Gaomi Tianyuan Precision Manufacture Co., Ltd. was established in 2000, and is located in Gaomi economic developing zone in the west of Qingdao city 60 kilometers. Produce the precision mechanic products mainly . We have lots of advanced computer-controlled processing equipments. Produce precise component and parts used in each industry field. Automobile exhaust gas turbocharger is one of our excellent products.We Specially preduce super turbocharger used in car. Especially for example type: 2.0T ã€1.8Tã€1.6T ( OEM number:054 145 703J or 5303 988 0025 and 5303 988 0052, K03/04 Series) and so on. We have comparatively enough experience about minitype with medium-sized turbocharger, its rotator axis is very thin. heat treatment demand is very high.keeping linearity is very difficulty.But all of this is very easy for us.Material adopting of the parts in turbocharger: Turbine wheel: made of thermostability alloy K418 coming from germany . Adopting electronic beam welding instead of Compression friction welding.Turbine housing: made of high temperature resistance spherulitic iron contain . nickel can be firmly working upon of 1000º Surface of turbin housing is beautified with high speed moving stainless-ball.Compressor housing: made of casting aluminium alloy has a high strength and high density.Delivery valve:contruled by high temperature resistance Fluorine- Silicon rubber film plate.at the Environment of 180°C, It can be work for 400, 000 cycle times saftily.Compressor wheele: made of casting aluminium alloy hase a good fuction of casting and high density, It can be intensity by heat treatment.Balance requirment:All of our turbocharger have been balanced with assembly's centre main-body part balance equipment. Unbalanced amounts must be lower than Our turbochargers have excellent function:high temperature resistance( exceed 1000ºC); Ultralow noise; Accurate balance(Unbalance lower than );And come true a long-life.We have enough profess
