How Medical 3D Printing Benefits from Ultrasonic Cleaning

Hospitals, medical research centers and facilities produce 3D printed models of human body parts or internal organs to create prosthetics for the purposes of surgical procedure, diagnosis, or for educational purposes. Industrial ultrasonic cleaners are now being used to ensure that parts manufactured for medical use are ready for use.

3D-printed models of human body parts and organs are made with build material. The support material, on the other hand, holds the build material until the latter has hardened and self-supporting, and then the support material must be removed to ensure model accuracy. This is where industrial ultrasonic cleaners are used to provide precise cleaning without damaging the material being cleaned.

The ultrasonic cleaning system uses a generator that produces an ultrasonic electrical signal. The transducer, then, converts this signal into ultrasonic waves that travel through the cleaning solution inside the tank. Microscopic cavitation bubbles form from the waves, and then collapse in the pressure peaks.

The cavitation bubbles encounter the support material and effectively dislodge it from the build material. The great thing about ultrasonic cleaning is that it doesn’t cause any damage to the build material that is being cleaned.

Depending on the 3D model being cleaned, Kaijo’s industrial ultrasonic cleaners can operate at frequencies delivering the precise cleaning strength. Lower frequencies (26 kHz or 38 kHz) produce larger cavitation bubbles which perform a more robust cleaning action on typical 3D models. For more cleaning delicate models or models with fragile material, higher frequencies (450 kHz or 950 kHz) are used to produce smaller bubbles which deliver a gentler cleaning action.

Medical 3D models benefit from ultrasonic cleaning. First, it does rapid and thorough cleaning of support material. Second, it is free from human errors. Third, no harsh chemicals or scrubbing is involved. And fourth, disposal of wastes doesn’t require additional measures.

Why Use Ultrasonic Cleaning Systems with a Heater?

Ultrasonic cleaning systems can remove a wide variety of contaminants from the surfaces of parts that need to be cleaned, however removing certain kinds of contaminants require more time than other cleaning applications.

The performance of an ultrasonic cleaning system depends on the parts to be cleaned and the type of the contaminants that have to be removed. For instance, robust parts like automotive components can be typically cleaned in plain water, using the strong cleaning action of the lower frequencies (which produce larger and more energetic bubbles for more robust cleaning). More delicate and fragile parts like semiconductor wafers are usually cleaned using higher frequencies (which produce smaller and less energetic cavitation bubbles for delicate cleaning).

But sometimes, cavitation bubbles alone are not enough to remove tough deposits such as oil-based dirt and grease. That’s where additional measures like a mild detergent and heat come into the picture.

In some cases, a combination of a mild detergent and heat can be tailored to a particular object, and the proper selection can help in improving the ultrasonic cleaning system‘s performance significantly. The detergent increases the solubility of the contaminants while heat softens them. The heat increases the effectiveness of the detergent. These measures will help in removing these contaminants quickly and completely.

Kaijo’s ultrasonic cleaning systems consist of ultrasonic generators (which produce the ultrasonic signal and are selected depending on the frequency needed for the cleaning application), transducers (which should be matched to work with the selected generator), and a tank (which holds the bath and the objects to be cleaned in it).

For cleaning applications requiring heat, both the transducer and the tank should be designed for a heated cleaning solution. Typical temperatures range from 80 degrees Centigrade (or 176 degrees Fahrenheit). Kaijo’s ultrasonic transducers and tanks can accommodate heating requirements up to 100 degrees centigrade (212 degrees Fahrenheit) and the company will work with customers to select right equipment and systems from their full line of products.

How Ultrasonic Cleaning Systems Promote Profitability

Having an effective cleaning process is essential to many industries. In recent years many companies have made the switch from degreasing and other conventional cleaning processes to a more cost-effective cleaning approach.

The chemicals involved in the conventional cleaning process and are expensive to buy and also need to be safely stored. Another consideration for choosing a new cleaning method is the protection of workers who use these chemicals, plus the safe disposal of toxic waste adds further expense. Other industries need to find alternative cleaning alternatives due to environmental concerns.

