Liberate the working people of the world with automated machines, starting with fully automatic stone setting machines.
In fact, the machine is roughly composed of three major systems: Motion Mechanism, Controlling system, Pneumatic system.

A ball screw is a mechanical device that converts rotary motion into linear motion with high efficiency and accuracy. By installing ball screws and servo motors on different axis positions, precise movement on different axes, Moving, reversing products and moving the nozzle can be easily achieved.

The robotic control system working like this: The teach pendant enables positioning and machine programming, while motor controllers drive precise actuator movements. An industrial PC synchronizes parameters between these units, ensuring seamless command execution and motion calibration.

The pneumatic system facilitates stone picking and placing using nozzles and air circuits. Precise airflow regulation through electromagnetic valves and sensors ensures accurate positioning. This enables reliable suction during pickup and controlled release at designated placement points.
Designed for wax stone setting, it has 8 nozzles in total and can be operated by one or two people. The stone setting efficiency is about 24,000 stones per hour.


Suitable for the stone setting process of imitation jewelry. Equipped with eight nozzles and eight syringes, glue is dispensed first, then stone setting. It can also be used for stone setting process of watches, mobile phone cases, hairpins and other products, with an efficiency of 28,000 stones per hour.
