Pellet geometry and pellet uniformity both within a batch as well as between batches have a decisive effect on the feed behavior in an extruder. This must be kept in mind in particular when processing pellets on a laboratory scale, since the screws usually have shallow flights.
Collin® pelletizers are characterized by their high precision and reproducible pellets. The ability to adjust blade clearance precisely and observe processing easily are especially noteworthy features.

Testing extruders for thermoplastics Different process lengths and screw geometries guarantee a wide range of applications. Degassing zones, exchangeable grooved bushes, stroke adjustment systems, etc. allow extremely variable use in the design of extrusion lines. As standard, all extruders are equipped with a microprocessor control, which is located in a swivelling housing above the extruder. Available versions: Screw Ø in mm: 16/20/25/30/45 Process lengths in L/D ratio: 10 to 40 Measuring extruders COLLIN laboratory extruders can be equipped with further measuring devices in addition to the standard display of speed, current consumption and barrel temperatures, such as: * Melt pressure over the length of the cylinder * Melt temperature * Torque * Screw back pressure * Viscosity via rheometric slot die Comprehensive data acquisition and visualization systems allow the control of mono- and coextrusion lines. Rubber extruders For the processing of elastomers, rubber but also ceramic masses, extruders with modified design are supplied. Characteristic features are short process lengths, motor-driven feed rolls, special materials for screws and barrels. A modular system for the use of different process lengths enables the systematic development of elastomer compounds. Available versions: E Ø 30 x 12 D Type G E Ø 45 x 12 to 28 D Type G E Ø 40 x 10 D Type K
