Yong Wei mold steel | RD25 tungsten steel | Wuzhou RD25 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 high demand due to the mold surface quality and distortion, high-pressure gas quenching vacuum has almost become an irreplaceable mold heat treatment technology. Currently in the south and east coast, slightly scale private heat treatment processing enterprises have at least one 0.4MPa (most have six) high pressure gas quenching vacuum heating furnace. Widely used in the cutting tool industry RD25, CNC and machining centers, strong demand tools with high quality and long life, while the city's environmental protection also proposed more stringent requirements for heat treatment, vacuum heat high pressure gas quenching has thus become the high-speed steel cutting tools Heat Treatment Hardening of the first alternative to salt bath process. FDAC mold steel with a rapid tooling, excellent high temperature strength and wear resistance, hardness at the factory has reached HRC40-44, so no heat can be used directly in production, can greatly reduce the processing time to die. 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 RD25 rod, 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. Boride layer brittle RD25 suppliers, the diffusion layer is relatively thin RD25 steel nitrided layer support for weak, 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 .
