Defect Detection PET Preformer System

Listing ID #3363386

PREFORMER system has been designed with the aim to control the quality of the PET preforms by detecting their defects. These typical defects may be originated by improper injection moulding, improper preform handling or off-speccontaminated PET chips fed into the injection moulding machine. The design of this system is the result of more than 20 years of operational experience in injection moulding of PET preforms for the world market. Preformer sorts out with extreme precision + reliability the PET off-spec preforms by the computer vision (5 CCD cameras) and the vacuum technology (mechanical test)
Defects: oval shape, lack of material, lack of tightness of the sealing ring, incorrect geometrical dimensions, deformation, long injection point, micro-holes in the injection point, burnt rings, moisture rings, unmelts, crystalline (haze), foreign particles, black specs, bubbles, chromatic variations, streaks, etc.
