Yong Wei mold steel | S-STAR wholesalers | Zhanjiang S-STAR 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, 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 . Shoddy material surface is easy to crack because it is blank adobe, adobe many pores, adobe in the process due to the cooling effect of S-STAR price of the thermal stress, cracks, after the rolling had cracks. No shoddy steel metallic luster, pale red color of iron or similar imported from Japan, S-STAR, the reason there are two two, it's blank is adobe. 2, shoddy-rolling temperature is not standard, they are visually steel temperature, so that can not be prescribed by rolling austenite region, the natural properties of steel can not be reached. Important uses for steel and alloys, sometimes using more than twice tempered. For tool steel, tool steel, steel casting molds, stamping die steel, hot die steel, cold work die steel, tool steel and high carbon cars than the steel can be processed using this technology. To a certain extent to suitably increase the hardness level, improve the dimensional stability, and further to eliminate the residual austenite to eliminate thermal stress and stresses caused by the previous tempering. For high-speed steel is often carried out three times or more tempered. Iron ore prices are so depressed S-STAR, the supply of iron ore to China had a profound impact. Direct impact on the domestic mining began large-scale production. With the high cost mines are gradually out of the market, the end of September the mine capacity utilization rate of iron ore fines 61.8% S-STAR suppliers, compared with the beginning dropped 17 percentage points higher mining costs of iron ore, most of the mines depth of about 300 meters, the survey shows, the cost of production of iron ore, Shanxi, Liaoning Province (not included) Mainstream between $ 90-110. In addition, iron ore companies also bear certain taxes, in 2014 a quarter of China Steel Association announced corporate tax burden of iron ore mine average rate of 21%, up to 30%, taxes have more than 20 projects.
