Left: the original gravity die casting and right: final high pressure die casting designs, which reduced material usage by 2.5 kg


from gravity diecasting to high pres-sure diecasting. The casting weight was reduced from 9.5 kg to 7 kg, and the runner and gating sys-tem was optimized with the help of Magmasoft simulations. At the beginning of the project, a prototype sample


casting was provided by the customer that weighed 9.5 kg with a minimum wall thickness of 10 mm. The Endurance engineers’ first objective was to reduce the casting weight and optimize the process productivity. To fulfill this requirement, the casting design had to be modified after studying the solidification pattern using Magmasoft simulations. Although the original prototype sample was produced in a gravity diecasting process, En- durance proposed to change the manufacturing process to high pressure diecasting. After gen-eral approval, the casting model was jointly modified to meet the manu- facturing requirements of the HPDC process. Using Magmasoft simulations, the casting weight could be reduced by 2.5 kg by minimizing wall thickness and mass accumulations at pockets and ribs in appropriate areas. Changing the manufacturing process to high pressure diecasting led to increased productivity by reducing cycle

左:原重力金属型铸件,右:最终的压铸件设计将材 料用量减少了2.5 kg


7kg,浇道和浇口系统也借助于MAGMASOFT模拟系 统得到了优化。


在项目的开始,先把重量为9.5kg、最小壁厚为 10mm的原型样件提供给客户。Endurance公司工程 师的首要目标是减轻铸件重量,优化生产率。为了满足 要求,必须在使用MAGMASOFT模拟软件对凝固形态 进行研究之后,改进铸件的设计。虽然最初的原型样件 采用的是重力金属型铸造工艺,但是Endurance公司提 议将生产工艺改为压铸。提议得到一致同意之后,联合 修改了铸件模型以满足压铸的生产要求。采用MAG- MASOFT模拟系统,通过将壁厚降到最薄,并且尽量减 少某些部位凹陷处和加强筋的金属聚集,使铸件重量减 轻了2.5 kg。


将生产工艺改为压铸,提高了生产率。由于缩短了作 业循环的时间,减少了转运和机械加工的时间,提高了
