Pharmaceutical Extruders  Manufacturers, Traders, Suppliers

COLLIN ® single-screw extruders are characterized by their rugged construction as well as up-to-date and precise control of temperature and drive. The user-friendly control system saves all essential process parameters, making them accessible for several types of evaluations. The large number of screw diameters available (16 mm, 20 mm, 25mm, 30 mm, 45 mm, 60mm) in conjunction with the variety of different screw geometries offered allows you to choose from economical machines for a wide range of applications. Standard screw length is 25D. Starting at a screw diameter of 30 mm, barrier screws up to 40D in length are available. Screw geometries can be modified by incorporating various screw-on shear and mixing sections. Every machine features its own control panel, permitting integration into a line or use as a stand-alone unit.

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