In industries that require cleaning of industrial parts and equipment, ultrasonic cleaning systems have emerged as a preferred alternative to traditional cleaning methods. These systems utilize ultrasonic energy to clean contaminated tools or parts.

Ultrasonic energy works rather simply – when dense, elastic media such as water is subjected to high-frequency energy, it expands and contracts quickly as to cause millions of microscopic fractures or tears. The microscopic bubbles that are created form and collapse so quickly that they create a great force. When these bubbles touch close to the surface of an object, the force can knock the contaminants off the surface.

Ultrasonic cleaners consist of a tank that is usually filled with water. A transducer can generate high-energy ultrasonic frequencies between 20 to 200 kHz. When contaminated items are a placed in a bath inside the tank, the ultrasonic waves from the transducer generate millions of tiny cavitation bubbles which do the cleaning action. Depending on the frequency chosen, ultrasonic cleaning systems can do effective cleaning on all parts that range from machinery tools to delicate medical equipment.

Ultrasonic cleaning systems are cost-effective but are also a fast, powerful and safe choice for even the most challenging cleaning applications. It needs little supervision and does not require cleaning with chemicals or the need toxic waste disposal. Since there are very few moving parts ultrasonic cleaners require little maintenance as well.

How Utility Companies Cut Grease, Grime and Costs with Ultrasonic Cleaners

The large compressors are usually used by utility companies to move natural gas through pipelines into storage. The compressors themselves, as well as the engines that drive them, are exposed to a lot of grease, grime and deposits and thus require extensive cleaning and maintenance.

Many utility companies use conventional methods of cleaning those heavily and hardened grease- and oil-based components. However, industrial ultrasonic cleaners now offer a better alternative solution to traditional cleaning methods. They use powerful ultrasonic generators and transducers to generate microscopic bubbles in the cleaning solution. These bubbles act as “scrubbers” which cleans parts quickly and thoroughly.

Traditional cleaning methods use strong cleaning chemicals which may corrode or damage the surface of the parts being cleaned. Using industrial ultrasonic cleaners on the other hand only requires a gentle water-based cleaning solution to clean parts. A mild detergent may also added, and/or the solution can be heated if needed for cleaning off grease and oil-based materials.

Unlike manual scrubbing, microscopic bubbles generated by ultrasonic cleaners can reach inaccessible interior surfaces (such as holes, bolt threads and deep crevices) of the parts being cleaned. The result? When a part is submerged in the ultrasonic tank all surfaces are cleaned equally and completely.

Using industrial ultrasonic cleaners will significantly reduce the need to soak soiled materials in a harsh cleaning solution. Not only will ultrasonic cleaning system will save you time, it will also save you money as well. When machine parts are cleaned down to the bare metal throughout, maintenance is more effective, easier to carry out and provides improved reliability for the compressors and engines. Parts that are completely clean will usually have a longer life and extend the lifetime of the corresponding machines. Overall facility operating performance will be more cost-effective and energy-efficient.

The Power behind Ultrasonic Cleaning Systems

Ultrasonic cleaning systems offer an ideal alternative to the traditional cleaning methods, which apply substances or physical contact such as using harsh chemicals or mechanical scrubbing.

But an ultrasonic cleaning system, as the name implies, uses sound rather than substance or scrubbing. It utilizes the principle of cavitation in cleaning contaminated tools and parts.

The principle of cavitation refers to a phenomenon in which disturbances in liquids lead to the creation of short-lived cavities bubbles of gas or vacuum. When the bubbles reach high levels of energy, the bubbles implode and generate a considerable amount of force. The impact created by the imploding bubbles powers the ultrasonic cleaning method.

