1. Shape repair of BMW 7 series wheel hub. Usually, the damage of automobile aluminum alloy rims is caused by external forces, such as wear, fracture, notch, corrosion, depression, distortion and deformation. Grath's AWR-880 automobile aluminum alloy wheel hub molding machine adopts aluminum alloy professional technology and tools to correct and repair various types of aluminum alloy wheel hub damage without destroying the molecular structure and mechanical properties of aluminum alloy. The present situation that the deformation, distortion and fracture of automobile aluminum alloy wheels can not be repaired is improved. It is the first professional company in China to introduce American aluminum alloy wheel repair technology, which fills the technical gap in this field in China. Second, the wheel hub surface renovation. If only the shape of the hub can be repaired, but not the surface of the hub, then the hub repair will lose its meaning. The surface of automobile aluminum alloy wheel hub can be divided into four categories, namely, painted surface, polished surface, numerical control surface and electroplated surface. Grath not only pays attention to the introduction of repair equipment for automobile aluminum alloy wheels, but also actively introduces technologies and materials for surface renovation of aluminum alloy wheels. In addition to the common spray-painted wheel hub surface, it also imported the commonly used high bright silver electroplating paint from the United States, which greatly met the requirements of different customers for personalized wheel hub surface renovation. At the same time, grath can also provide technologies, processes and materials for surface polishing and silver electroplating of aluminum alloy wheels. And can guide customers to deal with CNC surface problems. Both the appearance and hardness of the refurbished wheel hub surface can meet the OEM quality requirements, which makes the scratches and abrasions caused by special wheel hub surface treatment processes in the past, such as CNC treatment and electroplating, become history, and makes China's aluminum alloy wheel hub surface renovation technology synchronized with the world. First, the wheel hub shape repair (solve the wheel hub wear, fracture, notch, corrosion, depression, distortion, deformation and other problems. )-The edge of aluminum alloy hub is scratched and damaged, which is the most common damage of aluminum alloy hub. When the automobile aluminum alloy hub rotates against the curb, it is easy to damage the outer edge of the hub. In this case, grath can repair it perfectly through professional aluminum welding technology. Edge damage of aluminum alloy wheel hub When an automobile aluminum alloy wheel hub is accidentally hit by a hard object, it is easy to cause the edge of the automobile aluminum alloy wheel hub to break. Usually in this case, the car tires must be replaced, but grath can be perfectly repaired by welding, shaping and air tightness testing. Edge notch of aluminum alloy wheel hub When the hard aluminum alloy wheel hub is violently hit by stones or other hard objects, the edge of aluminum alloy wheel hub of automobile will usually be hit into a notch. According to the shape of the crack, Grath can be perfectly repaired by surfacing, air tightness test and surface treatment. Fracture of aluminum alloy wheel hub The left picture shows the fracture of aluminum alloy wheel hub of automobile. Don't ignore small cracks, which have serious security risks. Don't let it endanger your driving safety. We can repair this wheel hub perfectly through crack welding, air tightness test, polishing, baking paint and other procedures. Distortion of aluminum alloy wheel hub. When the car is hit by a strong collision or a hard object, it is easy to cause the flange of the aluminum alloy hub to bend and deform. As long as the structure of aluminum alloy wheel hub is not damaged, our aluminum alloy wheel hub repair experts can correct this damaged wheel hub through professional repair equipment and special technology. Second, the wheel hub surface renovation (to solve the wheel hub surface damage such as painting surface, polishing surface, or CNC surface, electroplating surface, etc.) Painting the wheel hub surface renovation is the most common wheel hub surface effect, and grath Company is absolutely confident to repair all kinds of scratches, scratches, bumps and other injuries on the painted wheel hub surface. At the same time, grath also provides personalized wheel hub surface renovation services according to the needs of different customers, so that your car can experience a colorful Christmas. CNC wheel hub surface renovation CNC wheel hub surface is very dynamic, giving people a very MAN feeling, deeply loved by men, with high added value and rapidly rising demand. However, the renovation of this kind of wheel hub has strict technical requirements. Grath company is equipped with professional repair equipment, and does professional things with professional heart, which can perfectly repair all kinds of CNC curved grinding wheels. For example: Camry, Accord, polished wheel hub surface renovation. The polished wheel hub surface has natural metallic texture, bright luster, bright appearance and strong visual aesthetic feeling. However, refurbishing and polishing the wheel hub requires special skills and professional polishing equipment and materials. Grath can easily and perfectly renovate this wheel hub.
