This pump housing is an aluminum die casting parts that used for motorcycle As a high quality die casting manufacturer, we produce this parts over 200,000 pcs per year according to customer’s specification.
It looks like a pretty simple parts. However this parts has strict quality requirements for mechanical strength and oil sealing. Therefore we must use first-class A380 material and perform strict dimension control while production. After die casting process, we have to rework some of features by CNC machine. The tight tolerance is only +/-0.02 for distance dimension, and +/-0.01 for shape features.