An ultrasonic cleaning system consists of a tank fitted with a special loudspeaker (transducer) which generates the high-energy ultrasonic waves. As the waves pass through a liquid of water, they reach a desired level of disturbance which leads to the formation of millions of tiny bubbles. As these bubbles form and implode many times each second, they create the cavitation energy needed to dislodge dirt, grease, and grime of the article immersed in the cleaning tank. Despite being tough and effective in removing dirt because of the cavitation energy, these bubbles otherwise will not damage even the most delicate tools.

Kajjo’s ultrasonic cleaning systems offer versatile cleaning ability which are also cost-effective and energy-efficient. A unit has a transducer which produces ultrasonic energy that range from 20 kHz to 1.5 MHz.  These systems employ piezoelectric transducer technology which promises – and delivers – superior cleaning performance over a wider range than other technologies. Piezoelectric transducer technology is far more suitable for ultrasonic cleaning because it has the ability to create ultrasonic sound energy at very high frequencies.

Using Ultrasonic Cleaning for Fuel Injectors

There are traditional methods of cleaning fuel injectors such as soaking them in harsh chemicals, forcing solvents through the injector at high pressure, or removing the deposits manually. These traditional cleaning methods do not guarantee the complete removal of deposits, and they may even damage the injector.

Ultrasonic cleaning systems, on the other hand, do not involve the use of harsh solvents or slow, manual cleaning. Furthermore, it is an excellent alternative that doesn’t suffer from the same drawbacks and it cleans items — even fuel injectors heavy with deposits — quickly and thoroughly.

A fuel injector is placed in a cleaning tank that has an ultrasonic transducer installed at the bottom or on the walls (a portable transducer can also be used in the cleaning solution).

The ultrasonic transducer is powered by an ultrasonic generator that supplies the high-frequency electrical signal (the normal signal is usually 30 kHz). The ultrasonic cleaning system transducer generates ultrasonic waves in the cleaning solution, causing them to produce cavitation bubbles. These bubbles act as cleaning agents for hard metal surfaces like those of fuel injectors. When the bubbles collapse, they dislodge contaminants and deposits from the surface of fuel injectors.

The bubbles travel wherever the cleaning solution is present, so ultrasonic cleaning works outside, inside and in every part of fuel injectors. It even cleans hard-to-reach places, something that traditional cleaning cannot do. As a result, the deposits are removed from inside fuel injector holes, from threads, and from couplings. All foreign material is removed and cleaned down to the bare metal. Ultrasonic cleaning is also fast, taking from 10 to 20 minutes for the cleaning cycle.

3 Big Cost Savings Benefits of Using Ultrasonic Cleaners vs. Spray Washers

 

If there’s one thing that business and facilities owners want when they’re considering a cleaning solution, it should be cost-effective.

Ultrasonic cleaners provide an excellent cleaning alternative to other traditional methods of cleaning, like spray washers. Ultrasonic cleaners can clean anything from delicate medical parts to machine parts, and everything in between.

But there are also other ways that business owners can benefit from using ultrasonic cleaners as opposed to spray washers, in relation to the cost:

 

  1. Save on materials
    Spray washers rely on large amounts of chemicals to clean stains and require operators to use protective equipment. These concerns are non-existent with ultrasonic cleaners. Cleaning with high-frequency pressure waves does not require chemical action to loosen stains. While it requires a mild detergent to help loosen the most stubborn stains, it is otherwise inexpensive when compared to the number of chemicals used in spray washers.
  2. Save on labor costs
    The ultrasonic waves generated by these cleaners do not need to be directly aimed at surfaces to be cleaned. The microscopic bubbles travel in every nook and cranny of the tools and parts being cleaned, assuring thorough cleaning. With ultrasonic cleaning, the parts become cleaner with less effort.
  3. Save on maintenance
    Spray washers may require lots of energy to operate. It has moving parts as well that require expensive maintenance — if they cannot be maintained regularly, they would eventually lose their usefulness. Customized ultrasonic cleaners do not require much maintenance — they don’t come with moving parts — all you have is a transducer and a bath of liquid. With very little maintenance, ultrasonic cleaning systems are guaranteed to last a lifetime
