Abstract: In a method for manufacturing lamination stacks of controlled height in a tool, starting material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.

Abstract: The stack of laminations consists of punched laminations (5), which are bonded together by an adhesive agent. The adhesive agent is composed of an adhesive (4) and an initiator (15), which consists of methacrylates, derivative imines and methacrylic esters. The completely cured adhesive bond has long-term resistance when exposed to a temperature of at least over 80° C. The adhesive (4) is applied over the full surface area and in a contacting manner to one side of the lamination (5) and the initiator (15) is applied to the same side and/or to the other side of the lamination (5). The initiator (15) reacts with the adhesive (4) when contact is made and establishes the adhesive connection between laminations (5) lying against one another. The adhesive agent may, however, also be an adhesive (4) that cures by itself when heat is applied.

Abstract: In a method for producing cast components for electrical applications, a hardenable aluminum alloy is melted and filled into a die casting mold. The melted aluminum alloy is cooled by the die casting mold that is comprised of a material that has a thermal conductivity causing the melted aluminium alloy to be cooled at a cooling rate of approximately ?5×102 K/s. Prior to filling, the melted aluminum alloy is introduced into a fill chamber and the melted aluminum alloy is displaced at a minimal displacement speed within the fill chamber.
