Spin Casting Machine Zinc Alloy Metal Earrings Full Automatic Centrifugal Casting Equipment

Full Automatic Spin Casting Machine for Zinc Alloy Earrings

The Full Automatic Spin Casting Machine is specially designed for the mass production of zinc alloy metal earrings and other precision fashion jewelry. Integrating vacuum casting technology, intelligent PLC control, and high-speed centrifugal casting, this equipment delivers outstanding casting accuracy, stable production performance, and high manufacturing efficiency.

Compared with manual and semi-automatic centrifugal casting machines, the fully automatic system minimizes operator involvement, shortens production cycles, and ensures consistent product quality, making it an ideal solution for jewelry manufacturers and industrial casting facilities.

Designed for Zinc Alloy Earrings & Fashion Jewelry

This casting equipment is widely used for manufacturing various zinc alloy jewelry and decorative accessories, including:

• Zinc alloy earrings
• Stud earrings
• Drop earrings
• Hoop earrings
• Fashion rings
• Pendants
• Bracelets
• Brooches
• Jewelry charms
• Hair accessories
• Decorative ornaments
• Souvenir jewelry
• Small precision zinc alloy castings

The machine is compatible with silicone and rubber moulds, enabling the accurate reproduction of intricate patterns, fine textures, hollow structures, and complex decorative designs.

Fully Automatic

The equipment features an advanced PLC control system with an intuitive touch-screen interface. Operators can preset all production parameters, including vacuum time, rotational speed, casting duration, braking, and cooling cycle.

The fully automatic operation improves production efficiency, reduces manual errors, ensures consistent casting quality, and lowers labor costs, making it ideal for continuous industrial production.

High-Speed Centrifugal Casting Technology

During production, molten zinc alloy is poured into the mould sprue while the vacuum system removes trapped air from the mould cavity. The mould then rotates at high speed, generating strong centrifugal force that rapidly distributes the molten metal into every cavity.

This process provides excellent mould filling, minimizes porosity, shrinkage, and oxidation, and produces castings with dense internal structure, smooth surfaces, precise dimensions, and exceptional detail reproduction. It is especially suitable for manufacturing lightweight and highly detailed fashion earrings.

High Productivity & Reliable Performance

Built for continuous operation, the machine combines high-speed casting, intelligent automation, and durable mechanical construction.
