Abstract
A metal casting method and a plastic injection molding method in which an insert is molded in molten material such that no molten material enters the interior of the insert. The usage of a wire thread insert as insert has the advantage that for example in an aluminum cast part thread holes can be produced already as part of the casting process. For this purpose, the casting mold, the insert, as well as the casting method are described.
