Abstract
A die cast component includes an insert element with a plurality of form-fitting elements which are designed for the form-fitting connection of the insert element with a casting material. A ratio of a component wall thickness to a wall thickness of the insert element is a maximum of 4.
Claims12
A die cast component, comprising:
- a metal or metal alloy casting material;
- and
- an insert element, wherein the insert element has a plurality of form-fitting elements which are arranged homogenously or in a uniformly distributed manner in the insert element and which are configured for form-fitting connection of the insert element to the casting material, wherein a ratio of a wall thickness of the die cast component to a wall thickness of the insert element is at most 4, wherein the form-fitting elements are round holes, and wherein the round holes have a diameter of 2 to 8 mm.
A casting method for producing a die cast component having an insert element, comprising the acts of:
- forming the insert element such that an infiltration, a form fit and/or a micro-form fit is achieved with a metal or metal alloy casting material, wherein the insert element has a plurality of form-fitting elements which are arranged homogenously or in a uniformly distributed manner in the insert element, wherein the form-fitting elements are round holes, and wherein the round holes have a diameter of 2 to 8 mm;
- and
- encapsulating the insert element with the casting material such that an encapsulating wall thickness of the casting material is less than 2.5 mm, and wherein a ratio of a wall thickness of the die cast component to a wall thickness of the insert element is at most 4.
