Slit Coating
Slit Coating Method
Possibility to coat the whole surface pattern by changing the length of the slit die
Under development
Curved Surface - SC07 Type
Slit coats on concave and/or convex and flexible surfaces as well as flat
Features
- Stage conveys a part and slit die rotates to angle according to part’s shape
Optimized slit die
- Design for maintenance
- Optimal degasing design
- Suitable for high viscosity resin
- Resin leakage prevention structure
- Optimal inner pressure design
- Optimal lip design
- Gap adjustment mechanism

Improvement of productivity
- Reducing the preparation time to change the coating width, high-mix low-volume production is enabled
- The changeable nozzles can digitally set the coating width with its unique nozzle structure. This greatly contributes to improving the productivity and the use efficiency of material
Improvement of use efficiency of material
- When changing the coating width, disassembly and cleaning are not required; besides material loss is reduced
