Easy-Laser E930 - Extruder

Easy-Laser® E930 is designed to measure straightness and pointing direction, primarily on extruder pipes. Another application can be hydraulic pipes, for example.

An aligned extrusion machine leads to:

  • Less wear on the extruder screw and tube,
  • Even quality on the produced material,
  • Increased machine availability.

Measurement system for alignment of extrusion machines

With the Easy-Laser® E930 system, pipes with diameters down to 50 mm can be measured, at a range of up to 40 m. The transmitter's laser beam can be compared to an absolutely straight and weightless ruler, that is to say a perfect starting point for precision measurement.

During the alignment procedure both detector and spindle are rotated, thus self-calibrating the system. This way you can determine how the centerline of the spindle is, relative to the tube’s center at the inlet end.

Document your measurement results

The detector's measurement value is transferred to the display unit wirelessly, which means that one can measure more freely. The measurement system has programs that guide you step-by-step, using clear graphics on a large 5.7" color screen. You can also produce full documentation for your measurement job, with the direct generation of PDF reports, and database programs for PC for example.

Many reasons for alignment

The gearbox shaft center must coincide with the centerline of the extruder tube. Otherwise, the screw at the inlet’s end will be pressed against the tube, which will lead to abnormal wear of both screw and tube along with increased energy consumption. This wear can also result in metal fragments in the produced material. It is important that the extruder tube is straight so that the screw does not rest against the tube in any part, which can result in abnormal wear and fragments of metal in produced material. We will also get a more even temperature of produced material which in the end results in a better product.

Complete system with all the measuring programs

Easy-Laser® E930 is a complete system in itself, with a laser transmitter, detector, and display unit. You can also add other parts from our extensive range to build a system that suits your specific needs and requirements because all the measurement programs are included as standard. For example add shaft alignment equipment for other rotating machines, and lasers for flatness measurement.
