| Message: | Brief Introduction of oil pump vane rotor The vane rotor is used for rotary vane pump, positive-displacement pump, which consists of the vanes, inner rotor and stator (Pump housing). We manufacture it by sintering (Powder Metallurgy) technology, the sizes are provided by mould, powder pressing at first, sintering and then do coining. Density: 6.4-7.0 g/cm³Hardness: HRC 25-40Common material: DIN 30910 Sint C10 & D39DesignationFeCuCNiMoSint C10Balance1-5%＜0.3%Sint D39Balance1-3%0.3-0.9%1-5%＜0.6% For some types, we will do machining on two ends before final grinding to reach high precision, the possible runout of end surfaces can reach 0.03 mm, we grind the two ends by korean lapping machine. Quality control system of oil pump vane rotor: 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 url:http://www.dewin-powdermetallurgy.com |
