Electrostatic Coating

Electrostatic coating is the process of painting with positively charged paint particles from a specialized gun to coat metal surfaces which have been grounded to create negatively charged metal surfaces. Working similarly to a magnet, the positively charged paint is drawn to the metal and coats it evenly and effectively with less than 5% waste whereas a standard method can waste as much as 20% to 60% to accomplish the same task. Once applied, the paint takes up to 24 hours to fully dry.

Advantages:

• Easier to coat difficult shapes
• Components do not need to be preheated
• Color changes are far simpler than with fluidized bed coating
• Low cost for automation
• Film thickness between 30-250 microns
  

Disadvantages:

• Equipment cost is far more expensive than with fluidized bed coating
  

Fluidized Bed Coating

This process of coating is a form of spray coating that occurs within a fluidized bed system. To achieve this method, items are placed inside a fluidized bed and moved around while simultaneously being sprayed with a liquid. This method results in an even distribution and provides a protective layer of coating, but does require a greater amount of powders and wasted material.

Advantages:

• Low initial cost to manufacture
• A high film thickness of >250 microns can be applied in one cycle and used as a protective layer
  

Disadvantages:

• Components must be simple in shape and not complex and thin gauge material cannot be coated with this method due to low-heat capacity.
• All pieces must be preheated in order to be worked with
• Color changes can only be accomplished through additional beds
• Film thickness of over 200 microns is average
