The present invention relates to an arrangement for low-pressure casting of refractory metals, with a furnace chamber with one or a plurality of gas supply openings () and gas outlet openings (), and a riser pipe () through a cover () of the furnace chamber, a melting container () for the refractory metals arranged in the furnace chamber, and a heating device for heating the refractory metals in the melting container (). In the proposed arrangement, the melting container () is formed as an exchangeable insert for a receiving mould () supporting the melting container (), which is arranged in the furnace chamber, wherein a thermally insulating layer () is formed between the receiving mould () and the melting container (), or is integrated into the melting container (). With the proposed arrangement, a quick and easy exchange of the melting container for different alloys can also be carried out in the low-pressure casting of refractory metals.

Arrangement for low-pressure casting of refractory metals

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.
