达到了降成本的目标。通过使用高真空压铸工艺

应用真空阀、真空设备

减少了铝液填充过程的背压。借助模拟分析软件

分析了压铸机变化后缺陷产生的原因。通过调整浇排系统

实现了缺陷部位的气压降低

压铸件品质满足技术要求。

Abstract

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.
