Ultrasonic Cleaners

Ultrasonic cleaners utilize high-frequency sound frequencies of about 18 kHz in order to cause cavitation, or the formation and implosion of minuscule bubbles in a liquid cleaning medium. These bubbles, or implosions, serve as cleaning agents to rid parts of small dirt particles that reside in crevices and surface areas that would otherwise be impossible to reach. However, because ultrasonic cleaning is not intended for large particle cleaning, parts must first be cleaned by other methods before they are ready to undergo ultrasonic parts cleaning.

Offering precision and consistency, ultrasonic cleaning equipment removes soil and contamination from parts more rapidly than any conventional cleaning method. There are several types of application-specific ultrasonic cleaners. Ultrasonic blind cleaners are specifically designed to rid blinds such as mini blinds, verticals, duettes and pleated shades from nasty contaminates like dirt, grease, nicotine and fingerprints. Ultrasonic jewelry cleaners remove dirt and other contaminates from various jewelry such as rings, necklaces, bracelets and earrings. Golf club cleaners clean the golf clubs, including the grips, from dirt buildup that occurs on through use on the golf course. Ultrasonic degreasers are contaminate-specific, targeting grease in automotive equipment and parts processing. Ultrasonic cleaners typically are used to eliminate such contaminates as sludge, buffing and polishing compounds, mold release agents and oil.

Different types of ultrasonic washers have designs that are uniquely suited to their specific function. Ultrasonic jewelry cleaners, for instance, are much smaller than industrial ultrasonic cleaners since they are typically for commercial and personal use only. Ultrasonic jewelry cleaners are designed with a small tank containment basket and pressure controls located on the outside of the tank. Ultrasonic jewelry cleaners are typically powered by ultrasonic transducers, though some portable cleaners may be battery operated. Ultrasonic blind cleaners consist of a generator, transducer and a fairly large tank that can be made portable by attaching casters, depending on the size of the tank. The blinds are placed in the place the tank, which is filled with hot soapy water and injected with powerful sound waves that gently clean the various parts of the blind including slats, cords, and the head rail. Golf club cleaners differ from other ultrasonic cleaning equipment due to vertically-aligned tanks, which are necessitated by the length of the golf clubs that must fit in the tank to be cleaned. Ultrasonic golf club cleaners may also become portable through the addition of casters. Ultrasonic degreasers have a similar construction as ultrasonic blind cleaners, but they typically have an ultrasonic transducer mounted at the base of the tank that can reach sounds of up to 20 to 40 kHZ.

All ultrasonic cleaning equipment is at minimum equipped with a transducer, a generator and an immersion tank. The part requiring cleaning is placed into the tank, which contains an ultrasound conductive fluid. There are three different cleaning mediums commonly used: hot water cleaning, which uses a heated water stream; aqueous cleaning, which uses a water-based ultrasonic cleaning solution; and solvent or vapor cleaning, in which the solvent is evaporated then condensed onto the surface of the parts. The ultrasonic cleaning process begins when there is cavitation. Cavitation is caused by the transducer, which can be either attached to the tank or lowered into the fluid, when the transducer introduces ultrasonic sound waves into the tank. The agitation caused by the innumerable minute and intense imploding bubbles release both energy and heat that provides a highly efficient method of scrubbing both exposed and concealed surfaces of the immersed parts. There is a direct correlation between how high the frequency is and the number of implosions. However, the energy released by each implosion is also affected and decreases; this makes high frequencies ideal for minute particle removal with no harm to the part's surface. Materials commonly cleaned by the ultrasonic cleaning process include stainless steel, iron, aluminum, copper, brass, plastics, rubber, wood and cloth.

New developments for ultrasonic cleaning equipment include automated ultrasonic cleaning systems. These fully-automated systems incorporate a variety of cleaning actions such as power spraying, rinsing, precision flushing and drying parts. These processes are achieved at high rates of speed, which results in zero-residue cleaning when the ultrasonic cleaner is equipped or attached to deionized water. In addition, because rinsing is performed in the same tank as is the ultrasonic cleaning process, the rinse is already ultrasonic and there is no additional cost to add ultrasonic components to a rinse tank, as is the case with a multi-tank cleaning system. Fully-automated ultrasonic cleaners improve upon conventional models of ultrasonic cleaning equipment because they increase pre-assembly cleaning quality and cut solvent use by ninety percent. These improvements are the result of harnessing heat pump thermal transfer techniques which serve to minimize solvent evaporation that occurs overnight. Combined with diagnostic process control, full-automated ultrasonic cleaners offer a dedicated computerized work transporter that facilitates, establishes and maintains optimal performance levels.

Ultrasonic waves hit the (layer of) contaminants from various angles, which removes them from the surface, and provides simple cleaning, making ultrasonic washers undeniably a great tool for manufacturing industries.

Buying Ultrasonic Cleaner-a Comprehensive Guide

Ultrasonic cleaners are tremendous equipment for detailed and thorough cleaning of complex and intricate metal parts. They become important when all other available options fail to give optimum results, or fail to clean delicate and expensive parts with efficiency and without any damage. These are their unique selling points. Moreover, the thorough and efficient cleaning ability of ultrasonic cleaners has made them the preferred tool for cleaning of medical equipment and apparatus.

