ADC12 Die Casting Drive Arm Crank

Agriculture machines Apparatus Part of High Precision CNC Machining, the part has small wall thickness, meanwhile, the part have structure of small cavity, which usually easily cause problem of mold sticking, pull mark etc. this part carried Die Casting standard of Grade GB-CT4, 

The part has requirement of surface finish of E-Coating, which has process of curing in hot thermal oven, the temperature usually be up to 170-200 degree, the porosity mentioned above will expand and get out from the part, result in pits and bubbles on the coating.  So in the inspection work instruction, there is request that the  QC inspector should fracture the part with hammer, then check the section particle with magnifying lens to see if there is problem of porosity on the section. The inspector also will make a record of the part weight, and control through weighing the part. All these action is to avoid batches rejected while e-coating.
