Keys and buttons

During the production of items designed for day and night use, labeling lasers assist in applying layers of lacquer to the three dimensionally formed surfaces of buttons and other control elements.

Due to the high quality demands of the consumer, the finished products must be inspected thoroughly for design faults.

The TOPAS test system from Intego GmbH offers automatic testing of the following fault categories:

• Variations in the exact positioning of pieces in the laser labeling unit
  Through positioning measurements and readjustment of the laser, faulty positioning of the piece during labeling is avoided, and the resulting yield is increased.

• Labeling defects resulting from the laser process
  Typical production faults, such as non-uniform line thickness, incomplete symbols, or permeability variations are detected.

• Surface faults from coating
  detection of lacquer faults, such as dirt inclusions, bubbles, or scratches.

• Luminance of the symbols
  Quantitative determination of the luminance Lmin/Lmax
