INSPECTION MARKINGS

Inspection markings ensure quality and identify the different product properties in relation to specified parameters.

Identifying and classifying the characteristics of a product is an integral part of quality control and an important component of quality assurance.

  • Tasks in manufacturing processes (monitoring, sorting)
  • Automotive industry (e.g. system check)
  • Plastics industry (e.g. leak tightness)
  • Steel tubes (e.g. welding seams)
  • Wood industry (e.g. wood quality)
  • And others. Ask us!

APPLICATION EXAMPLES INSPECTION MARKINGS

 

INSPECTION MARKINGS ON CABLE WITH PVC SHEATHING


CABLE MARKING AS ERROR MARKING

OK marking of cables.
Color marking for evaluation after electrical inspection. Visible recognition of the marking on smooth black PVC surfaces.

  • Marking color green (all primary colors can be supplied)
  • Short drying times
  • Elastic mark

INSPECTION MARKINGS ON COLORED SURFACES


OK MARKING OF VEHICLE CONNECTOR

Fluorescent marking / color marking for the visual and automatic recognition of "OK" markings on vehicle connectors. Highly visible even on black plastic surfaces.

  • Marking color yellow
  • Short drying times
  • Good visibility
 
 

OK MARKING ON COPPER ALLOY CUP SPRINGS


Marking for the visual and automatic recognition of "OK" markings on metal surface. Highly visible white marking on oily and black surfaces. Recognizable using a contrast sensor.

  • Marking color white
  • Short drying times
  • Automatic recognition

INSPECTION MARKINGS ON COLORED SURFACES


MARKINGS OF CLUTCH FRICTION LININGS

Identification markings of clutch plates.

Color marking for evaluation after inspection. Recognition of the marking on highly absorbent surfaces with slightly porous base.

  • Marking color red
  • Very short drying times
  • Reliable recognition

 

INSPECTION MARKINGS ON CIRCUIT BOARDS


INSPECTION MARKINGS ON SURFACES WITH PROTECTIVE COATING

Good/bad markings for visual/automatic quality assessments. Accurate application of dot marks, even in the circuit areas. Marking monitoring for "bad" markings. Good recognition even on surfaces with protective coating (IC circuit board) thanks to the fluorescent technology.

  • Marking color red
  • Short drying times
  • Reliable operation

MARKING OF CIRCUIT BOARDS


The circuit boards with one use are marked with a fluorescent orange marking color. The marks are only barely visible. An automation with color cameras/sensors in the daylight spectrum is not possible. Thus, only markings in the UV or IR range are suitable for optimum recognition on complex and fragmented structures and surfaces. The marking systems, marking fluids, and the matching sensors will be summed up and defined in a personalized project.

MSM marking application for circuit boards. The low visibility marks can be read out with a luminescence scanner (UV light excites the luminescence/fluorescence) of the LMT4 series to reliably check the inspection status or mark additional parameters. Consistent process management in the manufacturing process will lead to long-lasting profitably of the machines and production lines.
 
 

INSPECTION MARKINGS ON OILY SURFACES


GOOD/BAD MARKINGS FOR QUALITY CONTROL

Good/bad part or identification markings on metallic oily surfaces. Use of marking heads with marking monitoring and a marking distance of 20 mm. Adjustable marking dot size. Quickly drying marking paints. The reliable performance of the marking unit allows for its use in automated operations.

  • The marking fluids can be supplied in all primary colors
  • High visibility
  • Fluorescent markings possible

INSPECTION MARKINGS ON CONNECTING RODS


Inspection marking on oily connecting rods for exact positioning during assembly after "cracking".

  • The marking fluids can be supplied in all primary colors
  • High visibility
  • Good abrasion resistance
 
 

TESTING MARKINGS AFTER HARDNESS TESTING


OK markings of cam plates for automatic transmission. Fluorescence marking for the visual and automatic recognition of "OK" markings on a metal surface. Highly visible green marking on hardened, slightly oily surfaces. Recognizable with an optical sensor.

  • Marking color white
  • Short drying times
  • Automatic recognition

GEOMETRY INSPECTION MARKING STEEL SHAFT


OK marking of steel shafts for the automotive industry with a fluorescent marking for visual and automated recognition of "OK" markings on very dark metal surface. Highly visible green marking for identification at a later stage. Fail-proof marking system.

  • Fluorescence marking color green
  • Short drying times
  • Automatic recognition
