Abstract
Tlačno lijevani odljevci nemaju sasvim homogenu strukturu. Legure u rastaljenom stanju sadrže plinove i oksidne uključke koji mogu izazivati mikropukotine te poroznost kod gotovih odljevaka. Ako se od neke komponente očekuje sposobnost zadržavanja nekog medija (vode, zraka, ulja i sl.), zahtijeva se kontrola propusnosti medija kroz stijenke. Za kontrolu propusnosti tlačno lijevanih odljevaka izrađuju se posebni namjenski uređaji. U okviru rada opisan je proces tlačnog lijevanja i konstrukcija kalupa za tlačno lijevanje aluminijevih legura. Opisano je kako parametri lijevanja utječu na pojavu propusnosti i koje se još greške na odljevcima mogu pojaviti. Navedene su metode pomoću kojih se ispituje poroznost odljevaka, a na kraju je dan osvrt na ukupne troškove proizvodnje. Teorijska analiza potkrijepljena je primjerom iz industrije. U zaključku je ukratko objašnjeno koje teme su se obradile u radu i dodani su prijedlozi kako se optimizirao promatrani postupak lijevanja.
Abstract (english)
Die castings do not have a completely homogeneous structure. Alloys, while in a molten state, contain gas bubbles and inclusions that can cause microcracks and porosity in finished castings. If a component is expected to retain a medium (like water, air, oil, etc.) its leak tightness control through the walls is required. Special devices are built to control the leak tightness of die castings. The thesis describes the process of die casting and the design of molds for die casting of aluminium alloys. It was described how the casting parametres affect the leak tightness and which other defects can occur in castings. The methods used to analyze the porosity of castings were listed and at the end, an overview of the total production costs was given. Theoretical analysis was supported by an example from industry. In the conclusion, it is briefly explained which topics were covered in the paper and suggestions were added to optimize the observed casting process.
