Casting Film Machine

A laboratory calendering machine is an apparatus used in laboratory environments to process materials into thin sheets or films.

It functions on principles similar to industrial calendering machines but operates on a smaller scale, catering to research and development phases for generating experimental samples.

This equipment involves passing materials through multiple rollers, subjecting them to compression and elongation to achieve the desired thickness, width, and surface characteristics.

Laboratory calendering machines have versatile applications across various fields, allowing researchers to investigate material attributes, conduct small-scale production, and test novel processes.
