Welcome to inquire! Contact: Simon / R. Some plastic materials have acid resistance, and some by the addition of a reinforcing agent, or other modifications, such as glass fibers the major damage to the mold, are to be considered during the selection. There is a strong corrosive plastic general election S136,2316,420 a class steel, weak corrosive election S136,2316 SKT4,420 addition, 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 SKT4 plate, the cooling capacity of the cooling in the quenching 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 SKT4 material, as long as can endure SKT4 material, anti-hunters to seize the opportunity to earn a high probability event also. National Day, the iron ore spot market transactions are extremely active in cargo turnover is also continuous heavy volume, Dalian iron ore futures even once the daily limit to close at Platts, the highest index also rose $ 83.75 / ton, the highest in nearly a month highs market sentiment continued to pick up.

Shoddy die steel prone to folding. Folding is formed on the surface of a variety of die steel fold, this defect often throughout the product's portrait. The reason is due to shoddy manufacturers of folding the pursuit of high efficiency, reduction is too large, resulting in the ears, it creates a rolling when folded down, the product will crack when folded bend, making the strength of the mold steel declined significantly. October is the best month of the domestic infrastructure construction, but also the only good outdoor construction during the year "days"; in infrastructure in order to complete the annual task of pressure, I think, this time next month or so, is the outdoor infrastructure Project construction season, at rush period, driven by demand for steel and other construction Xianluo should also release a more centralized point. The September manufacturing PMI index is relatively stable, indicating that the domestic economy is stable, but lower portion of the index also reflects the economic side there is still downward pressure in the future. At the same time, good bad macro intertwined; relax or stimulate the property market, real estate credit market confidence, but it is difficult to form a clear effect in the short term.