How do they work?

As the name suggests, an ultrasonic cleaner uses ultrasonic sound waves, basically, to rub off the buildup or dirt from the surface of metal parts. Ultrasonic Parts Cleaners are filled with a solvent bath and the part to be cleaned is immersed in the bath. The walls are installed with transducers that emit the pulses of high frequency sound waves, causing cavitation, a fluid process that produces small bubbles that repeatedly attack the solid surface of the parts to be cleaned. The bubbles act as scrubbers that remove the flux or build up from the surface of the parts.

Ultrasonic cleaning solution has a range of applications; however, it is commonly used for jewelry, delicate parts for electronics, industrial manufacturing, as well as medical and dental instruments.

Tips to buy an ultrasonic cleaner

The first step is to determine what is to be cleaned. Ultrasonic cleaning equipment comes with a multitude of tub sizes, therefore, the shape and size of the parts to be cleaned should be considered first. The quantity of parts that will be cleaned in a batch should be taken in to account too.

Selecting a general or common cleaner

  • General-purpose ultrasonic parts washers have application in jewelry and medical equipment industries.
  • The ultrasonic tanks can vary in size; they have capacity from around a half gallon (1.9 liters) to 6 gallons, which is equal to 22.7 liters.
  • The cost of these general-purpose cleaners ranges from $500 to $1,500.

Choosing a high-capacity ultrasonic cleaner

  • High capacity ultrasonic cleaners are suited for cleaning industrial parts, including gun parts and electronic parts.
  • The capacity of cleaning tanks are commonly around 10 gallons, which equals to 37.9 liters.
  • These are more like ultrasonic washing machines that cost approximately $4,000, which even work as an ultrasonic degreaser.
  • Given their application in the heavy industry, they are significantly sturdier than standard cleaners are and can withstand rough handling.

Special type cleaners

  • To clean pipettes, an apparatus commonly used for the drawing and depositing of fluid samples in medical and scientific laboratories, a custom ultrasonic cleaner is used, as substance left in the pipettes can be hazardous and need additional tools to handle it.
  • The cost of these special types of ultrasonic cleaners is a bit on the higher side; expect to pay about $1,000 to $1,500.

Additional information

You can buy ultrasonic cleaners through various vendors; however, they are readily available online through various manufacturers. You can have save money by buying through the Internet, but ensure that the after sales services and maintenance assistance is available in your region.

Understanding the Various Types of Industrial Ultrasonic Cleaners

Ultrasonic parts washers are available in a wide variety, ranging from small, home or office purpose devices to large-scale industrial appliances. Industrial ultrasonic cleaners work by creating high-frequency sound waves to lift debris and pollutants on the surface of an object that is intended to be cleaned. In addition to employing an ultrasound wave, the device also makes use of a customized solution to clean dirt from the industrial parts.

Additionally, this device also has a robust heater that warms the cleaning solution in the tank. Sometimes, ultrasonic washers can also have more than one sink and an automation feature to ease and automate the entire operation. At times, with industrial ultrasonic parts washers, ultrasonic transducers are also used to improve efficiency. That is how custom ultrasonic are designed. Immersible ultrasonic cleaners are also available, which offer many advantages including high flexibility and ease of operation, installation, and endurance.

During most of the cleaning processes, clearing all the pollutants, cavities, debris, etc. is a desirable outcome. The mechanical effects of ultrasonic sound waves can be used to achieve this objective. These powerful sound waves vibrate, dissipate and displace waste products and impurities. Moreover, toxic chemicals and gaseous elements can also be removed through this cleaning process.

Many times, the physical structure or molecular bonding of contaminants can be complex. Such complex combinations may contain soils composed of soluble and insoluble constituents. By making adjustments to the control panel of ultrasonic cleaner, these components can also be removed during the cleaning process. However, this typically requires a stronger sound wave.

Further, to achieve a more efficient cleaning, ultrasonic transducers can be introduced in conventional cleaning systems. This way, such cleaning devices will perform cleaning using the rigor of ultrasonic energy. The transducer converts the energy driven by the electric current into high-frequency mechanical vibrations.

These transducers are technically called ultrasonic generators, as they create the power of ultrasound waves. To be specific, these generators can translate 50 to 60 Hz of electric current into mechanical force or ultrasonic energy. Modern-day transducers come with an innovative feature that allows you to set the output parameters or customize the energy output according to your application requirements.

Typically, there are two types of ultrasonic transducers-magnetostrictive and piezoelectric- used by today's manufacturers. Both the mechanisms have the same use-to convert electrical energy into ultrasonic energy.

By pairing an ultrasonic cleaner with a square wave signal, you can turn your normal cleaning system into a multi-frequency cleaning system with which you can work on a variety of contaminants using a diversity of vibrations and frequencies.

The amount of time for which the ultrasonic wave remains engaged can be changed to meet desired cleaning outcomes. The frequency output of your ultrasonic generator can be moderated using a central frequency.

