VCML (Lab/Pilot Coater)

A versatile test coater with roll-to-roll processing. This machine is precision-designed to continuously perform printing, coating, and lamination on all kinds of flexible boards such as film, metal foil, and paper.Coating liquid such as solvent-based, water-based, and UV inks, coatings, varnishes, and adhesives can be printed and coated in various applications.Samples can be made with a very small amount of material.
VCML is used for product development, quality management, and small-scale production of special products.
* Equipment is set up for a demonstration in the Shin-Yokohama Showroom.

Demo Examples

Dry Laminate (PET/Aluminum Foil)

An adhesive was applied on 12-μm PET by gravure coating, and the solvent was volatilized with a dryer. After that, 9-μm aluminum foil was laminated.Samples were created by changing the speed from 10 m/min to 30 m/min.
