Based on ensuring the quality of the products,the pressure and injection speed was decreased,so the die casting machine was selected from 12 000 kN to 8 000 kN,realizing the target of low cost.Through adopting the high vacuum technology,the vacuum valve and vacuum machine,the back pressure during the filling process was decreased effectively.The origination of defect was analyzed after changing the die casting machine tonnage by means of numerical simulation.By optimizing the gating and overflow system,the air pressure was reduced,meeting the requirement of customer.
