ASI’s SILICONE RELEASE COATING DRYER INCREASES WEB WIDTH AND LINE SPEED CAPABILITIES
ASI designed and manufactured the drying system for a Midwest-based manufacturer of silicone release liners. The customer’s current equipment was unable to meet their operational demands of wider web widths, larger roll diameters, and a greater variety of substrates. In this new line, immediately downstream of the coater module is a 45’-0” long Advanced Systems, Inc. [ASI] two zone flotation drying system powered by natural gas. The dryer has the capability to heat the web up to 450oF to properly cure the applied coatings. The unique attributes of the flotation drying technology keep the web drying profile very efficient and the paper curl to a minimum. https://www.mwes.com/recent-projects-2/silicone-coating-line-system/. The drive and control system consists of Allen Bradley AC vector drives and a Safety PLC system that monitors all machine functions and the interlocked guard and operator safety systems.
This new line and drying system have greatly increased the manufacturing capabilities of the customer, including increasing the maximum web width from 36” to 65” and more than doubling the maximum web speed from 400 fpm to 1000 fpm. “The drying capability of the new flotation system also is more sophisticated with a faster and more effective heat transfer process.” Id.
ASI’s silicone coating dryer incorporates a specially designed plenum that minimizes silicate dusting in the supply air stream. This feature greatly reduces cleaning downtime and improves product quality by significantly reducing product contamination.
