?Brief IntroductionOil pump stator is a basic component of oil pump, which co-work with the inner rotor or gear.We manufactured it by sintering (Powder metallurgy) technology.The advantages of PM stator are high efficiency, lower cost, more stable quality, because the sizes provide by mould.We do the finishing of two ends by korean lapping machine, the possible runout could be 0.03-0.05 mm.?Density: 6.4-7.0 g/cm3Hardness: HRC 25-40 Material: DIN 30910 Sint C10 & D39DesignationFeCuCNiMoSint C10Balance1-5%＜0.3%Sint D39Balance1-3%0.3-0.9%1-5%＜0.6%?Quality control system of oil pump stator:Work instruction paper and pictures at each working positionProcess flow card with each tray (Fully traceability)Sampling inspection and routing inspectionTS:16949 5 tools: PPAP, APQP, FMEA, SPC, MSADimensional report as per your requirement by CMM, projector, etc
