Centrifugal Casting Machine for Zinc Alloy Belt Buckles Spin Casting Equipment

Cost-Effective Entry-Level Solution

This manual centrifugal casting machine is an economical and reliable solution for small to medium-sized metal casting production. Designed specifically for zinc alloy casting, it features a simple structure, stable operation, and low maintenance costs. Compared with semi-automatic and fully automatic centrifugal casting machines, it requires a lower initial investment while still delivering consistent casting quality, making it an ideal choice for startups, workshops, and growing manufacturers.

Designed for Zinc Alloy Belt Buckle Manufacturing

This machine is specially developed for producing zinc alloy belt buckles and various fashion hardware accessories. It is also widely used for manufacturing badges, medals, jewelry, brooches, keychains, souvenir coins, garment accessories, decorative ornaments, refrigerator magnets, pet tags, and other precision zinc or lead alloy castings. Its versatility makes it suitable for a wide range of decorative metal casting applications.

Variable Frequency Speed Control & Electromagnetic Braking

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 parameters for different mould sizes and product designs.

High-Precision Centrifugal Casting Performance

After molten metal is poured into the mould sprue, the mould rotates at high speed to generate strong centrifugal force. This evenly distributes molten zinc alloy throughout the mould cavity, ensuring complete filling of thin walls, sharp edges, and intricate patterns. The process produces castings with excellent dimensional accuracy, dense internal structures, smooth surfaces, clear details, and reduced porosity.

Simple Operation & Reliable Performance

The machine features a durable mechanical structure with straightforward manual operation, making it easy to install, operate, and maintain. Stable rotational performance ensures consistent casting quality while reducing production costs and minimizing downtime.

Ideal for Startups & Small-Scale Production

With its affordable price, reliable performance, easy operation, and excellent cost-performance ratio, this manual centrifugal casting machine is the ideal equipment for manufacturers entering the zinc alloy casting industry or expanding small-batch production of belt buckles and decorative metal accessories.
