Full iron cable mandrels are composed of two side plates and a cylinder, with some models requiring two shaft sleeves and a conduit inside! They feature high strength, great rigidity, and after machining and dynamic balance inspection, they offer smooth operation at high speeds. They are widely used in equipment such as drawing machines, twisting machines, extruders, cable-making machines, and armor-winding machines, as well as in processes like handling, delivery, and annealing.
