The quality of a clear sheet is defined by the calender unit . For this reason, particular attention must be paid to the chromium plated and high-mirror polished solid calender rolls. These represent the quality for producing sheets with perfect surfaces. .
The calender is a series of hard pressure rollers used to finish or smooth a sheet of plastic materials.
These rollers are designed on vertical direction for PP, PS, PET however, for PET sheet only, rolls design as horizontal direction to reach high thicknesses while keeping homogeneity.
Kuzey calender units provide high precision concentricity and flexural strength, even the thinnest of sheets can be manufactured with extreme accuracy. Each Roll is controlled with a separate thermo-regulators. Thermo-regulators can be adjusted separately from 10 – 90° C. Calender Thickness Motion control is by the servo and gearbox system.
