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.
