       The rim is designed as an "O" type crimping structure. This kind of structure allows the rim to be made of a thinner material, it can help to reduce the overall weight of the wheel,And the impact resistance of the wheel is multiplied, it is not easily deformed or torn when subjected to impact, preventing the tire from cracking or air leaking.The "O-shaped steel pipe principle" has better shock absorption effect and is suitable for vehicles with complex terrain and high-intensity work.

       Adopting the self-invented roll forming machine, reduces all 4 steps into 1 step to form a rim with more efficient and high quality, can control the radial run-out and lateral run-out within 0.6mm. And there is no damage, crack, fracture and obvious deformation after fatigue testing. No air leaking after impact testing.

       Adopting the friction stir welding technology, promote the welded part forming forged stage by high-speed high-pressure rotation. Compared with the traditional fusion welding process, this process is more compact and mechanically desirable. The processed product has a strength of more than 50% and a weight loss of 20% compared with the traditional process, which can greatly reduce the energy consumption of the vehicle.

       Have the production and processing capabilities of powder spraying, painting, electrophoresis. The powder spraying line introduces the advanced technology design concept of Germany, and adopts high-end equipment such as suspension chain transmission, automatic temperature control system, movable powder room and cyclone powder recycling system. The steel aluminum wheel pretreatment line adopts the neutral pickling ceramics process, which reduces the corrosion resistance of the aluminum plate and reduces the impact on the environment, and is more environmentally friendly and energy-saving than the original neutral pickling phosphating process.
