“For this new line, we have developed a variety of innovations. Our aim was to clearly show and develop our competence in this field”, says DI Dr. Friedrich Kastner, CEO Collin.

During the K, Collin shows the innovation multi-inspection, the automatic pressure filter test with autosampler, the online viscometer and the COFIS film inspection:

Innovation Multi-Inspection – absolutely new on the world market
„The innovation multi-inspection of our product line Polytest Line is used for analysing different plastics and mixtures but also for the processing of virgin materials, compounds, masterbatches or the analysis of recycled plastics material. Our aim was to develop and manufacture a compact, robust and cost-efficient online measuring device. The modular design of the measuring system allows the adaptation of the measuring methods to the corresponding requirements of our customers”, explains Kastner.

The Collin multi-inspection system generally includes three main modules – a rheological melt characterization, an optical film inspection and a mechanical film test:
• Real-time control of the melt viscosity with the MVR, iV-value or the apparent viscosity
• Statistic error detection (gels, black spots, …) on the film
• Colour monitoring on the film by CIE L*a*b system
• Detection of foreign polymers by NIR-analysis
• Determination of stress-strain-values during a film traction test

Via an upstream melt pump, the multi-inspection system is provided with a constant melt flow and the pressure required for the rheological characterization is generated. The compact design and the options are also convincing, since the multi-inspection can be used online directly at the extruder or offline in the laboratory. The modular design of the multi-inspection unit allows an individual configuration of the line, however, all options of retrofitting are still available for the customer.

Automatic Pressure Filter Test with Autosampler – unique on the world market
With the automatic pressure filter test with autosampler, quality differences in a polymer caused by agglomerates, insufficiently dispersed fillers resp. contaminations can be detected – fully automatic.

“With the unique automatic material and screen changing system, at the moment, the pressure filter test can successively process 7 material samples – without system stop. Beneficial to our customers is that, with our line, downtimes and personnel costs are considerably reduced and high reproducibility is provided”, says Corné Verstraten, CSO Collin.

Online Viscometer – testing system for inline-detection of optical defects on films
The Collin online-viscometer is used for continuous monitoring of the melt viscosity at a production extruder. Two melt pumps with only one drive ensure the continuous monitoring of the melt. Due to its compact design, the Collin Polytest Line measuring device is characterized by a high degree of automation, flexibility and a closed material cycle.
COFIS Collin Film Inspection System – high-quality testing line for error detection
The Collin Film Inspection System COFIS is a high-quality testing line, which allows a definition of up to 10 error classes by means of up to 14 error criteria. The line detects optical errors in a running flat or blown film. Between the cooling and take-off rolls, a LED light source as well as a line camera are installed. Thus, defects in the film, which have not been dispersed, can be detected and evaluated.

Furthermore, the Collin Polytest Line includes the following measuring devices: Bypass Online-Rheometer WROR & MOR, manual pressure filter test, automated pressure filter test and the COFICOS-system. Moreover, customers have the possibility to use one of the Collin test laboratories (in Germany and Norcross/USA) for testing purposes.
