It provides smooth stepless speed control from 50 to 1400 rpm, with fine adjustment in 10 rpm increments, ensuring stable and flexible operation for different jewelry molds and design requirements.

Centrifugal Casting Principle: High-Precision Jewelry Forming

After molten metal is poured into the mold inlet, the mold rotates at high speed, generating strong centrifugal force that pushes the metal evenly into all areas of the mold cavity. This ensures excellent mold filling, producing jewelry pieces with smooth surfaces, clear contours, fine detail reproduction, and reduced porosity for higher-quality finished products.

Simple Structure & Easy Operation

With a straightforward mechanical design, the machine is easy to operate, maintain, and learn. Its durable construction ensures long service life and stable performance, making it suitable for both experienced operators and beginners in jewelry casting production.

High Cost-Performance Choice for Small-Scale Production

With its low investment cost, reliable performance, and flexible operation, this manual centrifugal casting machine is an ideal entry-level solution for businesses or workshops looking to start or expand small-scale zinc alloy jewelry production without high automation costs.
