Why Ultrasonic Cleaning Systems Are Used in the Metal Finishing Industry

Metal finishing involves applying coatings or other kinds of treatments to metal parts surfaces. This is to change the metal part's characteristics, harden the surfaces, or preventing corrosion. Ultrasonic cleaning systems are able to clean these metal surfaces quickly and completely.

These metal finishes include electroplating, which uses an electrode in applying a thin metal film to metal parts; plating using a chemical process; and plating which involves pressing a foil of metal onto part surfaces at high temperature and pressure.

For these metal finishing processes to be successful, the underlying metal surfaces have to be completely clean. Otherwise, the coatings may not adhere properly if the contaminants (such as grease or oil) remain on the metal surface.

Clean and contamination free surfaces allow for the proper adhesion of metal coatings, that's why metal parts must be cleaned completely for the coatings and claddings to adhere. Ultrasonic cleaning systems effectively clean metal surfaces quickly and thoroughly.

In ultrasonic cleaning process metal parts to be coated are immersed in a bath of pure water (or water mixed with a mild detergent). A high-powered ultrasonic generator transmits an electrical signal to an ultrasonic transducer that is placed in the bath and produces ultrasonic waves in the liquid at a selected frequency. The sound waves generate tiny cavitation bubbles that produce a strong scrubbing and cleaning action against the metal surfaces in the bath, dislodging particles and removing contaminants.

Other cleaning methods that use chemicals or mechanical cleaning are often used in metal applications. However, the use of ultrasonic cleaning systems and equipment is faster and does not require the use of harsh cleaning chemicals or intense mechanical scrubbing. Since ultrasonic cleaning requires no chemicals costs are reduced and it is more environmentally friendly.

How Ultrasonic Cleaners Are Used in Flat Panel Glass Processing

The flat panel glass is used in many products including flat screen products. The manufacturing steps in flat panel glass processing involve the application of coatings, adding semiconductor functions and special treatments of the glass. Manufacturing processes also often leave residues and the glass itself can pick up dirt and contaminants from the shop environment. Before it can be processed further, flat panel glass must be effectively and completely cleaned. Industrial ultrasonic cleaners used in these applications only require the use of mild detergents is safe for workers and the environment.

After flat glass sheets have been cut, the edges need to be polished and the corners rounded. The resulting flat panel glass that has a specific size and shape will then go through additional processing.
The additional process steps can include the addition of color or polarizing filters, layers for liquid crystal displays or chip on glass applications. For each of these process steps, having a clean glass surface is essential. Industrial ultrasonic cleaners are essential to the cleaning process to ensure surface contamination is removed and ensure quality flat panel glass products are produced.

While each of the process steps requires cleaning glass panels, the actual cleaning requirements needed for each steep may be different. For rough cleaning and removal of heavy contamination from the glass itself, the strong cleaning action from a low-frequency ultrasonic system may be appropriate. For filter coatings and chip on glass cleaning requirements, however, higher-frequency systems delivering gentle cleaning without damaging delicate films and components may be required. Since there are many cleaning applications in flat panel manufacturing specific requirements and customized ultrasonic systems may be required.
