SKD11 Hardness | AsiaVest mold steel | Shaoguan provided by the Dongguan City An Yongwei SKD11 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! Special quality steel is especially needed in the production process strictly control the quality and performance of steel, indicators of its quality control provisions in its standard belongs, in representation of the representatives of steel symbol indicates that as A, E, C, etc., foreign steel quality level is not marked, but marked refining methods used or made some improvement, improvement, as expressed by the ESR ESR; VAR G50; VIM vacuum induction furnace; mod expressed as some improvement or the like. The greater the temperature difference between the inside and outside of the workpiece, and thus is easy to cause thermal stress in the heating process causes deformation. So heated pace of cross-sectional size of the work should also be considered: a large cross-section should be slower; on the contrary, a small section of the workpiece, the heating rate can be faster. In the construction steel market, although prices overall still continues to rise, but the increase has been a marked contraction. Shanghai, Jinan and other places t price week rose from 20 to 180 yuan, Tianjin, Shijiazhuang and other places have fell, t price decreases in the 20-70 yuan. Currently, the business confidence have turned cautious, market transactions are gradually shrinking. 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 SKD11 prices and sprayed with anti-rust oil SKD11 professional manufacturer, then the mold in a dry, cool, no dust at the store. Laser in particular for a tire mold cleaning, mold absorb specific wavelengths of energy minimum hardness of SKD11, 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 expanded vaporized, away from the mold surface, 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 SKD11, namely first deposited on the surface layer of the substrate film, and then use laser radiation decontamination; 3) Laser + inert gas, i.e., while the laser radiation, 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.
