Slit Coating Method
Possibility to coat the whole surface pattern by changing the length of the slit die
Curved Surface – SC07 Type
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
Curved Free-Form
Coating width variable slit coater
- Automatically product type change over
- Free-formed Coating
Coating width variable mechanism
- Possible to continuously vary coating width in operation
- Structure to prevent resin leakage
- Gap switching is possible with shim
Coating a curved surface is possible
- Coating on Concave and/or Convex surface
- Control to make the die perpendicular to the coated surface
Multi-Device
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
Slit Coater – SC02
Features
- Designed to coat the resin to the glass substrate by slit process
- The loading and unloading of workpieces are done by operator
