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.
