Cost-Effective Entry-Level Solution

This manual centrifugal casting machine is a practical and economical solution for small to medium-scale metal casting production. Specially designed for manufacturing zinc alloy letter pendants and fashion jewelry, it combines reliable casting performance, a durable mechanical structure, and low operating costs. Compared with semi-automatic and fully automatic centrifugal casting machines, it requires a lower initial investment while delivering stable, high-quality casting results.

Designed for Letter Pendant & Fashion Jewelry Manufacturing

This machine is specially developed for producing zinc alloy letter pendants, alphabet charms, necklaces, bracelets, earrings, rings, brooches, jewelry accessories, decorative ornaments, keychains, badges, souvenir coins, garment accessories, and other precision zinc or lead alloy products. Its versatility makes it suitable for jewelry manufacturers, fashion accessory suppliers, and metal craft workshops.

Variable Frequency Speed Control & Electromagnetic Braking System

The machine adopts AC variable-frequency speed regulation with an inverter, DC speed adjustment, and an electromagnetic braking system. It provides stepless speed adjustment from 50–1800 rpm, with precise 10 rpm increments, allowing operators to optimize casting speed according to different mould sizes and product structures.

High-Precision Centrifugal Casting Technology

During operation, molten zinc alloy is poured into the mould sprue while the mould rotates at high speed. Powerful centrifugal force ensures complete mould filling, allowing intricate letters, delicate patterns, fine textures, and thin-wall structures to be accurately reproduced. The finished castings feature smooth surfaces, sharp details, dense internal structures, excellent dimensional accuracy, and minimal porosity.

Simple Operation & Reliable Performance

The machine features a compact and durable mechanical structure that is easy to install, operate, and maintain. Stable rotational performance ensures consistent casting quality while reducing production costs, making it suitable for continuous daily manufacturing.

Ideal for Startups & Small-Scale Jewelry Production

With its affordable investment, reliable operation, excellent casting quality, and outstanding cost-performance ratio, this manual centrifugal casting machine is an ideal choice for jewelry workshops, startup businesses, and manufacturers producing zinc alloy letter pendants and fashion jewelry.
