In precious metal jewelry production, defects such as porosity, sand holes, incomplete pattern reproduction, oxidation discoloration and insufficient filling have long restricted finished product yield, raising precious metal loss and rework costs. The Hasung vacuum pressure jewelry casting machine integrates vacuum protection, induction melting and pressure pouring technologies. It is suitable for casting gold, K gold, silver, platinum, palladium and other precious metals. Featuring stable equipment performance and excellent casting results, it is the preferred casting solution for jewelry studios, jewelry processing factories and branded jewelry manufacturers.
