Most common problems

As a result of bad application of Primer or PU, problems take place of:

Water ingress
Wind Noise
Insufficient PU adhesion strength
The possibility of defect detection once the glass is inserted is zero

Issue Sources

  • Discontinuities in the PU bead created by missing material
  • Bubbles inside PU material
  • Hard particles or lumps
  • Problems in the PU dosing system and it´s barrel the vehicle

PU Joint Control Check

The second phase of product application begins with the PU application. The PU Pressure Control program, developed by Eines, verifies the absence of air bubbles in the applied product.

The PU Joint Control System is equipped with a device to detect gaps or a lack of PU in the most difficult areas to inspect by the pressure control program.

In other words, the PU bead joint is the “critical” point where the beginning and the end of the PU bead are joined during the PU dosing process. At the start-up of the dosing process, there is a continuous increase in the pressure beginning from its minimum level to its stable level and a subsequent decrease as the process approaches its end. The pressure is variable at these two steps and the pressure control program can not take into consideration these measurements.

Example of dynamic inspection

Detection in real time of defects

  • Primer path position
  • Primer width
  • Primer gaps
  • Overspray (when spraying)
