Laser + inert gas, i.e., the price of the laser radiation, while SK5, with an inert gas purging the substrate surface. When the dirt from the surface of the release, it will immediately be blown gas from the surface, in order to avoid contamination of the surface again. Learn from the advanced mode of cooperation overall development layout, attract industry leaders building demonstration of industrial projects, the introduction of domestic research institutes, construction research collaboration agencies to support the development of relevant policies, and strive to 5 years or so to build the annual turnover in the "City of Mineral" demonstration base 50 billion yuan scale.
