Our solutions


Powder metallurgy is an ideal technology for manufacturing gears because it creates the geometry of the teeth directly in the compacting operation. Powder metallurgy gears of different shapes, sizes and profiles are produced of metals with different alloying grades or stainless steel base , finished with heat treatments (case hardening, carbonitriding, induction hardening, steam treatment) . We can OEM&ODM :spur gear, internal gear, bevel gear, planetary gear, double gear, motor gear, gearbox, drive gear, gear hub, gear ring, oil pump gear etc.

Auto parts

Jingshi are engaged in the manufacture and sale of sintered metal components since 2014, passed TS16949 Certificate. with high accuracylow cost of powder metallurgy parts and superior performance,the application of powder metallurgy parts in automobiles is becoming more and more widespread. Auto parts: pulley , camshaft parts, oil pump rotor and stator, bushings, clutch hub, auto transmission,chassis parts, drive line parts, car accessories etcs. Welcome to consult with your drawing and samples.

Stainless steel parts

Jingshi produce the powder metallurgy stainless steel series parts which have the advantages of close to net shape, high dimensional accuracy, and high material utilization rate to be widely used. With all the property sintered stainless steel parts are be used in various metal precision parts, powder metallurgy gears, oil bearing, machinery, chemical industry, ships, automobiles, instrumentation and other industries. Gears produced by 304 stainless steel powder metallurgy have good non-magnetic, corrosion resistance and comprehensive properties. 316 stainless steel powder metallurgy, the parts produced have corrosion resistance and high temperature resistance, such as: Electro-hydraulic control system parts
