The work flow of the coating machine equipment

Before coating, load the clean and stretched screen from the front of the coating machine, and some models can also load the screen from the side. Among the models designed for large-format screen frames, side loading is more common, because the screen frame is large and bulky, and side loading can reduce the amount of lifting and moving. When the automatic screen coater is running in-line with other automatic screen processing equipment such as cleaning equipment, regeneration equipment, drying units and developers, it is more convenient to load plates from the side.

Regardless of how the screen is loaded, once the screen is in the correct position, the pneumatic or mechanical clamping device closes and locks the screen. For more convenient operation, many models have foot pedals to control the action of the plate clamp, and the operator can free both hands to control the screen plate. After installing the screen, pour the corresponding photosensitive emulsion into the automatic coating machine, and then start coating. According to the functions of the control system and the equipment, the equipment can coat both sides of the wire mesh at the same time.

There are two coating methods, one is to coat the photosensitive emulsion on the screen by multiple wet pressing operations; or the drying process is added after each coating. A machine that quantitatively coats liquid (or melt) polymer materials such as adhesives or coatings on the surface of materials.

It is suitable for the production of soft substrates such as PVC/PE film.

Simply put, the glue is applied to the film. Specifically, it includes gluing, drying, winding and tension control.

The film can be PVC, PE, PET... or some paper, such as hot melt adhesive on the release paper.
