Precision rolls are used to control the coating thickness and uniformity in a coating operation. Industrial customers depend on MECA Solutions to deliver exceptionally tight tolerance rolls for a wide range of applications.
Coater rolls and roll coating machines apply liquids such as adhesives, oils and varnishes to a variety of substrates. The coater rolls must be straight and concentric for uniform distribution of the coating liquid. Anything less than precise results in lost time and money, and a suboptimal final product.
“We manufacture coater rolls, carbon fiber rolls and other rolls to extremely tight tolerances,” says Tim Olson, sales manager at MECA. “Our customers know they can depend on us for rolls that maximize their production capabilities and provide the highest quality products.”
3 ways coater rolls control application thickness
Coater rolls are used in a variety of configurations to transfer a layer of coating from the surface of a roller to a substrate or part. The amount of liquid that sticks to the substrate is dependent upon the coating process, the substrate and the surface characteristics of the coater roll. Here is a brief description of three common ways of controlling the coating thickness:
Metering roller – The coating thickness is controlled by adjusting the gap between the coating roll and the pickup roll or the metering roll.
Metering blade – Rather than adjusting the amount of liquid application with another roll, this technique relies on a blade to adjust the gap between it and the coater roll. The excess liquid caught by the blade flows back into the tank.
Transfer rolls sytem – Transfer roll systems are similar to metering roll systems, using a series of precision rolls with various covers or features such as heat transfer capabilities.
MECA can work with your existing coating machine and process to develop efficient coater rolls for a variety of adhesives and other liquids.
