Tilt casting

from Wikipedia, the free encyclopedia

Tilt casting is a group of process variants of permanent mold casting .

With tilt casting, the sprue side of the casting mold is inclined to the side at the start of casting. The mold or, alternatively, the entire casting system then rotates around one or more defined axes during the casting process.

This results in a calm, turbulence-free and foam-free mold filling. In addition, all areas of the mold cavity are fed evenly . Since the mold part contour part, as in this way gating system can be used, and the runner takes over the function of the feeder part, less falls recycled material to in comparison to conventional die casting. Another advantage is the controlled solidification of the melt .

Tilt casting processes are used in particular for the production of cast parts made of aluminum alloys , since these have a particularly strong tendency to form oxides and foam, which can be controlled and significantly reduced by tilt casting. Accordingly, the tilt casting process is often used, particularly in automotive engineering , for example for the production of cylinder heads and crankcases . Along with the use of more lightweight components in automobiles, in particular in the form of aluminum components, the tilt casting process has become increasingly important for the production of further parts of the chassis . Tilting casting processes are suitable for large-scale production and can be used relatively inexpensively for high quality and demanding cast parts.

Many tilt casting processes are protected by patent . The best-known examples of this are the Rotacast process and tilt and turn casting, patented by the Mexican automotive supplier Nemak as the Nemak Dynamic Casting Process .
