Choose the traction arrangement for the shape and handling limits of your product.
Compare belt, caterpillar, roller and precision haul-off arrangements for extrusion. Specify the product shape, speed range, contact surface and control signals.
A haul-off draws the extruded product through the downstream process at the required operating speed. The traction arrangement must suit the product geometry and the surface condition after cooling. The equipment range includes double-track, multi-caterpillar, belt, roller and precision configurations, with custom arrangements reviewed for the application.
Choose the contact arrangement before focusing on drive size. A large rigid pipe, a thin profile and a flexible tube can require different contact lengths, pressure settings and support. The connection to the cutter or winder is also part of a practical specification.
Design And Function
What The Machine Does On Your Line
01
Several traction arrangements
Compare the available traction arrangements against the section and material being handled. The appropriate contact arrangement is determined by the product, not by machine appearance.
02
Surface contact review
Specify acceptable marking and deformation along with the product dimensions. Contact material, pressure and support should be considered together.
03
Coordinated downstream operation
Define how speed is set and how the haul-off exchanges signals with the cutter, extruder or winder. Include the retained control arrangement in a retrofit.
This video shows QTech-Machinery’s complete nylon tube extrusion line running after installation and commissioning. The line includes an SJ65/28 single screw extruder, customized tube die, vacuum calibration tank, immersion cooling tank, servo belt haul-off, rotary flying knife cutter, conveyor, and automatic collection system.
Viewers can see the full production process from nylon material plasticizing to tube forming, cooling, traction, online cutting, and finished tube collection. It is a practical reference for manufacturers looking for nylon tube extrusion equipment, PA tube production lines, or automatic plastic tube cutting solutions.
Watch QTech-Machinery’s tumbler straw extrusion line for THERMOS, producing LLDPE and PCT reusable straws with automatic feeding, extrusion, cooling, servo cutting, chamfering, and V-shape opening.
Watch this video to see a complete Φ20–Φ110 mm HDPE pipe extrusion line supplied by QTech-Machinery for PE100 water supply pipe production. The line includes automatic feeding, SJ75/33 extrusion, color stripe co-extrusion, vacuum calibration, spray cooling, servo haul-off, cutting, winding, and stacking.
It is a practical reference for customers looking for a reliable HDPE pipe extrusion line manufacturer in China.
A complete HDPE pipe extrusion line is not just one extruder. It is a coordinated production system that includes material feeding, drying, extrusion, co-extrusion, die tooling, vacuum calibration, cooling, haul-off, cutting, winding or stacking, electrical control, spare parts, and technical documents. For manufacturers planning to produce PE100 water supply pipes, irrigation pipes, cable protection pipes, […]
Nylon tubes and PA tubes are produced by a complete nylon / PA tube extrusion line, not by a single standalone machine. A professional production line normally includes material drying and feeding, a single screw extruder, customized tube die, vacuum calibration tank, cooling tank, servo haul-off, online cutting machine, conveyor, and automatic collection system. For […]
Choosing the right tumbler straw extrusion line is not only about buying an extruder. It is about matching material, straw size, output, cooling, cutting, finishing, automation, and supplier support with your real production needs. For reusable tumbler straw production, especially for drinkware brands, the line must handle small-diameter tube extrusion with stable sizing and clean […]
Need an answer for your own material or product? Ask Maggie directly.
Which haul-off type should I select?
Begin with product shape, size, rigidity and surface requirements. Belt, caterpillar and roller arrangements should be compared against those conditions.
Will higher clamping pressure solve slipping?
Not necessarily. Contact condition, cooling, alignment and traction length also matter. Excess pressure can deform or mark the product.
Is the stainless steel servo configuration standard?
That construction and drive combination is a custom arrangement. Define construction materials, drive and traction arrangement in the specification for your machine.
