Agr introduces novel solution for non-contact thickness measurement of non-PET containers

Agr International has introduced a novel, breakthrough method to measure thickness distribution in HDPE, PP, PE and similar containers. With this method, an entire segment of containers is now able to be measured for thickness distribution with light-based technology. Prior to this development, many HDPE, PP, PE and similar containers that were highly coloured and had limited transparency, were not able to be measured using non-contact, light-based measurement techniques.

In the development of its new Gawis 4D dimensional and thickness measurement system, Agr engineers were challenged to include the ability to measure thickness on a broader range of bottles including those constructed of HDPE and non-PET materials. To address this, a novel “Integrated Method for Thickness Measurement” was developed and implemented into this system.  This patent pending method incorporates a proprietary programmable spectrometer and utilizes the integrated- method to analyse the signal level of multiple absorption bands within the entire NIR band width.  Using this new technique, bottles that are highly coloured and have a transparency to IR light as low as 5% can now be measured for thickness.

Agr’s Gawis 4D is the latest offering in a long line of automated laboratory measurement systems for plastic bottles and containers.  The Gawis 4D is designed to provide highly accurate and repeatable  dimensional gauging as well as high precision, non-contact thickness measurement over the entire bottle or preform, with a throughput of less than twenty seconds per sample. In addition to the Integrated Method for Thickness measurement, this system offers a number of key features designed for simple and fast operation. These include Agr’s patent pending AutoJob automated job setup for dimensional measurements, a library of standard industry finish templates, easy-to-operate multi-function touch and go UI, Industry 4.0 compatibility and a wealth of data transfer methods.

Agr manufactures a complete line of products for the measurement and testing of plastic containers.  Agr products are designed to assist container producers, converters and fillers stay competitive, while meeting the increased quality demands of today’s changing world.  Additional details can be found on the Agr website at www.agrintl.com.
