Targeting Zero Overlooked Defects with 360° Inspection

Even metal components requiring visual inspection of their entire surface can be processed in 5 seconds. Defects with a depth of 0.3 mm are accurately detected.

Automated visual inspection system for casting/forging components Lulimo H

  • Our proprietary multi-angle multi shot system enables complete inspection for microscopic defects in a cycle time of just 5 seconds with zero overlooked defects.
  • An integrated transfer system allows continuous high-speed processing of components from loading to inspection and finally unloading.
  • Shot blasting marks are removed by our proprietary image processing, enabling the detection of hidden defects.

Examples of targeted defects

Detection of defects with a depth of 0.3 mm or more

Issues including ironing marks, scrubbing marks, dents, pits, underfills, die-related defects and surface roughness/unevenness with a depth of 0.3 mm or more can all be detected at high speed.
Detection at a depth of just 0.1 mm is possible depending on component conditions. Please contact us for more information.

Underfill / Scale / Surface unevenness

Connecting rod / Yoke / Carrier / Dent Targeted defects: Dents, scratches, surface unevenness, underfills, overfills, galling, burrs

Automated visual inspection system for casting/forging components
Overview of Lulimo H

Inspection workflow

All inspection processes are performed automatically inside the system.

STEP1 Registration of master images

Master images of approved components can be created in just a few minutes. Comparison with these masters enables even components with large tolerances to be inspected with great accuracy.

STEP2 Loading

We are able to design automatic loaders that can handle a wide range of components as optional units.

STEP3 Surface inspection

Components loaded into the system are automatically transferred to the first inspection unit. This unit is equipped with 17 cameras that are used to capture images for inspection. The images are then compared with the masters using our proprietary image processing technologies, enabling the detection of defects.

STEP4 Reversal

Once image capturing is completed for components in the inspection unit, their front and rear surfaces are reversed. They are then transferred to the second inspection unit.

STEP5 Rear inspection

Images of the rear surfaces are captured in an inspection unit similar to that used in step 3. These images are also compared to the masters.

STEP6 Separation and
unloading

Once inspection is completed, accepted and rejected components are finalized and sent to their respective unloaders for discharge.
