LayerWatcher

The system simplifies the inspection of barrier layers in PET preforms. In a non-destructive inspection process, the system fully inspects the barrier material.

Your non-destructive preform layer inspection

Stop cutting and delaminating your preforms for the quality control of your barrier layer. The LayerWatcher has been developed to inspect preform layers in an objective, quick, and non-destructive way. Its game-changing measuring technology provides an indispensible tool for your quality inspection.

The preforms are given into the system as a shot and are identified by their cavity numbers. In about 45 seconds, the LayerWatcher inspects up to 100.000 measuring points. Afterwards, the results allow for different visualizations – whether it is a visualization of individual layers, or a comprehensive 3D overall image of the preform. Thanks to the prompt, detailed feedback, you optimize your production process faster and reduce the production of rejects. In addition, you will receive the results summarized in exportable quality reports with all important information about the barrier layers.

Innovative measuring technology

The LayerWatcher is able to measure all layers of the entire preform thanks to its revolutionary OptoSonix scan technology. It identifies the layers by their different optical characteristics.

The measuring results are an accumulation of thousands of point positions within the preform layers. These positions have a minimum grid step of 0.2 mm and thus create a dense mesh that indicates the layer thickness.

In a second step, the data is processed and compressed into a few clear parameters defining the characteristics of the layers. According to these results, the user can re-adjust the production process and define limits.

FAQs about the LayerWatcher

The inspection speed is 45 seconds per preform. The measured data is immediately displayed on the screen.
The system is designed to inspect preforms of PET (polyethylene tereph-thalate), either monolayer (PET throughout the wall) or multi-layer with external (skin) layers of PET, making up outer and inner dimensions of the preform and one middle layer (core or barrier) of a barrier material. PET may be any of the commercially available grades, high or low IV, homopolymer or copolymer.
A set of preforms is placed in the included bunker. The preforms are then transported, oriented and fed into a pocket wheel where each preform is automatically identified by its cavity number. Afterwards, a mechanical handling grabs each single preform and leads it to the measuring head where the inspection is carried out. The software processes the gathered image data and saves the measurement results for each preform. The inspected preform is then ejected into the good part or bad part box, depending on the inspection result.
