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. Mold just include Die, drawing dies, drawing die, pressure die, thread rolling dies, rolling plate, cold heading and cold extrusion die molds. Cold work die steel SKT4 material there, according to its manufacturer with working conditions, should have a high hardness, strength, wear resistance, sufficient toughness, and a high rate of penetration, rate of rigid and other process performance. As a result of improper processing of steel castings, or surface may be formed within the pores, loose, trachoma, segregation, cracks and other defects in the process of thermal processing technology; in forging blank, it is possible to form a shrinkage, segregation, white point, inclusion material, such as cracks. 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. China at this stage is still in the demographic dividend period, there is a lot of labor, lower labor costs relative to developed countries; market, the mold industry, the Ministry of steady advances in traditional markets and actively open up emerging markets, even in the past ignored edge of the market has also been Development SKT4, these are for the mold industry to develop a broad market space; In recent years, the Chinese government has issued a series of policies to support the casting, the development of domestic metal casting industry, but also to create a good development space for the mold industry. 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 SKT4 manufacturers produce ears, it creates a rolling when folded down, the product will crack when folded bend so greatly reduced the strength of steel mold . 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.
