Slide Dies are an excellent choice for multi-layer coating. This approach coats many layers on a single pass, allowing efficient creation of multi-layer web structures such as photographic film, magnetic tape, and advanced inkjet papers.

In slide coating, the fluid from the slot furthest away from the web becomes the topmost layer. As this fluid slides down the face of the die, additional coating layers flow in beneath the top layer. The coating from the slot closest to the web becomes the bottom layer

Slide dies yield outstanding coating results as part of a complete system including fluid delivery, a positioner, and a vacuum box. Slide dies are constructed of stainless steel, and are available in a complete range of coating widths.

Coating fluid is spread uniformly across the width of each die by a precision internal cavity.

Stainless steel or plastic shims are used to set actual coating width and slot gap. As an option, a fixed slot gap can be ground into the die.

Benefits

Liberty slot dies provide excellent coating uniformity and help minimize waste and emissions.

Slide coating is available as part of WetWare™ trials, which bring Liberty equipment and a CCR Application Engineer to your pilot or production line.
