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.
Carolina Filters 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.
