Precision coating encompasses sophisticated, highly controlled functions, including distribution of liquid across a conveying web and control of coating thickness in the down-web direction. Uniform coatings require precise fluid metering, precision coating heads, and tight conveyance speed and tension controls. Thus, an operation’s capabilities are partially defined by the quality and accuracy of solution delivery systems—how the fluid gets to the coating method.

This article series will detail the requirements for advanced solution delivery and provide advice for ensuring optimum product quality and cost control. Each of these goals is satisfied with an operationally sound process that ensures technical efficiency. From pressurizing the solution and purging the system through to mixing and recycling the solution, the steps must be clear and well established.

In Part 1, we will focus on the pre-work and approach to design or adapting a solution delivery system. Part 2 will then cover how to optimize the performance of the system to improve product quality and yield.
