Quality Control and Inspection in Blowing Process

    AgrTopWave's PETWall plus Vision is a system for quality control of the outer wall thickness of PET containers based on an accurate camera inspection system. The outer wall thickness sensor designs four measurement zones for each vessel. Of course, the user can adjust the position. The system uses infrared absorption technology to measure changes in the area being examined, while the camera performs random tests on other, more critical areas such as the bottom of the bottle and the seal. The main content of the test includes whether there are pores, impurities, dark spots, etc., because these will affect the integrity of the container. Convex, concave, nicks, stains, etc. will affect the regularity of the surface of the container.

Introducing this system in the blowing process has many benefits. The biggest advantage is that each bottle can be accurately detected even under high-speed conditions. Through the problem information reported by the system, it is possible to find out exactly where it appears, thus ensuring the normal operation of the production line.
