YONGHANG supplies Haul-off belts for all types of extruders, including caterpillar haul-off for cables, wires, pipes and profiles.
Haul-offs” are pulley-driven parallel belts that contact opposite sides of in-process products, usually by means of rollers exerting suitable pressure for the belts to grip and haul them, with the desired controlled pulling action.
Our range includes specific combination of base belts, tensile strengths and fabrication details to meet technical requirements of variety of extrusion applications, including specific resistance, hardness, temperature, friction needs.
