On our caterpillar haul-off units, we provide the optimal solutions for the customer’s needs with the advantage of flexibility in pad dimensions and track lengths. Our haul-offs are equipped with two independent tracks with gearboxes with continuous speed adjustment by inverter.


Flexibility in pad dimensions

Two independent tracks with gearboxes

Speed adjustment by inverter

Product Range

Pad width range from 220 to 500 mm

Tracks length from 1400 to 2000 mm

Extrusion offers two types of cutting units for profile applications: Saw (TK-series) and guillotine (GK PRO) cutting systems. Depending on the customer’s preference, we can install these units in our integrated haul-off and cutting combination or supply separately. As option, for window sill and similar wide panel profiles, we also supply cross-cut system (CC PRO) for cutting profiles into smaller measurements in width. In addition to these units, our blade cutting unit (BK-series) is ideal for cutting profiles with a max. height of 8 mm, without any dust and chips.

The complete extrusion consists of following items:

  • Conical Twin Screw Extruder:

It is used for melting and stirring plastic material. LANGBO adapts special screw and barrel type that provide perfect mixing and homogenous. We use special gear box for the Extruder which has axial bearings. Transfer the motor to the screw. For minimizing electricity consumption, we use the famous brand of driving motor of “SIEMENS” on our Extruder. Automation system designed with PLC and touch panel controller can be selected.

  • Mould:

Our mould designing gives ideal viscosity to melt material for profile producing. It gives profile or shape to plastic after processing. All faces the plastic in contact with is polish, so that frication losses minimized.

  • Calibration Table:

The shaped profile that come from mould is subjected to calibration and cooling processing on the calibration table. The designing of calibration table varies according to the type and characteristic of the profile. The area that contacts with water is made of stainless steel in order to prevent corrosion.

  • Caterpillar Haul-off:

The designing of caterpillar haul-off changes depending on the contact area that is related to the profile measurement. The inverter control is standard on all caterpillar haul-off. For this reason, as the speed can adjusted with respect to material output rate. The caterpillar haul-off is also capable of making measurement adjustment through speed control equipment.

  • Saw cutter:

In the speedy working condition, profile saw works with high efficiency in term of cutting frequency. As the saw table and clamps move synchronously. The saw cuts the profile in required length.

During the cutting processing, swarf and dust appears, in order to prevent these in production area, there is a dust collection unit is integrated in saw cutter. This unit absorbs swarf, dust effectively and removes to storage.


  • Tip-off unit:  It operates on pneumatic cylinder.

Our extruder lines allow our clients to produce a wide range of PVC and WPC profiles with the following specifications::
