Yong Wei mold steel | Sales die steel | Shantou mold steel supplied by AsiaVest steel mold. We are Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) located: Dongguan, Guangdong specializes in: mold steel, DC53, SKD11.SUS440C, SUS420 die just include Die, drawing die, drawing die, pressure die , thread rolling dies, rolling plate, cold heading and cold extrusion die molds. There are steel cold mold, according to its manufacturer with working conditions, should have a high hardness, strength, wear resistance, adequate toughness, and a high rate of penetration, rate of rigid and other process performance. Mold just include Die, drawing dies, drawing die, pressure die, thread rolling dies, rolling plate, cold heading and cold extrusion die molds. There are steel cold mold, according to its manufacturer with working conditions, should have a high hardness, strength, wear resistance, adequate toughness, and a high rate of penetration, rate of rigid and other process performance. Thermal processing such as steel castings in the process due to improper processing technology, or surface may be formed within the pores, loose, trachoma, segregation, cracks and other defects; skd11 in the blank forging die steel, are likely to form shrinkage, segregation, white points, inclusions, cracks, etc. These defects have a great influence on the quenching cracks steel. In general, the more severe the original defect, the greater the tendency of its quenching cracks. Some plastic materials have acid resistance, and some by the addition of a reinforcing agent, or other modifications, such as glass fibers sold large die steel mold damage are to be considered during the selection. There is a strong corrosive plastic general election S136,2316,420 a class steel, in addition to the election S136,2316,420 weak corrosive, there SKD61, NAK80, PAK90,718M. Strongly acidic plastic material has: PVC, POM, PBT plastic material has a weak acid: PC, PP, PMMA, PA, single-medium quenching quenching method is the most common, simple operation, equipment, and environmental requirements low. Inadequate water quenching is easily deformed steel, alloy steel water quenching easy to crack. The method of operation is the end of the holding time of a workpiece into the quenching medium to the cooling capacity of the quenching cooling medium, the cooling conditions in this process depends entirely on the cooling characteristics of the workpiece using the medium. Mills use superior resources, weaknesses, the stainless steel products do fine well, despite the current market lower, but many businesses is not overly worried, because excellent product quality, while the current market even approaching low, as long as the resistance maintained, seize the opportunity to make the anti-hunters also a high probability event. National Day, the iron ore spot market transactions are extremely active, continuous heavy volume of cargo turnover also die steel wholesaler, Dalian iron ore futures even once the daily limit to close at Platts, the highest index also rose $ 83.75 / ton, the highest for nearly a month highs, market sentiment continued to pick up. However, iron ore prices really have bottomed out? In fact, this is also related to the late steel to determine the trend, following the author of the latest changes in the market, as we do a brief analysis. Look forward to all of us to grasp the current market situation changes help.
