Yong Wei mold steel, S500 mold price, Yunfu S500 provided by Yong Wei 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 the working conditions of its manufacture with S500 mold price, 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. 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. Gating system, ie from the injection molding machine nozzle to the cavity between the feed channels, including sprue, runner, gate and cold slug. Especially selected gate location should be conducive to the cavity filled with molten plastic flows in good condition, the solid runner and gate attached to articles on cold material at the top of the mold is easy to be removed from the mold and (heat except channel mode). Generally speaking, the financial crisis on the sheet metal industry does have some impact. But the sheet metal industry under the wave of the financial crisis shows a good development trend. Production and sales in domestic and international markets throughout the sheet metal industry in the financial crisis basically complementary balance can be achieved, so the financial crisis on the sheet metal industry has little overall impact on the amount of orders. Boronizing process commonly used in a variety of cold mold, due to the improvement of wear resistance, mold life can be increased several times or ten times. Sometimes the use of medium carbon steel Boronizing can replace high-alloy steel mold. Boronizing hot die can also be used, such as hot extrusion molds. Boronizing brittle layer, the diffusion layer is thin, weak support for the nitrided layer, therefore, can be used boron nitriding or carbonitriding boron to strengthen the transition zone, the hardness changes gently. To improve the brittleness of boride layer, can be boron vanadium, boron and aluminum alloying. Alloying including Chromizing, vanadizing, seepage titanium and other technology, can be used to deal with cold and hot die, including TD method (molten metal infiltration) has been some applications, can improve die life several times and even ten times .
