Features:
Specially made for round filter cage production. 
1.High precision: intelligent "S" shape speed curve, the encoder and the servo motor form a closed-loop wire feeding control system, secure a diameter tolerance less than 0.25mm, eventually solve the ring precision issues inherent in the traditional mechanical or hydraulic ring making machines.
2.High stability: wire feeding unit is driven by two motors directly without gears, belts or other transmission parts which would get less precise due to wear-out.
3.Easy operation: ring size is adjusted by turning the wheel, much easier than traditional mechanical or hydraulic machines.
4.User friendly UI, the counter always shows the amount of rings formed.
