This study presents research results of the influence that refining and transfer of AlSi12S alloy on the porosity of high pressure die-castings. Tests were conducted under production conditions of Die-casting Foundry META-ZEL Sp z o.o. The operation of refining was conducted in a melting furnace, with the use of an FDU Mini Degasser. Decay of the refining effect was assessed by evaluating the porosity content and metallographic examination.
