At the NPE, in the medical sector, Collin showed a Medical Line line with the Extruder E 12 x 25 D, a strand die 1 x 2 mm, a medical belt take-off and a strand pelletizer. The advantage of the Medical Line E Extruder is that our customers can produce small batches ", says DI Dr. Friedrich Kastner , CEO and Managing Partner Collin. „That is useful for small batch production, product tests and test series."

Besides the excellent process control, extrusion is possible at very low temperatures – especially for certain medical additives, this is essential. The Collin Medical Line lines are characterized by high accuracy, cGMP/FDA validated production, GAMP5 validation and excellent and quick cleaning and are manufactured according to customer requirements.

At the NPE booth, Collin showed the new blown film line, which has completely been updated. Via the Collin bubble control, the technically and optically optimized machines produce perfect blown films.

„Amongst others, the take-off unit plus lay flat unit and the winder with manifoldly adjustable winding parameters have been improved. Thus, also with different materials, optimal winding quality can be achieved. Furthermore, it is an advantage for our customers that, depending on the application, they can flexibly choose between contact, central or central winding with gap. By means of an exact web tension measurement combined with a winding PC and modern drives, we achieve a very good quality", explains Kastner. These bobbins can also easily be further processed on production lines ", says Corné Verstraten, CSO Collin.

„Moreover, the standard speed has been increased from 30 m/min to 50 m/min. If desired, the speed can be higher – for example in order to approach production speed if required", explains Verstraten. The quality of the film can permanently be controlled via the COFIS film inspection system.

At the booth of NGR Next Generation Recycling GmbH, Collin presented the compact, robust and cost-efficient multi-inspection including COFIS film inspection of the product line Polytest. The all-round quality control multi-inspection is used for analysing different plastics and mixtures but also for treating virgin material, compounds, masterbatches or analysing recycled plastic material. The modular design of the measuring system allows to adapt the measuring methods to the respective customer requirements.

The test system COFIS is used for inline detection of optical detects in running flat or blown films. The high-quality line allows a definition of up to 10 defect classes by means of up to 14 defect criteria.
