A metal component is produced using a casting-and-forming tool by casting a melt of a metal alloy into the casting-and-forming tool, wherein the melt is poured from above into a base part or reservoir of the casting-and-forming tool at a first pressure, applying pressure to the melt between the base part and an upper part while the melt is solidifying to a component, wherein the solidifying melt is pressurized at a second pressure, which is larger than the first pressure, when the melt is at least partly, i.e., mostly solidified to form a component compressing the component by relative movement of the base part to the upper part so as to compress the component with a third pressure, which is higher than the second pressure.

Hydro forming method for constructing a piece of vehicle wheel rims. The whole process will be implemented in seven stages. As the first station of raw sheet by the form Stretch a piece of cylindrical internal diameter sized the smallest inner diameter and the 1.6 height rim and this diameter is larger than the outer rim diameter. Secondly outer rim diameter cylindrical piece is the desired size trim. In the third and main stage action takes place hydro forming cylindrical piece by piece into a specific form of work (work piece) with no Punches final form and elasticity are required.
