Ultrasonic Cleaning

Precision Cleaning Ultrasonically

Ultrasonic cleaning effectively removes small particulate and adhering contamination from parts that have entrapment areas that are hard to access through mechanical means. The sound wave energy, generated by transducers placed somewhere in or adjacent to an elastic medium (like water), cause negative pressure, which in turn causes the liquid to fracture and cavitation "bubbles" to occur. The "bubbles" oscillate under the influence of positive pressure, grow to an unstable size, collapse, and create implosions. The implosion sites cause temperatures in excess of 10,000°F (5,535°C) and pressures in excess of 10,000 psi (68,950 kPa). At the right temperature, with the right solvent and at the right frequency this ultrasonic cleaning effectively removes contaminants. Additionally, agitation created by the forces helps speed the dissolution of soluble contaminants and the displacement of insoluble particles.

Maximizing Effectiveness of Ultrasonic Cleaning

Cleaning effectiveness depends on matching the right frequency to the right cleaning task, choosing the right solvents, and checking the sound wave generators for output on a regular basis. As many as 70% of parts see ultrasonic cleaning at some point in the precision cleaning cycle. Over the last two decades as ultrasonic cleaning has become the norm, NTS has compiled an impressive record in ultrasonically cleaning all types of aerospace, medical, electronic, and commercial parts. Currently, NTS operates four ultrasonic cleaners with sizes up to 4 ft³; the equipment set-up is designed to handle a wide range of ultrasonic cleaning tasks, including precision cleaning within a cleanroom environment. We understand how the viscosity of a fluid must be minimized while its solvent properties enhanced. We understand the importance of elevated temperatures to aid the process, and our tanks are heated and thermostatically controlled. Moreover, we understand the need to perform thorough rinsing immediately following ultrasonic cleaning with aqueous chemistries. Our experience is your guarantee.

Safety for Your Parts

If you place a thin piece of household aluminum foil in our large ultrasonic cleaning tank, within moments, the tin foil develops visible pinholes. A part unsuitable for ultrasonic cleaning or mismatched to the available power can be irreparably damaged. It takes experience and expertise to ultrasonically clean. NTS personnel uses our decades of experience, our proven process procedures and ultrasonic operating practices, as well as a large assortment of the right accessories (racks, baskets, and containers) to make sure that your parts are cleaned effectively and safely every time.
