Hollow Ball Making Machine

The Sible hollow ball making machine is a fully automatic solution for producing hollow jewelry beads from flat metal sheet. It forms round balls, olive beads, abacus beads, tear-drop and custom-shaped beads from 1.5 mm to 14 mm in diameter — ideal for gold, K-gold, silver and copper jewelry production.

The machine automatically completes feeding, stamping and folding in one continuous cycle, delivering up to 120 beads per minute with uniform size and a smooth surface. With an intelligent auto pause-time adjustment based on tube length and an auto power-off delay function, it maximizes raw material usage and minimizes waste — one operator can easily manage multiple machines at the same time.

Key Features

Uniform Bead Output: Consistent bead length and smooth surface on every piece, with automatic pause-time adjustment based on tube length.

High Efficiency: Up to 120 beads per minute, significantly boosting daily output.

Simple Mold Change: Molds are compatible across all machine specifications; one operator can manage several machines at once.

Material Savings: Auto power-off delay reduces tube-end waste and maximizes precious metal usage.

Stable Long-Run Operation: Built for continuous factory-scale production without performance drop.

Wide Material Compatibility: Processes 14K, 18K, 24K gold, silver, copper, brass and K-gold alloys.

Compact & 220V-Friendly: Only 2.2 kW power, works with standard 220V 50Hz supply, saving power cost and installation effort in small workshops.
