Dimension of extrusion profiles

Non-contact cross-section measurement of profiles, pipes, hoses

The early knowledge of the profile dimensions, such as height, width, gap dimensions, … helps to timely counteract a reject production in the extrusion. If a measurement system is easy to operate, to set into operation as well as being reliable and not being vulnerable to material position changes, then extrusion has a powerful tool in hand. Height, width, gap dimensions, diameter of extrusion profiles are measured without contact inline by cross-section light scanner. The cross-section light sensors measure accurately, are maintenance-free and permanently calibrated.

Typical application data:

  • Measurement of profiles after extrusion, before or after calibration, before cutting
  • Production speeds: typically up to 60 m / min
  • Problem with contact measurement devices: only sample inspection possible, accuracy: +/- 0.1 mm
  • Measurement accuracy with non-contact cross-section measurement BDM: typical: 0.01 mm
  • Amortization: 2 months, integration of the measuring system into the existing system technology

Material examples:

  • Extruded profiles of hard and soft plastic as well as co-extrusion and tri-extrusion
  • Materials: PVC, ABS, PP, PC, PMMA, ASA and TPU
  • Products: Cable ducts, power guides, sealing profiles, pipes, hoses, corrugated pipes, …

Machines equipped with non-contact cross-section measurement:

  • Extrusion lines, calibration lines, …
  • Drawing lines, …
