Inspecting Large Coated Profile and Tubes
Surface and Shape Checked at the Same Time
Pixargus GmbH in Würselen, Germany, presents the new inspection system ProfilControl 7 DualVision XXL, which is able to inspect also edged and crooked large profiles.
The manufacturer says that, in addition to plastics, the system can be applied to test materials such as rubber and metal. This is due to new camera technology and calibration technique, which works electronically, requiring no mechanical actuation. As a result, inspection can be much cheaper now. The system is designed for diameters up to 260 mm, or even larger, if required.
One example of application for the new technique is the inspection of large profiles at the site of a global leader in PVC window profiles with customizable color application, i.e. with the respective wide range of color variation. The products are coated with decorative, brilliant colors. At the same time, the PC7 DualVision XXL system inspects the quality of application. According to manufacturer information, the new system can even detect the slightest color errors, requiring no expensive color cameras. Not even the strong reflections of the brilliant colors are a problem, says the company, which is a specialist in measuring technology.
The system uses a label printer to mark errors in the profiles. These profile can then be sorted out automatically, or manually on the inspection table.
