Micro Gravure Coating

Application

This allows for an exceptionally stable coating that is thin and uniform. A reverse micro gravure coating can be applied for a even smoother coating surface when compared to the direct micro gravure coating.

Features

Suitable for application that is critical for thin, uniform and glossy coatings.

Reference range of application

  • Viscosity: <1,000 cp
  • Wet thickness: <30μm

Slot Die Coating

Application

Suitable for the widest range of viscosity level requirement and coating thickness requirement. Slot die coating is for those that are looking for an ultra-precision and uniformity control.

Features

  • Wide coating range.
  • High precision.
  • High cost for job change-over.

Reference range of application

  • Viscosity: <10,000 cp
  • Wet thickness: 10 μm~200 μm

Direct Gravure Coating

Application

For low to middle viscosity level and is suitable for thin and high speed coating applications. Smoothing bar can be added to improve coating surface.

Features

Reliable, stable , economic,

Ability for pattern coating, registered coating.

Reference range of application

  • Viscosity: < 500 cp
  • Wet thickness: < 35 μm
proimages/technology/Reverse_Gravure_Coating2.png

Reverse Gravure Coating

Application

Ideal for low- to medium-viscosity coatings, offering operational advantages for non-Newtonian fluids—particularly shear-thinning formulations and slurries. Coating weight can be adjusted by varying the relative speed differential between the roller and the web.

Features

  • Reverse-direction coating: Utilizing shear forces to refine surface quality.
  • Enables fine-tuning of the applied coating volume.
  • Demands precise gap control between rollers.

Reference range of application

  • Viscosity: < 1,000 cp
  • Wet thickness: < 35 μm

Gravure Offset Coating

Application

For application that requires more control and flexibility over the coating thickness and weight. 

Features

  • Reliable, stable, flexible.
  • Suitable for thinner thickness coating requirement.
  • Gap control can be added to enable Reverse-direction coating for diverse coating mode.

Reference range of application

  • Viscosity: 100~1,500 cp
  • Wet thickness: < 20 μm
proimages/technology/reverse_roll.png

Reverse Roll Coating

Application

Features counter-rotating rolls and speed differential control to handle a wide viscosity range, with distinct advantages for non-Newtonian fluids. Wet coat weight is easily fine-tuned via roll gap adjustment.

Features

  • Superior operational flexibility.
  • Wide viscosity compatibility, capable of achieving high coating weights.
  • Surface finish quality can be changed via reverse speed differential regulation.

Reference range of application

  • Viscosity: 200~10,000 cp
  • Wet thickness: 10~200 μm
