Lost Foam Molds

What Is Lost Foam Molds

---

Lost foam casting (also known as solid mold casting) is a solid mold casting in which foam plastic molds use dry sand without binders combined with vacuum technology. After drying, it is buried in dry quartz sand to vibrate and shape, poured under negative pressure to make the model gasify, and the liquid metal occupies the position of the model. The key to the success of lost foam mold casting is to understand the importance of the close cooperation between the casting manufacturer, the user and the mold designer. The Lost Foam mold designer must first meet the requirements of the user and the needs of the casting factory, and then meet the requirements of mold manufacturing and model forming.

The lost foam molds is of significant importance in lost foam casting operations, whether for prototype or mass production.

The Comprehensive Design Points Of Lost Foam Molds

EPC mold technology has many features that other casting methods cannot provide to produce castings – negative draft angle, insert casting, special structures (such as curved channels) and complex blind holes, etc. are all possible to cast. Description of key features of optimally designed EPC parts Detailed casting process analysis needs to identify some machining and casting related factors as well as casting, parting surfaces, gating systems and dimensional tolerances etc. A preliminary analysis of the mold cavity is guided by discussion . Part machining drawings are carefully reviewed in conjunction with casting drawings, which will help to integrate many factors into the design.
