MSK-AFA-EC350 Lab Scale Roll-to-Roll Flat Tape Casting System with 350mm Width and Integrated Convection Drying Heater
The MSK-AFA-EC350 is engineered for laboratory-scale production of flat tapes and films using a roll-to-roll process. It is ideal for coating applications requiring precise control over film thickness and uniformity, such as fuel cell membranes, battery electrodes, and biological films. This system enables continuous coating on substrates up to 400 mm wide, with a maximum coating width of 350 mm, facilitating efficient material development and testing.
The system integrates a convection drying heater with a 3-meter length and aluminum alloy heating bed capable of reaching temperatures up to 100°C, controlled digitally with ±1°C accuracy. An electrostatic dust removal unit ensures a particle-free coating environment, critical for high-quality film production. The coating process uses a doctor blade on a flat plate, with substrate unwinding, blade coating, bottom heating, drying, and rewinding steps. Optional slot-die and ultrasonic spray heads are available to expand coating capabilities.
