Ultrasonics in the Metal Finishing Industry

This industry is a large user of ultrasonics because of the critical need for an absolute clean substrate. Whether applying organic coatings or metal deposits, the adhesion, surface, texture and general appearance of the finished product will be affected by the level of cleaning achieved. Ultrasonics has proved to be the most effective manner to aggressively dislodge and remove the most stubborn solid materials from all metal substrates without damage to even the most fragile component. In most cases, mild detergent process solution can be used instead of strong alkali and solvent cleaners.

Some of the applications are

Electroplating:
Ultrasonics provides easy removal of embedded polishing compounds. It minimises the need for heavy electrolytic cleaning. Ultrasonic water rinsing after chemical processing will minimise metallic and organic contamination carry over to critical process solutions. Damaged plastisol rack coating will be rinsed completely.

Electrophoretic Coating:
Complete removal of solid materials allows full metal contact with the process solution for total paint coverage.

Powder Coating:
Heavy oils and solids can be removed easily using mild cleaning solutions in place of heavy alkalis. This can simplify phosphate and chromate pre-treatment’s

Ultrasonics Eco Cleaning Solutions recommends an Ultrasonic MEGA Tank as the ideal ultrasonic cleaner for the electroplating Industry. If this does not fit your requirements Ultrasonics Eco Cleaning Solutions will create a custom unit to fit your requirements.
