Compact and Laboratory―Scale Calendering Unit

―Introduction of“Lab Calender”―

Abstract

Sumet in Germany released its latest model of the Laboratory―scale calendering units. The compact Laboratory calender is a table―top design. The heated bottom roll is constructed from polished steel. The exchangeable top roll is constructed from steel, high―glossed polished, coated polyurethane, HNBR or composite as desired. An acrylic glass acts as a safety guard from injury. An integrated touch screen is used to set parameters and monitor the unit during calendaring. The sample is pulled through the rolls at a regulated speed and rolls―pressure is controlled. The advantage of this machine is flexibility because of the easily changeable rolls only taking in a few minutes. Short heat up time of the rolls is due to the small diameter, and constant temperature profile at the rollers is due to the special heating technology. The integrated sensor in the roller enables the control of the temperature in roll surface in high accuracy. This calendaring unit provides highly correlated results with the production machine and ensures the saving of time and costs of the testing.
