Combined measurement of length, diameter, gap size of profiles, hoses, pipes

complete dimensional checks of profile, tube production and extrusion lines

In the production of profiles, hoses and pipes, it is important to comply with different tolerances and to optimize or regulate the process with inline measurement values. If lengths, diameters, gap sizes of such semi-finished products are checked by hand and random sample inspection, the test is not only labor-intensive and person-dependent but in many cases even critical under the aspect of work safety and increasingly inadmissible. The solution is combined of non-contact laser doppler systems, length- and cross-section light scanners possibly supplemented by other 2D and 3D sensors that perform their work without interrupting the process, normally during regular transportation of the measurement objects, stable, user-independent and highly accurate. The dimensional control is used to detect incorrect parts, tolerance violation and for the documentation of the manufacturing or delivery quality status. Dimensional control systems from ELOVIS are used to measure profiles, seals, hoses, pipes made of a wide variety of materials.

Typical measurement objects:

  • Extrusion Profiles
  • Extrusion Moulding Profiles
  • Sealing Profiles
  • Hoses
  • Medical Tubes
  • Hydraulic Hoses
  • Plastic Pipes
  • Metal Pipes
  • Bolts, Ingots

Machines requiring a dimensional check:

  • Extrusion lines with guillotines and flying scissors
  • Extruded profile lines with and without sawing
  • Conveyor line after cross cutters, knives and punches
  • Continuous processing machines for edge processing, trimming, surface treatment, painting, …
