Applicable Products

This 4th generation fully automatic vacuum centrifugal casting machine is designed for efficient, stable, and high-precision production of fashion jewelry and small metal components. It is widely used for manufacturing:

Zamak hand bracelets, fashion necklaces, rings, earrings, pendants, charms, brooches, badges, souvenir coins, keychains, decorative ornaments, and other precision alloy jewelry products.

Applicable materials include zinc alloy (Zamak), lead alloy, tin alloy, and other low-melting-point metal alloys.

Working Principle (Fully Automated & Vacuum-Assisted Process)

The machine integrates the melting furnace and centrifugal casting system into one fully automatic production unit. The entire casting cycle is completed without manual intervention:

• Automatic melting and pouring of metal
• Automatic mold transfer into the rotating chamber
• High-speed centrifugal rotation starts
• Vacuum system actively removes air from the mold cavity
• Molten metal fills the mold under combined centrifugal force and negative pressure
• Automatic mold ejection after casting completion

This fully automated workflow eliminates manual ladling, mold handling, lid operation, and mold removal, enabling continuous and efficient production.

Core Advantages

1. Integrated Furnace & Casting System
The furnace and centrifugal casting system are integrated into one machine, eliminating the need for a separate furnace. This reduces equipment investment, saves workshop space, and improves production efficiency.

2. Fully Automatic Operation for Labor Reduction
From melting to mold handling, the entire process is fully automated. This significantly reduces labor intensity and ensures stable, repeatable production quality, suitable for mass production of fashion jewelry.

3. Vacuum System Improves Casting Quality
The vacuum system actively removes air from the mold cavity, greatly reducing defects such as bubbles, porosity, and incomplete filling. It is especially effective for intricate jewelry designs such as bracelets and necklaces with fine patterns and thin-wall structures.

4. Consistent Production Stability
Centrifugal force combined with vacuum pressure ensures stable mold filling, resulting in consistent product quality across large batches of production.