How to Run Ultrasonic Cleaning Equipment Optimally

Other than the conventional parts washers, these days, many industries, where quality matters, are using ultrasonic cleaning equipment. They are used in a variety of manufacturing and maintenance processes, improving quality of products.

Ultrasonic cleaners generate millions of microscopic bubbles per second through cavitation, which removes debris or dirt from hard metallic surfaces. The process efficiently cleans the complex shapes and design, reaching intricate spaces easily and effortlessly.

Here, we will discuss some practices that will help you to run ultrasonic cleaning equipment optimally:

  1. Proper Cleansing Agent
  2. To clean different types of contaminants, you need specific types of ultrasonic cleaning solution.

    • Alkaline solutions
    • Cleaning contaminants, like oil, light grease, dirt, soil, or carbon, require an alkaline soap, with high pH. Alkaline solutions can clean almost anything; however, it can damage softer metals, like aluminum. It is suited for hard metals, such as stainless steel and titanium. Stain prone steel and other ferrous metals should not be washed with water-based solution; they need a built-in rust inhibitor and rinsed in a rust inhibitor to be washed effectively, without any harm to the metal.

    • Acidic solution
    • To clean water-damaged metals, contaminated with calcium deposits or rust, an acidic cleansing agent is better suited. It not only removes the top layer of metal surfaces, but also shines the metal surface.

    • Neutral solution
    • Delicate parts, such as electronics parts, need neutral pH soap; a neutral pH cleaning solution does not damage copper filaments or thin layers of metal. Mainly it is used in ultrasonic jewelry cleaners. Neutral pH cleaning solutions are fine for parts with light surface contamination such as dust or light dirt particles.

  3. Right temperature
  4. Industrial ultrasonic parts washers work optimally in 135 degrees F to 150 degrees F range. The temperature range softens and loosens contaminants and is important to achieve effective microscopic level cleaning. However, temperature above the range can accelerate evaporation, which can damage softer metals.

    For removing burned-on carbon from metal surfaces, temperatures as high as 180 degrees F is required, whereas for delicate parts, including electronics, temperatures below 150 degrees F is appropriate.

    For some critical applications, lower temperatures are deemed more appropriate. However, in such cases the washing period is elongated to compensate for lower temperature.

  5. Right watt density
  6. Ultrasonic watt density, a measure of how much ultrasonic power is available in a tank against liquid volume, is an important factor in ultrasonic cleaning.

    Generally, lighter metal parts with lower degree of contamination require less power, while larger parts require more power. However, in general, 25 watts per gallon is right for cleaning tanks with capacity of 40 gallons.

    Interestingly, ultrasonic parts washers with smaller tanks require higher watt density.

  7. Right output frequency
  8. Standard ultrasonic washers work at 40 kHz, or 40,000 cycles per second. In such washers, each transducer creates 40,000 microscopic bubbles per second. The 40-kHz rate is considered effective at cleaning; it also maximizes equipment life expectancy.

    Washers that have application in heavy industry work at a frequency of 20 kHz to 25 kHz, creating fewer bubbles but stronger, and stronger bubbles are more effective for cleaning bigger parts.

    For cleaning sub-micron contaminants, like those on medical or electronic parts, frequencies as high as 68 kHz or 170 kHz is used, creating bubbles at a greater rate, which helps to clean smaller debris.

What to Look for while Buying Used Ultrasonic Cleaning Equipment?

New ultrasonic cleaning equipment, mainly industrial-sized, is expensive, so it makes sense to purchase a used unit.

Here we discuss the factors that you should consider while acquiring a second-hand ultrasonic cleaning system.

First Factor

Ultrasonic cleaning units are basically made up of a tank, an ultrasonic generator, and ultrasonic transducers, which are fixed to the bottom of the tank. Any mechanical force acted upon it can damage the unit irreversibly; therefore, the first thing that you have to care about is if the unit has been dropped. To tell if a unit has been dropped check for dents, if you find any, look for other options.

Second Factor

The most common defect with used ultrasonic parts cleaners is heat damage. Ultrasonic transducers release quite a bit of heat, which is dispersed by the liquid or solution in the tank, and running a unit with a low-level of solvent can effectively damage the bonding between the transducers and the tank, preventing cavitation. To check for heat damage, see there is any discoloration on the housing. Excessive discoloration signals bad handling of the machine. Do not buy it.

Third Factor

A bad practice among operators is to put parts directly at the bottom of equipment's tank, which damages the transducers. The right practice is to use a basket instead. If an ultrasonic cleaner is offered without a basket, enquire about the basket. If it is missing, it is an indicator that machine has been used badly, which cuts the life of a machine significantly. It is better not to invest money in such ultrasonic cleaning unit.

Fourth Factor

Ask for all the documentation, this will give you all the important information you need, from functional properties, to model, to competencies, to date of purchase. All this information will you help to determine if the ultrasonic washing machine will serve your requirements.

All these factors are accumulated with the help of an expert, if a machine passes all these considerations, buy it.
