What Is Calandrando?
Calandrando, originating from the Italian word “calandrare” meaning to roll or press, represents a sophisticated process employed across industries for the purpose of shaping materials such as textiles, plastics, and paper.
This method entails guiding materials through a series of precisely engineered rollers, subjecting them to controlled pressure and temperature variations to achieve desired outcomes like thickness adjustment, surface smoothening, or texture alteration. Initially rooted in the textile sector, calandrando has evolved over centuries to find extensive utility in various other sectors, thanks to its adaptability and effectiveness.

Historical Overview
The evolution of calandrando can be traced back to the onset of the Industrial Revolution, a period characterized by mechanization and automation. Initially devised for refining textiles, the process gradually expanded its horizons to encompass a broader spectrum of materials and applications. With time, technological advancements refined the calandrando process, enhancing its precision, efficiency, and versatility, consequently broadening its scope across diverse industries.
Principles of Calandrando
Compression and Controlled Pressure Manipulation:
Calandrando relies on the application of controlled pressure to alter the properties of materials. Through compression, materials are reshaped and refined to achieve desired characteristics.
Roller Configuration and Functionality:
Materials are fed between a series of rollers configured in the calandrando system. These rollers play a pivotal role in exerting pressure and shaping the material. They can be heated or cooled to further influence material behavior.
Temperature Regulation:
The temperature of the rollers is a critical parameter in the calandrando process. Heating or cooling the rollers can soften or harden the material, respectively, facilitating desired modifications such as thickness reduction or surface smoothening.
