PVA Introduces Continuous Film Calibration
PVA first unveiled their patent pending Continuous Film Calibration option for selective coating applications in Las Vegas, NV on March 15, 2016.
Continuous Film Calibration will uniquely sense the entire coating pattern. Unlike pre-existing technology that moves across a sensor seeking the film edges to determine pattern width, Continuous Film Calibration will quickly detect the entire film and feedback not only pattern width but also any gaps or breaks in the film itself down to the pixel level. "Just as you shouldn't judge a book by its cover, you shouldn't evaluate a film pattern simply by the edges", says Frank Hart, PVA Sales and Marketing Manager. "We feel Continuous Film Calibration provides PVA customers the next level of process control that they seek in high reliability applications."
Users can easily set the desired pattern width in PVA's proprietary user interface. Any variation in the width during a routine verification will result in automatic recalibration of the fluid delivery system settings with no required operator intervention. Since the pattern is evaluated in its entirety and does not traverse over a stationary sensor to recalibrate, the duration of time and the volume of coating required to recover to the optimal pattern characteristics are significantly reduced. Subsequently, Continuous Film Calibration results in the most comprehensive pattern check and correction tool on the market assuring reliable, worry-free processing of control coating materials.
