Detailed Product Description: | Yong Wei mold steel | 4CR13 Suppliers | Yunfu 4CR13 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 gating system, namely the nozzle from the injection molding machine to feed the cavity between 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 4CR13 material, therefore, may be boron or boron nitriding carbonitriding 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, infiltration and titanium craft 4CR13, can be used to deal with cold and hot die, including TD method (molten metal infiltration) has been some applications, can improve die life a dozen times and even times. The carbon content of the steel and alloying elements are often, it's thermal conductivity is poor. If heated too quickly, is bound to cause a lot of thermal stress 4CR13 sheet, so that not only can cause heating of the workpiece becomes open, but the quality of heat treatment is unfavorable. Therefore, high carbon steel, high alloy steel, high speed steel type of steel must be heated slowly (or define certain heating rate), sometimes even before heating to the desired temperature once or twice to warm up. Such as high speed steel hardening, preheating it twice. According to the latest market report on the well-known steel information organizations "My iron and steel" offer, last week, the domestic spot steel price index pulled back slightly to close at 111.11 points 4CR13 die steel, fell 0.08 percent the week. Market participants observed last week and billet steel futures price linkage to rise, driven by a significant increase in confidence in the spot steel market. But by this week, futures and billet prices both correction, spot steel prices also will adjust the downstream is slowed down the speed of purchase. |
