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 mold the steel mold steel, 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 hardness 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; in the blank forging die steel supplier, are likely to form shrinkage, segregation, white spots, 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. China's mold manufacturing plant is produced from the most points with the tool and die shop (factory), professional mold factory are mostly "large", "small" form of organization. Foreign mold companies are mostly "small and specialized," "small but excellent"; die with self-production ratio of up to 50%, more than 70 percent of foreign commodities mold. Zhuhai mold steel mold nurture talent in itself is a long process and requires the accumulation of years of experience. And limited to software and hardware facilities, some universities Zhuhai mold steel train professional students practical skills is not enough; the same time, the lack of standardization of vocational teaching standards has led to all kinds of training courses in the community are also mixed. Mold steel hardness testing will focus on three cases in which mold steel material hardness testing, heat-treated semi-finished mold detection requires the detection surface hardness and high wear resistance, hardness mold surface after the heat treatment. Supply Status tool steel is mainly through forged steel, steel blocks or bars, generally supplied in the annealed condition. Some plastic mold steel also to the pre-hardened state (quenching) supply, the user can be directly processed into the mold without subsequent heat treatment. In the context of the economic slowdown, the automobile consumption has been no small impact, since the second half of this year, car sales growth slowing, China Automobile Industry Association data show that in September auto sales year on year growth fell further to 2.5 percent, the lowest level of the year, total sales in the first nine months fell to 7.05 percent year on year growth.
