Extrusion International 1-2018

35 Extrusion International 1/2018 Dr. Collin GmbH Sportparkstr. 2, 85560 Ebersberg, Germany www.collin.de „Modularity in every single layer – our product philos- ophy is perfectly reflected in our new die. This die is used for the production of medical strands and cath- eter tubes. Moreover, the die is flexibly designed and customers can use it for the production of a wide vari- ety of blown films“, comments Dr. Kastner. „At the moment, the innovative, modular design al- lows up to nine layers. Strips can be integrated into any desired layer. It is possible to integrate two, four or eight strips with a width as required. Furthermore, the geometry of the strips can exactly be influenced.“ The Collin die is suitable for a variety of polymers and can be used as tube, strand or blown film die. Entrance Extruder – the entrance version for laboratory, R&D The E Entrance Extruder series is the cost-efficient ba- sic version, perfectly suitable for the first steps into extrusion. The lines are designed for laboratory opera- tion and R&D test series. Multi-inspection – allrounder for testing film quality The compact, robust and cost-efficient multi-inspec- tion of the product line Polytest Line is used for ana- lyzing different plastic materials and mixtures but also for the processing of virgin materials, compounds, masterbatches or for analyzing recycled materials. The modular design of the measuring system enables the adaptation of measuring methods to the correspond- ing customer requirements. Via three main modules, rheological melt characteriza- tion, optical film inspection and mechanical film test- ing are possible: • Real-time control of the melt viscosity by the MVR, iV-value or the apparent viscosity • Statistical error detection (gels, black spots, …) at the film • Color control at the film by CIE L*a*b system • Detection of foreign polymers by NIR-analysis • Detection of stress-strain-values by film traction test Via an upstream melt pump, the multi-inspection sys- tem is provided with a constant melt flow and the pres- sure necessary for the rheological characterization is built up. The compact design and the options to use the multi-inspection online directly at the extruder or offline in the laboratory are also convincing aspects. By the modular design, the multi-inspection unit en- ables an individual configuration of the line, however, there are still all options for retrofitting available for the customer. Collin Lab & Pilot Solutions With headquarters in the Bavarian city of Ebersberg, Collin develops intelligent pilot and laboratory lines in modular system for plastic processing companies as well as for research institutes. The owner-managed company has been in business for more than 40 years and, as premium provider, the company sets world- wide technical and qualitative standards. Collin solu- tions are used for the development and the production of plastic products, material analysis, test series up to pilot tests which allow a scale up to production scale. As part of the product lines Teach Line, Lab Line, Pilot Line, Medical Line and Polytest Line, Collin develops in- dividual solutions – platen presses, roll mills, calenders, extruders, compounders, mono or coextrusion lines, pressure filter tests, rheometers or optical inspection systems.
