Vacuum Semi-Automatic Casting Machine Equipment Badges Medals & Fashion Zinc Alloy Necklace

Product Description

The Vacuum Semi-Automatic Casting Machine is specially designed for producing badges, medals, and fashion zinc alloy necklaces. By combining vacuum technology with semi-automatic casting control, the machine ensures high-density, bubble-free, and precisely detailed metal products. It is widely used in jewelry workshops and precision metal casting factories for small to medium batch production.

Working Principle

The machine melts zinc alloy in a temperature-controlled crucible until fully molten. During the casting process, a vacuum system removes air from the mold cavity to reduce porosity and improve casting quality. The operator then activates the semi-automatic centrifugal or casting cycle, allowing molten metal to fill every detail of the mold under controlled conditions.

This process ensures excellent mold filling capability, resulting in castings with a dense internal structure, clear contours, fine detail reproduction, reduced porosity, and improved surface finish.
