Slot Die Coating

• Selectable coating modes: continuous or intermittent
• Coating thickness is decided by slurry viscosity, feeding speed, and gap between slot die and substrate.
• Continuous coating thickness: 30-150 µm (single-side)
• Intermittent coating thickness: 30-100 µm (single-side)
• One skim is included on standard package. The coating width can be realized by various shims and shim is customized.
  
• Thickness control: coating gap regulated by servo motor with 1 µm resolution
• Max. Coating width & length: 260mm x 5000mm (single side coating)
• Precision: ≤ ± 2µm
• Attention: The final coating thickness is dependent on a wide rage of parameters such as slurry viscosity, solid particle sizes, solid content, shim thickness, foil rolling speed and slurry feeding rate. Therefore, we are not able to guarantee that the 1-micron level film is achievable for all kinds of slurries. For further discussion, please let us know your slurry specs and coating thickness requirement. 

Reverse Comma Blade (Transforming) Coating

• Continuous and intermittent mode are selectable from the touchscreen
• Continuous coating thickness: 30 – 150 µm, ±3µm (single-side). Depends on different slurry viscosity.
• Max. Coating Width & Length: 260mm x 5000mm, ±1mm (single-side)
• Slurry Feeder Volume: 0.7L
• Coating blade is adjusted by motor with resolution ± 1µm

Micro-Gravure Coating

•  Continuous coating thickness: 1-10µm (dried film), accuracy: ≤ ±1µm (5-10 µm, dried film); < 1 µm (<5µm, dried film)
• The coating thickness is dependent on the viscosity of slurries
• Max. Coating Width: 280mm

Coating Speed

• 0.1 – 2 m/min

Drying Oven

• Heating method: Dual-direction convection hot air (Top + Bottom)
• Max. Heating Temperature: 150 ˚C
• Heating uniformity: ± 5 ˚C
• Heating Length: 0.8 m, single unit
• Power Consumption: 4 KW

A single convection chamber is equipped for standard. For coating materials with different properties, multiple convection chambers can be customized upon request. Please contact MTI prior to purchase for customization options.

           

Winding

• Equipped with two ultrasonic EPC (Edge Position Control) mechanisms at the unwinding and winding sections.
• Automatic alignment with accuracy of ± 0.5mm
• Suitable for substrates with varying material properties

Reeling/Unreeling

•  Independent tension controls on reeling and unreeling: 0 – 60N, adjustable

Compressed Air

• 0.5 - 0.8 Mpa is required (Air compressor is not included, please click to order)
• Attention: If a gas cylinder is used instead of an air compressor, a two-stage pressure regulator must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. 

Compliance

• CE certified

Slurry Feeding Pump

• Normally slurry viscoity for doctor blade, reverse comma blade, and slot die is suggested in the range of 2000 - 6000 cps. For micro-gravure coating, the slurry viscosity chould be 50 - 2000 cps.
