Yasuiseiki’s special features
Slot Die Coating
Slot die is one of the famous coating methods. It has stability and sealability, and it is suitable for high speed coating.
Yasuiseiki’s slot die has original lip form and high accuracy. Our slot die can coat not only thick thickness but also thin thickness ( thin thickness coating depends on your solution). You can choose from 2 types of lip form, standard or thin model.
Accuracy and Quality Check
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 we make.
Thanks to our extremely high precision machining and rigorous quality testing, Yasui Seiki precision thin lip slot die can now deposit as low as 1 μm wet.
Workmanship of Yasui Seiki Precision Slot Die
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
Application Examples
Yasui Seiki precision slot die is very useful when a coating method other than MICROGRAVURE™ is necessary. 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.
Highlights
- No profile adjustment bolts
- Machined to 1/1000th of a millimeter
- Patented manifold and lip configuration for extremely uniform coating
- Coating tolerance is +/- 2%
- 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 very useful when a coating method other than MICROGRAVURE™ is necessary. 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.
- 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
