ProCAST
直到第一个非模具零件最终成型,您才发现其中含有针孔、缩孔和热节。截止日期迫在眼前,您可以将零件寄出,但这必定会引起客户不快;您也可以选择返回设计阶段尝试找出问题、纠正问题并寄希望于最终可以去除缺陷。由于在铸件开发计划中低估了试验期,因此必须在进入试制阶段之前,确保浇注设计可以经受流程变动、保持稳健。
仿真使用户可以在开发阶段早期进行虚拟测试。为了在生产试制阶段得到理想的产品,必须准确预测和量化缺陷和工艺设计。
借助 ESI ProCAST,您每一次都可以铸造出正确的零件,包括第一次——在满足截止期限同时避免因报废零件或设计返工而浪费成本。几十年来,客户一直将 ProCAST 视为铸件基础操作(充型、凝固和孔隙率预测)必备的工具。借助有限元技术,ProCAST 还可预测变形和残余应力等复杂问题,可全面应用于大多数铸造合金材料和大多数铸造工艺,如砂铸、压铸、精铸以及这类工艺相关的各类变体工艺。
ProCAST 的优势
- 在设计之初预测、分析、测量和/或量化常见的铸件缺陷(例如断层扫描中所测量的孔隙率)
- 模拟整个工艺——从进炉到最终铸造,再到捕获和跟踪所有物理特性。(例如从浇注系统开始,预测裹气,以预测早期的空气夹带)
- 在视角因数下综合计算辐射,以解决高温熔模铸造中常见的阴影效应
- 计算整个过程中的应力,包括铸件在模具内部的凝固过程和模具外部的冷却过程,以预测最终变形,并通过 3D 扫描仪进行测量,轻松完成评估
- 预测晶粒结构,包括等轴晶和单晶、微观结构和机械性能
- 通过 DOE、优化和工艺稳健性分析,自动确定铸件的工艺窗口,以实现最终的质量目标

Join our Casting LIVE Event on June 21st
Interested in hearing how ProCAST is essential to ensure getting casting parts right the first time, meeting deadlines, and cutting costs on scrap parts or late redesigns? With its finite element technology, you can predict complex issues like deformations and residual stresses and comprehensively address most castable alloys and most casting processes like sand castings, die castings, investment castings, and multiple variants associated with these processes. During an exclusive digital digital event, casting engineers from Kovolis Hedvikov, MCS, and Azterlan shared how they predict, analyze, measure, and avoid casting defects in the earliest stages of design.

砂型铸造厂成功的关键是优化浇注系统,并消除缩松的风险。ESI ProCAST 可以对全部砂型铸造工艺进行全面建模,包括高压造型线,这让用户能够研究冒口位置、过滤网、冷铁、保温冒口和发热冒口对铸造工艺和质量的影响。还可以研究包括充型、凝固和残余应力在内的不同因素。
ProCAST 的标准孔隙率模型还考虑了铸铁在凝固过程中的膨胀影响,以及铸型刚度对膨胀是否施加限制。更全面的方法含有运行耦合、热微观结构和孔隙率计算,包括孕育。微观结构求解计算可以计算不同相的演化并预测局部密度变化,从而提供更真实的孔隙率结果。我们可以针对不同铸铁提供具体的微观组织模型:GI、SGI、CGI 和 Ni-合金。
通过执行数轮生产周期获得稳态模具温度,重现车间条件,从而研究充型/凝固/保压压力、冷却水道设计和工艺参数优化。
压铸机参数信息集成在 ProCAST 内部,可实现实时冲头控制,从而准确选择合适的压铸机。我们可以对真空工艺和气体孔隙(原因包括未溶解的氢、铸件中的应力、模具移除和零件脱模时的应力释放,以及模具寿命)进行预测,以降低制造成本并评估使用中的零件性能。我们可以满足客户的具体需求,包括挤压、半固态材料、冷室的压射套筒模型、热室机器的鹅颈模型,以及低压压铸件的立管模型。ProCAST 可以对重力金属型铸造工艺(包括倾斜浇铸过程)进行建模,还可以自由定义轴和旋转速度。
ProCAST 可以自动生成代表模壳的网格,适用于精密铸造和壳型铸造工艺工艺。此外,ProCAST 还配有专用功能来满足精密铸造厂的特定需求,例如混合不均匀的外壳厚度并创建多个外壳层。同样,还可以考虑视角因数下的辐射,包括对高温合金至关重要的阴影效应。
