Chemical Surface Treatment Plant

The common feature of chemical treatments is to clean the surface of the steel, remove surface contaminants and improve corrosion resistance.

RAK ENGINEERING’s chemical treatment line are typically in compact-sized for small to medium sized parts or components. All lines are pre-assembled and tested at out site before delivery to customer.

Typical type of Chemical process treatments:

• Degreasing : Removing oily substances and any residual grease from metal surface
• Acid Pickling : Removing any impurities and the layer of surface oxide from other manufacturing processes.
• Passivation : To restore the corrosion protective oxide layer for metal surface
• Electropolishing: A process after degreasing, pickling and passivation. Removing a thin surface layer from a material that gives the surface clean, shiny and smooth
• Stripping and Etching : Removes particles which can flake a plate-layer and common for remove metals base layer
  
• Phosphating : A chemical method of surface treatment for corrosion protection, reduction of wear and electrical insulation
• chromate coating (Chromating) : A corrosion resistant process that preventing oxidation on metals or as a base for painting.
