Industrial Zinc Flake Coating Machine 7MT Weight Large Working Space

The material for the zinc flake coatings gets supplied in liquid form and needs to be prepared to the desired conditions before application. The viscosity, temperature and stirring time prior to application all play an important role here. The material can be applied using the following application techniques:

• Spraying. The coating material is applied to the parts' surface using a spray gun. This can be done manually or in a fully automated spraying facility (this process is used for larger or unwieldy parts, also termed rack parts, as they are brought into the coating process on a rack).
• Dip-spinning. The parts get loaded into a basket. The coating is done by dipping the basket into a container filled with the prepared coating material. After the dipping, the basket gets spun around in order to remove the residue of the coating material (this process is used for smaller high-volume / bulk parts, also called drum parts).
• Rack-mounted dip-spinning. Parts that are positioned or otherwise fixed in baskets are dipped, spun and passed through the furnace with the rack.
• Dip-drain coating. Dipping the part into the coating material and drawing it out in a set manner enables the inside and outside of, for example, pipes to be coated in a single process. The parts should, however, have sufficient openings that the material can drain away again, otherwise flawless coating is not possible, as the accumulations of the material cause air bubbles to form.
