Dip Coating Unit

Category: Tag:

Automatic unit for controlled dip coating process for precise thin film deposition onto flat, cylindrical and odd-shapes substrates.


Dip coating refers to the immersing of a substrate into a tank containing coating material, removing the piece from the tank, and allowing it to drain.

The process is carried out with well-defined speed under controlled temperature and atmospheric conditions. The coating thickness is mainly defined by the withdrawal speed, by the solid content and the viscosity of the liquid. Owing to its simplicity, this method lends itself to automation.

Stage of Dip Coating

The dip coating process can be, generally, separated into 3 stages:

  • Immersion: the substrate is immersed in the solution of the coating material at a constant speed preferably judder free
  • Dwell time: the substrate remains fully immersed and motionless to allow for the coating material to apply itself to the substrate
  • Withdrawal: the substrate is withdrawn at a constant speed to avoid any judders. The faster the substrate is withdrawn from the tank the thicker the coating material that will be applied to the board
