Abstract：
Using the DISA vertical molding line, management from two aspects of foundry process innovation and manufacturing process control;The mould technology of ductile iron crankshaft for air conditioning compressor was designed, the structural design of spheroidized lining was improved. The results show that the rapid pouring is realized, the reaction time of nodular iron is delayed, and the nodular iron crankshaft with stable internal quality is mass produced with the nodular iron level controlled at level 1-3, nodular rate 80%.
