Products

Measuring in different dimensions
Strips, sheets, plates and blanks

Rolled products such as strips, heavy plates, sheets or plates made of steel, aluminum or non-ferrous metals can be 100% inspected in-line the production cycle using our laser measuring systems; no need to take the products off the production line. In addition to metals, certain plastics or plastic plates can also be measured.

Precise and fast laser measurement

  • Thickness measurement: Accuracy starting from ±1.5 μm at speeds of up to 2000 m/min
  • Flatness and contour measurement: Accuracies - Flatness starting from ±0.05 mm / Width from ±0.15 mm and Length from ±0.1 mm, all at scanning speeds of 0.5 m/s

 

Automotive glass, up to 450 °C

For windshields, roof glass, rear, and side windows, surface curvature can be measured immediately after the bending process. Early and comprehensive inspection during production allows automotive suppliers to identify and remove defective parts before further processing.

Fast and heat-resistant laser measurement

  • Cycle time: < 8 seconds from glass to glass

 

Forged specimen, up to 1,200 °C

3D features of test parts can be measured immediately after the forming process, with prompt prediction of the cold dimensions. Component inspection is done directly on the production line, enabling an early adjustment of the forging process and preventing defective scrap material.

Fast transition from hot to cold: 3D contour laser measurement

  • Capture 3D features in just a few seconds
  • Cold dimension prediction with an accuracy starting from ±25 μm

 

Why are our laser measurement systems so precise?
  • For over 30 years, nokra has been developing and manufacturing systems and laser sensors. Each sensor is calibrated in the lab for specific applications before installation.
  • The system software incorporates specially programmed algorithms to evaluate measurement data and enable feedback of digital values into the production process.
  • The laser measurement systems are MSA-capable and designed for use in production environments to meet quality standards and regulations.
