How does ultrasonic cleaning work?

High-frequency sound waves create cavitation bubbles in a liquid, effectively removing contaminants from surfaces.

What are the benefits of ultrasonic cleaning?

It reaches intricate geometries and provides thorough cleaning without mechanical damage.

Which industries benefit from ultrasonic cleaning?

Parts and filters made of durable metallurgy and surface level contamination benefit from the use of ultrasonic cleaning.

Are there any parts that are not appropriate for Ultrasonic Cleaning?

Parts with contaminations that are deeply embedded inside complex deometries or with contaminates which are chemically bonded may not fully respond to Ultrasonic cleaning alone.

Ultrasonic Cleaning

How it works

Ultrasonic cleaning is a commonly used method for surface cleaning of metallic components. By submerging parts in an appropriate ultrasonic bath, sound waves, composed of rarefactions and compressions, create imploding vacuum bubbles, also known as "cavitation," which removes surface contaminants and creates visually appealing parts.

What we do

Carolina PEC uses ultrasonic cleaning for specific applications, such as polymer melt filters with high additive loads, wire mesh screens that are heavily contaminated, porous metal cartridges with embedded particulate/catalyst fines, and scale-coated dies and spinnerets. By considering frequency, chemistry, process time, bath temperature, and positioning, ultrasonic processes can be developed for specific applications. While not ideal for all components and filters, ultrasonic cleaning can be effective when used properly to allow for physical/chemical removal of particulates.

“Carolina Filters looks for alternate means of cleaning more than other companies do. The other companies are stagnant on how they clean whereas Carolina tries hard to lessen their environmental footprint. It is always important to try to take care of the environment so that is important to us. Carolina Filters is always looking for new processes and new ways to refine and improve their cleaning expertise.”
