Imperfections in empty PET containers, either returnable or straight from the molder, can result in damaged or wasted product.
Outer sidewall refers to the outside surface of a container, usually below the thread and above the base. This outer surface can often become visibly scuffed or chipped, especially in REFPET, sometimes so badly these damages may result in leaks.
Twelve images are captured at 30 degree intervals while the bottles rotate past the inspection window, providing the most thorough inspection and fewest number of false rejects.
Bottles rotate against each other as they pass through the inspection field, allowing for 360 degree detection.
Adjustable LED strobe allows for the illumination of bottle features for easy flaw detection.
The base of a bottle receives the most amount of wear during the container's life, and easily sustains scuffing or chips. Thorough inspection of both the inside and outside of an empty container's base prevents flawed packaging and contaminated product from reaching the market.
The bottle's inner sidewall includes all the inside surfaces of the container from the base up through the neck. Damages on these surfaces can be difficult to see, but can easily grow mold or develop cracks after the container has been filled.
A bottle's thread is the molding at the top of the neck where the cap is screwed in place. Damaged thread can prevent the container from sealing properly, threatening pressurized or perishable product.
Without additional inspection, leftover caustic can occasionally remain inside of REFPET containers and contaminate the final product. FILTEC uses both radio frequency and infrared detection technologies to inspect REFPET containers for residual caustic.
Detects smallest amounts of caustic, even once it has dried.
Detects oil, paint, gasoline, and other liquids and objects with low conductivity.
