Micro-Control Slot Die Coating Technology
Contactless Slot Die Coating
WebFlight slot die coating technology is a contactless method of applying coating solutions to web materials by modifying the micro-environment in which the coating solution and web meet. WebFlight slot die coating does not employ rollers, knives, blades, or other contact devices to apply or level coating solutions across the web. Instead, WebFlight slot die coating uses the following methods to optimize the slot die coating process:
Micro-Environment Control for Slot Die Coating
By precisely matching process variables, such as flow rate, line speed, and vacuum pressure with slot die coating fluid and web substrate properties such as viscosity, surface tension, and adhesiveness, WebFlight slot die coating systems enable maximum slot die coating productivity.
Fluid Isolation
By isolating the slot die coating fluid from the surrounding atmosphere, rheological characteristics remain constant throughout the slot die coating run, which means fewer adjustments of all other process variables. In addition, emissions of VOC's are minimized and easily vented.
Atmospheric Pressure Control
Reduction of the atmospheric pressure in the vacuum chamber creates a low-pressure fluid eddy on the upstream side of the injection point, which serves two purposes. First, it primes the web with slot die coating fluid ahead of the die slot, effectively enlarging the injection stream, thereby facilitating an integrated transition between adhesive and cohesive bonding. Second, it acts as an air dam, diverting residual boundary layer air away from the injection point and into the vacuum chamber.
Slot Die Coating Process Optimization
WebFlight slot die coating technology's precision controls facilitate extreme uniformity of fluid deposition, higher line speeds, less down time, less solvent usage and greater throughput for virtually any combination of web materials and coating fluids.
