Chongqing Kesaibang Technology Co., Ltd

Chongqing kesaibang Technology Co., Ltd. Owns patents of "a method for producing wheel hub by forward and backward extrusion" (invention patent), "equipment for producing wheel hub by forward and backward extrusion, " integral forging wheel hub combined mold "and other magnesium alloy billets. On July 26, 2018, the technology passed the expert review of the Ministry of industry and information technology. The experts unanimously agreed that the patent technology of forward and backward extrusion forming of forged magnesium alloy automobile wheel hub is advanced and innovative, reaching the international advanced level, which is an important technological breakthrough to realize automobile lightweight and in line with the national industrial policy. The technology has become increasingly perfect and has the potential of industrialization and large-scale production The technology is of practical significance to the automobile lightweight and the high-end application of magnesium in China, which has laid a good foundation for the promotion and application of forged magnesium alloy wheels in automobiles. Both Ma zuopo and Shang Shouliang, the original promoters of the company, have been engaged in deep processing of magnesium alloys for more than 20 years. They have rich experience in magnesium and magnesium alloy raw materials, magnesium die casting, magnesium extrusion, magnesium forging and other technologies. The team has established magnesium alloy die casting plant, 2 extrusion plants, 2 magnesium rod production plants and 2 magnesium alloy wheel hub production plants for 4 years. 2, Process introduction -One time forward and backward extrusion forging process has the advantages of short process, high efficiency and stable quality. 3, Authorized manufacturer-The products of Dewei Technology Co., Ltd., which are generally authorized by this process, have been sold in batches to Germany, the United States and Japan; The 20 inch forged magnesium alloy wheel hub of a high-end off-road vehicle of Ford in the United States is in the mold development stage, the new GTI model of Volkswagen in Germany has been installed and used, and the 20 inch magnesium alloy wheel hub of Porsche in Germany has begun to send samples, with an annual demand of 12000. The domestic FAW Hongqi 19 inch magnesium alloy wheel hub has passed various bench tests and road tests, and is expected to be installed and used in batches in May 2020. Haike magnesium industry (Macheng) Co., Ltd. Is generally authorized to produce 1 million magnesium alloy wheels per year, which is expected to be put into production in October 2020. To build a magnesium alloy wheel base, it has obvious advantages in industry and location. 4, Advantages of forged magnesium alloy wheel hub1. Safety: Magnesium alloy automobile wheel hub has high strength, good impact resistance and strong fatigue resistance; It has light weight, reduces inertia energy, reduces driving torque, improves speed, brakes quickly and reduces braking distance; It has low high temperature dependence and good heat dissipation performance, reduces wheel burst and extends tire service life. 2. Comfort: Magnesium alloy material has good damping, strong shock absorption, shock absorption and noise reduction, which improves the comfort of the car. 3. Operability: The mass of magnesium alloy wheel hub is 40% less than that of aluminum alloy wheel hub, which means that the suspension system has better dynamic response ability, so the operability is better. 4. Energy saving: The wheel hub of magnesium alloy automobile is light in weight, which reduces the load of the whole vehicle (the wheel belongs to unsprung mass, and its weight reduction effect is 10 times of that on the body), so as to reduce energy consumption, save fuel, and save oil (electricity) by 8% - 18%.
