Automatic Film Coaters: Even Films for Membrane and Battery Laboratories

7 hours ago

2 min read

At a glance. Membrane and battery researchers cast films every day, and small differences in thickness change the results. The Tech Inc. Automatic Film Coater with Heated Vacuum Bed draws an applicator across the substrate at a set speed, holds the substrate flat by vacuum, and dries the film in place. It is one of the best tools a membrane or battery laboratory can add.

How it works

The vacuum bed holds glass plates, films and metal foils flat.
A motorised carriage pushes the film applicator at a constant speed.
A micrometer applicator sets the wet film thickness.
The heated bed and drying cover dry the film without moving it.

Versions

Version	Use
Standard coater	Vacuum bed, heater and motorised applicator
With drying cover	Heated cover for drying in place
Wide-bed version	Wider membranes and electrodes
Glove box version	Compact frame for use inside a glove box

Why it is one of the best things to happen to film research

Repeatable films. Constant speed and gap give the same thickness every time.
Flat substrates. No wrinkles in foils, no lifted edges on glass.
Dry in place. The film is not disturbed between coating and drying.
Two fields, one machine. Flat sheet membranes and battery electrodes on the same coater.

Where it is used

Membrane research and teaching laboratories, battery electrode and separator research, coating development, and pilot lines that need small samples before roll casting. For longer films, see our roll casting machine with slot die and lab casting machine with heating.
