When the engineering machinery is being in the outdoor work, It is prone to happen the fortuitous events to pull, scuff or rub against the sealing members, such as the hydraulic cylinder and hydraulic rod, and these damage will cause the bad effect of petrol dripping and gas blowing by. So the equipment cannot operate normally. Most of the engineering machine's hydraulic fittings are precision parts, some of the engineering machine's hydraulic fittings are the imported components, these components are very expensive to buy and are not easy to install. Simultaneously, time limit for the engineering project is almost very serious, so the time limit for the engineering project will be affected with spending a lot of time and energy to by these fittings. Aoyuksin repair technology can finish the repair work locally, and most of the components can be repaired without disorganization with the repair material being the nickel-chromium two-component alloy whose performance of abrasion resistance has surpassed the original part, during the repair process, temperature of the parts won't rise and the thermal deformation won't occur, so the original precision of the part won't be influenced.
