The broken bar problem of the cast aluminum rotor was solved by replacing side gate with minimum pressure loss multi-point gate.The laminated torsion of the rotor core had been completed perfectly by using the core shaft torsional skew key.By selecting full vertical die casting machine and adopting one die four cavity rotor casting die

the placement speed

smoothness and production efficiency of the iron core inserts were improved.The rotor casting die had the advantages of simple and practical structure

reliable work

low manufacturing cost

convenient operation and low scrap rate of castings.
