Semi-Automatic Vacuum Centrifuge Machine Zinc Alloy Jewelry Production Equipment

Semi-Automatic Centrifuge Machine Zinc Alloy Jewelry Production Equipment 

Semi-Automatic Design: Improved Efficiency & Stable Operation

This semi-automatic vacuum centrifuge machine is specially designed for zinc alloy jewelry production. The semi-automatic structure reduces manual labor and improves overall production efficiency. Compared with manual equipment, it eliminates frequent manual opening and closing operations, making the casting process smoother and more suitable for continuous industrial production.

Wide Application in Jewelry Manufacturing Industry

The machine is widely used for producing zinc alloy jewelry such as rings, earrings, pendants, bracelets, brooches, and other precision fashion accessories. It is suitable for both customized small-batch production and medium-scale industrial manufacturing.

High Vacuum System: Reduced Defects & Better Surface Quality

Equipped with an imported high-performance vacuum pump, the machine ensures stable vacuum pressure during operation. The vacuum system effectively reduces air bubbles, porosity, and internal casting defects. It also improves metal flow and mold filling performance, resulting in smoother surfaces, sharper details, and higher-density jewelry products.

Vacuum-Assisted Casting: Faster Production & Longer Mold Life

The vacuum function not only improves casting quality but also accelerates the molding and cooling process. Strong vacuum airflow shortens solidification time, increases production efficiency, and reduces cycle time. At the same time, it reduces thermal stress on molds, helping extend mold service life and lower long-term production costs.

Precise Speed Control: Stable Rotation & Digital Monitoring

The machine features a precise centrifugal speed control system with a digital display for real-time monitoring and parameter adjustment. Stable rotation ensures consistent centrifugal force, improving casting repeatability and ensuring uniform quality across different jewelry designs.
