The gravity die casting
Our casting technologies
Precise casting technology: Gravity die casting
The perfect precision casting technique between sand casting and aluminum die casting: gravity die casting. This casting process is primarily characterized by its cost-effectiveness. Its investment costs are significantly lower than those of aluminum die casting, and at the same time the use of permanent metal forms is more productive than manufacturing workpieces using the sand casting technique. As a result of these and other excellent properties, gravity die castings made of aluminum are used in many industrial sectors.
Aluminum gravity die casting process: Custom casting parts
In the aluminum gravity die casting process, the molten aluminum is poured into a
permanent metal mold via a sprue. The cavity of the so-called permanent mold is filled
solely by the influence of gravity. Due to its utmost thermal conductivity, the mold
accelerates the cooling of the molten aluminum in the solidification process. The rapid (and controllable) solidification means that gravity die castings have a particularly fine grained and dense microstructure. Compared with sand casting in particular, gravity die castings are characterized by a very smooth surface. As a result, they exhibit better
mechanical properties compared to similar components made of aluminum, possess
exceptionally high dimensional accuracy, and impress with their precise contour
reproduction. In addition, this technique also provides the possibility to form undercuts
using sand cores.
Advantages of the gravity die casting technique
- reusable casting molds, suitable for large quantities
- cost-effective reproducibility with consistent quality
- smooth surfaces & ideal mechanical properties of the parts
- possible weight per unit of up to 40 kg
- high profitability
