Online Analysis AT-LINE STATION Extrusion Testing Platform real-time compliant material characterization Multifunctional • Melt index / Viscosity • Optical film inspection • Haze, Gloss • Film thickness • Continuous measurement of the extrusion process • Die swell measurement, melt tension

The Concept The At-Line Rheometer makes it possible to have continuous control of the polymerization process of pellets, fine granules or powder. Key rheological process information is generated continuously for possible close loop process automation based on the rheological characterization of material. This concept line consists of a combination of Online Rheometer, such as the MBR, SSR or RTR/RTS-TD and our EXTRUSIOMETER, that generates the melt. An optional raw-material feeding system (Online Sampler) ensures consistent material flow to the measurement apparatus to support the...

The Concept Lab-Extruder GOETTFERT Lab-Extruders are stand-alone measurement instruments that is why we call them EXTRUSIOMETER! More than a half century of experience and continuous development with rheological analysis are incorporated in our line of extruders and rheological testing equipment. Different standard sizes are available, as well as user specified cylinder systems. The EXTRUSIOMETER may be equipped with multiple pressure transducers and temperature sensors, just one of the many important characteristics of the device. The liquid cooling system avoids the plastification of the...

Film Analysis „Reflections“ on Rheology - transparent or maybe not... The continuous measurement of film thickness, gloss and detection of spots Film Thickness The laser distance measurement head operates with high precision, covering all the adjustable range. Its set-up can be optimized to cover a wide range of materials and surfaces. A simple Good/Bad analysis is available, also advanced functions, such as statistical analysis with averaging, min/max values and excentricity. Film Gloss Via the multi-angle gloss measurement, we cover the range from dull to high gloss. Using intelligent...

The Blown Film Unit AT-LINE Station - Downstream system options The Blown Film Station is a compact unit to blow, cool, draw-out and to wind up the extruded tubes. Primarily used in production quality control to measure how well the dispersion works in batches run on extruders and kneaders; in incoming quality control for color and spot distribution; in the development to find and control the max. draw-out of the polymer and to test the suitability of polymers and compounds used. Alternatively to produce small film tubes in different thicknesses, for applications mainly found in the...

Material Feeding - Online Sampler Pellets, fine granules, powder, ... - steady from A to B! To ensure fully automated measurements of the AT-LINE STATION, the system can be designed by feeding out of a silo or hooked directly to the production. In both application cases a sample is taken by the Sending Unit and transferred by a carrier inert gas (e.g. nitrogen) to the Receiving Unit. Amplifier stations are available to make sure no material is stuck, if distances become too large. During the startup an optimization at site it is made sure that it runs perfectly year in, year out. Many soft-...
