A die provided for fixing a porous ceramic insert for producing a light metal component which is reinforced by the insert. For this purpose, the insert is positioned in the die in such a way that any force which occurs for the purpose of fixing the insert is compensated for by a collinear force, which minimizes the bending moments exerted on the insert. Furthermore, shielding elements are used to protect the insert from a casting metal flowing into the die. Furthermore, the invention describes a process in which the velocity of a casting plunger which moves the casting metal into the die is regulated in such a way that the insert is not damaged by the kinetic energy of the casting metal. This is achieved by filling the die at a low velocity until the metal has flowed around the insert. Then, the casting plunger is accelerated, thus ensuring optimum filling of the die with the casting metal.
