Ingot melting and powder metallurgy gears are powder metallurgy parts commonly used in various automobile engines, which can fully meet the requirements of dimensional accuracy, especially tooth shape accuracy, through one-time molding and finishing process without other post-processing processes. Therefore, compared with traditional machining methods, the material input and manufacturing are greatly reduced, which is a typical product that reflects the characteristics of powder metallurgy. Examples of powder metallurgy parts supporting supporting category parts name: automobile engine; camshaft, crankshaft timing pulleys, water pumps, oil pump pulleys, active and driven gears, active and driven sprockets, cams, bearing caps, rocker arms, bushings, thrust plates, valve guides, intake and exhaust valve seats automobile transmission; a variety of high and low-speed synchronizer hubs and assemblies, clutch gears, cams, camshafts, sliders, shift rods, shaft sleeves, guide blocks, synchronizer rings, gears and components, clutch gears, cams and camshafts.
