Product Introduction
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.

FAQ
What is haul off extrusion ?
A Haul-off is engineered to consistently pull the profiles produced during the extrusion process. YongHangBelt provides two varieties of haul-offs: belt and caterpillar.
The double belt haul-off, used in PVC profile extrusion lines, is important for pulling profiles. By employing various rubber pads on caterpillars, the haul-off can accommodate profiles of different shapes. The device also features an adjustable draw-off speed tailored to the extrusion process.
What are the different types of haul-off ?
Haul-offs are available in various types, such as Belt, Double Caterpillar and Multiple Caterpillar. Each tailored for specific product diameters and production speeds. Belt haul-offs are well-suited for cables, pipes and wires with smaller diameters, typically ranging from 10mm to 32mm, especially in scenarios requiring high-speed production.
Alternatively, bigger diameter pipes require the use of multiple caterpillar haul-offs or double caterpillar haul-offs. Selecting the right haul-off unit for your specific production line is vital to prevent potential issues and ensure seamless production.
YONGHANG specializes in produce and custom coated transmission belts for 12 years.
