Ultrasonic ShadowingThe ultrasonic cleaning process uses a combination of ultrasound and water and/or parts cleaning solvent to clean a wide variety of component parts and assemblies. Ultrasonic cleaning is especially effective for delicate or complex parts.

During the ultrasonic cleaning process cavitation bubbles induced by high frequency sound waves are used to agitate the parts cleaning liquid. The agitation releases contaminants adhering to substrates such as plastic, metal, glass, ceramics, and rubber. The ultrasonic cleaning process allows the cleaning solution to penetrate blind holes, cracks, and recesses is to thoroughly remove all traces of contamination tightly adhering or embedded onto solid surfaces.

While ultrasonic cleaning is highly effective, the issue of “ultrasonic shadowing” can impair the thoroughness of this type of cleaning. Ultrasonic shadowing occurs when the parts being cleaned are positioned in a manner that casts an “ultrasonic shadow” on some of the other parts. This shadow prevents covered parts from being effectively cleaned.  Though ultrasonic shadowing is known to occur, it can be difficult to define and predict.

Unlike the shadow cast by a solid object illuminated by the sun or a lightbulb, an ultrasonic shadow is not distinct in shape. Ultrasonic shadows are more like the shadows cast by diffused light, like the sun shining on a cloudy day, where the darkened area is less distinctly defined.

Blackstone-NEY Ultrasonics Robosonic Robotic Precision Cleaning Cell to be Introduced at IMTSBlackstone-NEY Ultrasonics is excited to debut the newest of our many innovative cleaning technologies at the upcoming IMTS conference. Our exhibit will provide attendees with a first look at our new Robosonic Robotic Precision Cleaning Cell.

The Robosonic Cleaning Cell is a four-tank system that includes a spray wash, ultrasonic immersion wash, ultrasonic rinse tank and dryer. The robotic operation is provided by a Fanuc CR-7i. Fanuc is a trusted industry leader in robotic technology.

Robosonic features include:

CTG will be exhibiting a variety of innovative cleaning technologies at the upcoming IMTS conference to be held in Chicago, Illinois. The International Manufacturing Technology Show (IMTS), happening at McCormick Place, September 10 – 15th, is the premier manufacturing technology show in North America, bringing together buyers and sellers from 117 countries.

The Rotosonic Combination Spray and Ultrasonic Cleaning System will thoroughly clean heavily soiled parts in a one system for maximum cleaning efficiency.

Among the systems displayed in the CTG booth will be our new Rotosonic™ Combination Spray and Ultrasonic Cleaning System. This automated ultrasonic cleaning system provides maximum cleaning efficiency through the use of high-pressure spray, part rotation, and ultrasonic energy. The Rotosonic will thoroughly clean heavily soiled parts in a one system, eliminating the need to purchase a spray cabinet and an ultrasonic machine separately. The Rotosonic provides the ultimate in flexibility in that it can either perform a single process or both processes, depending on your needs. The machine features a compact design, and eliminates the required labor and safety risks associated with moving parts from washer to washer.

Typical Applications:

Among the many innovative cleaning technologies CTG will be exhibiting at the upcoming IMTS conference will be our LeanJet® RB-2 Automated Immersion Cleaning System and our LeanJet® Cell-Jet.

LeanJet RB-2 AutomatedCell-JetOur LeanJet  RB-2 Automated immersion cleaning system incorporates two (2) industrial standard size baskets of parts per cycle, cleaning up to twenty (20) baskets per hour. This system cleans parts by using a washing and rinsing process of agitation, spray impingement, hydraulic purging through immersion and rotation, ultrasonics, and heated blow-off drying. Engineered specifically to process a broad range of challenging parts, the "triple action" batch cleaning process is especially effective for cleaning parts with internal bores and passages and complex geometries. The LeanJet RB-2 is  capable of meeting the most critical cleaning requirements. Customer specific basket designs are available to accommodate larger parts.

Aquarius™ Series Multi-tank Ultrasonic Cleaning SystemsCTG will be exhibiting many innovative cleaning technologies at the upcoming IMTS conference to be held in Chicago, Illinois. Among the systems displayed will be our Aquarius™ Series Multi-Tank Ultrasonic Cleaning Systems. This efficient high performance system combines ultrasonic cleaning with rinsing, drying, and other processing steps into a consolidated cleaning system to promote process integrity.

This combination system features automated robotic transfer, environmental enclosure, and DI water system to increase cleanliness levels. This design also provides process consistency while significantly reducing the labor required for parts cleaning.

The cost-effective Aquarius Series Multi-tank Ultrasonic Cleaning Systems are pre-engineered to meet a variety of parts cleaning needs.  This platform can also be employed to handle any nitric or citric acid passivation requirements.

Typical Applications:

Ultrasonic Parts Cleaners – More Power Doesn’t Always Mean It’s BetterWhen comparing parts cleaning equipment, you will most likely be looking at a number of factors including the amount of power offered by each system. In the case of ultrasonic cleaning equipment, more power does not necessarily mean the parts cleaner will provide more for your money.  

In some cases, high-powered ultrasonic cleaning systems are needed to do a particular job, but more commonly an assumption is made that more energy is better when it actually is not. In order to understand why more power in an ultrasonic parts cleaning is not always advantageous, you must consider the design, as it relates to ultrasonic transducers and cleaning.

The ultrasonic devices used in an ultrasonic parts cleaner incorporate a number of individual vibrators attached to a plate or diaphragm. A liquid media is contained on the other side of the plate. When the vibrators activate the plate, the vibration produces sound waves in that liquid media. The vibrators depend on resonance at a certain frequency to deliver the required amplitude for vibration to create the cavitation and implosion in the liquid that does the cleaning. The individual vibrators are able to convert about 40 watts of electrical energy into mechanical energy as vibration.
