More freedom of design
Rigid tooling, rigid sliders. The limitation in design in high-pressure die casting does not come as a surprise. That is why in general only open profiles can be produced, which may yield towards the open side under stress. In sand casting in contrast, sand cores can be used to create undercuts, which allows maximum freedom of design in the development of components and the production of highly rigid closed profiles. High-pressure die casting suppliers are currently experimenting with salt cores in order to catch up on sand casting. However, due to the high reactivity of salt, it has so far not been possible to ensure process reliability.
