Suining DAC, DAC manufacturers, Yong Wei steel mold (certified merchants) 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! Determines the shape of the mold shape of these products, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after the restructuring, will be increasingly high precision molds, mold steel requirements are also increasing. High-speed steel quality even without segregation, wear resistance, high toughness, to meet the requirements of the service life of the mold manufacturing. Different furnace DAC suppliers, power is not the same. Not the same as the heating medium heating capacity is not the same, of course, will be different heating rate, in general, the heating due to thermal conduction effect, much faster than the box-type furnace in a salt bath furnace and lead bath heated faster than salt bath Furnace is also fast. DAC on mold steel sheet market wholesale prices overall fell. Hot rolled coil prices relatively small decline DAC, Shanghai, Hefei, t price fell 20-50 yuan week. Shanghai market is hot-rolled prices rose and then fell, the market traded poor business mentality turned pessimistic, increasing the prices of space. Plate dropping the overall market is vulnerable, Shanghai, Jinan and other places t price one week fell 20-80 yuan. Shanghai market, demand gradually weaker, and in turn replenish the resources of new goods into the market, the supply pressure is diminished. Businesses can only wait and see. In the mold production costs, material costs typically account for 10% to 20%, while the machining, heat treatment, assembly and administrative expenses accounted for more than 80%, so the process performance of the mold is affecting the production cost of the mold and manufacture the main factors of difficulty One. Steel mold processability, thermal processing performance DAC price refers to thermoplastic processing temperature range; cold performance, refers to the cutting, grinding, polishing, drawing and other processing performance. Cold work die steel are mostly eutectoid steel and ledeburite, hot and cold performance is not very good, it is necessary to strictly control the process parameters of hot and cold worked to avoid defects and waste. On the other hand, by increasing the purity of steel, to reduce the content of harmful impurities, improve organizational status of the steel, hot and cold worked to improve the properties of the steel, thereby reducing the production cost of the mold. Tempers mainly used for ultra-high-strength steel, spring steel, forging mold and other uses tempering tempered troostite tissue. This treatment process so that the steel material is the best elastic limit, a sufficient hardness and a relatively high strength level. Able to completely eliminate the quenching stress, forming part of the granular carbide. The heating temperature is usually 350-500 ° C heat. From the perspective of the current combination, the recent rapid rise in futures prices was mainly due to the replenishment of steel on the spot after a certain boost to the National Day, iron ore futures took the opportunity to repair the structure caused by the depth of the premium, and with continuation rhythm of the market, after a high premium is expected to be further narrowed. However, the structure of the iron ore futures premium actually reflects market expectations of future price of iron ore, futures premium to the spot market is relatively bearish on behalf of future ore prices, this structure since before iron ore futures on has been formed, and with the continued increase in international iron ore supply, as well as the decline in China's steel output growth, the future of the international iron ore market oversupply situation has been basically formed, futures prices continued premium to the spot also in line with common sense.
