Gravity Die Casting
In addition to the high pressure die casting process, we also cast silicon tombac, brass and copper using the gravity die casting process.
High pressure die casting is particularly suitable for thin-walled components with a high required accuracy of reproduction. Gravity die casting is usually used for voluminous components with a comparatively large casting weight.
