In the past decade, slot die has become one of the most widely used coating methods in the world. While the majority of slot dies on the market require time-consuming bolt adjustments to obtain uniformity, the precision of the Yasui Seiki slot die is due to meticulous in-house machining, to the 1/1000th of a millimeter to guarantee coating accuracy. The accuracy of slot die coating depends on the precision of the entire coating machine, and Yasui Seiki’s dedication to achieving the highest quality coating possible is reflected in everything they make. At MIRWEC Coating, we only use Yasui Seiki coating machines and coating technologies to deliver the best possible coating solutions to the US market.

HIGHLIGHTS

  • No profile adjustment bolts
  • Machined to 1/1000th of a millimeter precision
  • Profile accuracy/ levelness tolerance: Maximum deviation of 2μm across the entire length of the slot die lip. (Based on the most recent slot die inspection report, the maximum deviation was indetectable, in other words, less than 1μm.)
  • Patented manifold and lip configuration for extremely uniform coating
  • Exceptional coating tolerance of +/- 2% (majority of the slot dies on the market can only offer +/- 5% tolerance)
  • The system may be used in “On Roll” or “Off Roll” mode to ensure a wide range of coating thicknesses

APPLICATION EXAMPLES

Yasui Seiki precision slot die is suitable for coating thicker layers with higher viscosity coating fluids. For example, slot die handles thin to thick layers of multilayer ceramic capacitors very well and it does an exceptional job coating lithium-ion battery electrodes (both anodes and cathodes) as well as adhesives such as PSA (pressure sensitive adhesives).

A few examples of slot die applications:

  • Multilayer Ceramic Capacitors (MLCC)
  • Li-ion battery electrodes
  • Polyimide coating for flexible printed circuit (FPC)
  • Flexible solar panels
  • Inkjet printer photoresist coating
  • Film casting (polyimide, urethane, epoxy, etc.)
  • Nanomedicine
