No Need for Chemicals -- Ultrasonic Waves Clean in Water

Traditional cleaning of machine parts and components involves using strong chemicals that need to be disposed of and are environmentally hazardous. Industrial ultrasonic cleaners using ultrasonic waves, on the other hand, do not need harsh cleaning chemicals and instead only use plain water to achieve the same results.

Kajio's ultrasonic cleaning systems use an ultrasonic generator to produce high frequency electric signals whose frequency ranges from 20 kHz to 200 kHz. These signals are fed to a transducer which is immersed in the water bath. The transducer vibrates which converts the electrical signal into sound waves in the water.

The sound waves produce tiny cavitation bubbles that appear and collapse. These bubbles scrub the surface they are cleaning and remove contaminants and foreign particles. Low frequencies produce larger bubbles that clean robust materials intensely while high frequencies produce smaller bubbles that are gentler to clean delicate surfaces.

For business owners and managers at manufacturing facilities that are faced with the high cost of using chemicals and complying with environmental regulations, ultrasonic cleaners represent an attractive alternative. In addition to cost savings industrial ultrasonic cleaners operate faster and more effectively than chemicals and solvents. Cleaning with ultrasonic waves is quick, thorough, and mechanical. Ultrasonic waves can also clean small holes and crevices plus do not cause damage to the parts being cleaned.

Kajio's ultrasonic cleaning systems include the Phenix III Turn Key Ultrasonic Cleaning System for both general and specialized industrial use, and as well as the Quava Mini table top ultrasonic system for cleaning smaller delicate parts. Individual parts include ultrasonic generators, transducers and tanks that hold the water where the parts are cleaned.

Customers who want to change from traditional cleaning methods can use the latest ultrasonic technology using one of Kaijo’s industrial ultrasonic cleaners.  Kaijo’s experienced support team will ensure that customers select the best system suited for their particular applications.

Why 40 kHz Ultrasonic Transducers Are Used by Manufacturers in Cleaning Applications

Ultrasonic cleaning systems offer significant advantages to manufacturers over traditional chemical-based cleaning methods. Ultrasonic cleaning systems provide lower operational cost savings since they don’t use harsh cleaning chemicals that require compliance with environmental regulations. They are also clean faster and are more effective in removing surface containments and residues from irregularly-shaped surfaces of components or devices. Before purchasing an ultrasonic system a customer first needs to determine which frequency will work best for their cleaning application.

 

Ultrasonic cleaning systems operate at frequencies that range between 20 kHz and 200 kHz. The cleaning system consists of a generator, transducer and a cleaning tank. The transducer generates ultrasonic waves that produce bubbles in the water of the cleaning tank. At lower frequencies larger bubbles are created that provide more intensive cleaning while smaller bubbles are created at high frequencies which clean more gently. A 40 khz ultrasonic transducer generates mid-range to large bubbles which effectively cleans a wide range of manufactured parts that is needed by manufacturers.

The nature of contamination or dirt on the parts or components to be cleaned will determine which frequency will work best for ultrasonic cleaning. Robust parts that have heavy deposits to be removed will require a lower frequency with intensive cleaning. Delicate parts with only dirty film or microscopic particles will need to be cleaned at high frequencies. The mid-range 40 khz ultrasonic transducer combines the most desirable features of both extremes.

In cleaning applications an ultrasonic transducer operating at 40 kHz can effectively clean industrial devices, machined parts, ceramics, jewelry, hard disk drive parts, wires and glass parts such as lenses. Both light films heavy contaminations are effectively removed without damaging the surface of the parts that are cleaned.

Kajio’s 40 khz Ultrasonic Transducer is available in immersible, bolt-on, and tank-mounted configurations. To learn more about the 40kHz ultrasonic transducers, read the main article on Kaijo’s website entitled “Why 40kHz Ultrasonic Transducers Are Used by Manufacturers in Cleaning Applications.”

Why a Mini Ultrasonic Generator System May Be the Best Choice for Your Device Cleaning Requirements

Ultrasonic cleaning is a fast, effective, practical, and environmentally-friendly alternative to cleaning objects using harsh chemicals and scrubbing. An ultrasonic generator with low ultrasonic frequency can produce large cavitation bubbles which clean stains and impurities with robust action while a high-frequency cleaning produces smaller cavitation bubbles and less intense cleaning action, ideal for gentler cleaning tasks.

Kaijo's Quava Mini ultrasonic generator is able to clean small parts using a wide frequency range depending on the cleaning task, making it ideal for all-purpose cleaning. The Quava Mini can be used by facilities that either clean a variety of components or have specific cleaning requirements.

The Quava Mini ultrasonic generator is available in two models. The low frequency provides either 26/78/130 kHz or 38/100/160 kHz at up to 50 W while the high frequency model produces 200/430/950 kHz or 1.6 MHz at up to 100 W. For a complete range of low and high frequencies an installation requires either the low range generator with two multi-frequency transducers or the high range generator with four multi-frequency transducers.

The Quava Mini has an LED display for precise control of the power brought to the transducer. Power can be different in steps of 0.1 W for precise control of cleaning power. For the low-frequency model, several frequencies can be adjusted without changing the system configuration. For the high-frequency model, the transducer is changed to meet the selected frequency. A low frequency produces large cavitation bubbles for a more intense cleaning action while a high frequency produces smaller bubbles for gentler cleaning. By increasing the power delivered to the transducer more bubbles are produced at a given frequency.

What Ultrasonic Transducers Do in an Ultrasonic Cleaning System

Ultrasonic cleaning systems consist of ultrasonic transducers, cleaning tanks, and generators. The transducers are immersed in the cleaning solution and produce the cleaning action from the electric signal from the generator. When the frequency signal rises and falls, the transducers vibrate and produce compression waves in the cleaning solution. These compression waves will generate cavitation bubbles that will perform the cleaning action.

The immersion of the ultrasonic transducers into the cleaning solution can be done in two ways:

 Immersible ultrasonic transducers - These self-contained, sealed transducers that are connected to any Kaijo ultrasonic generator by a cable. They are usually placed on any existing tank which contains the cleaning solution and the object to be cleaned.

The immersible ultrasonic transducers are available at ratings of up to 1200 W and at frequencies of 26kHz, 38kHz, 78kHz, 100kHz, 130kHz, and 160kHz. Their ease of use, flexibility, and versatility make immersible transducers ideal for facilities that have a wide range of ultrasonic cleaning requirements.

Bolt-on or Mounted ultrasonic transducers - Unlike immersible transducers which are usually placed anywhere in the existing cleaning tank, the bolt-on or mounted transducers are fixed at the bottom or the side of the tank. They can also be mounted at any desired location on the tank.

They are available at ratings of up to 1200 W and at frequencies of 26kHz, 38kHz, 78kHz, 100kHz, 130kHz, 160kHz, 200kHz, 430kHz, 750kHz, and 950kHz. These transducers work well with Kaijo Quava, Phenix Legend, and Phenix III generators and they can also be installed in any ultrasonic bath or tank.

If your application calls for either fixed bolt-on or immersible transducers, Kaijo can propose a custom solution that will meet your needs. For further information read the main article on Kaijo’s website titled “What Ultrasonic Transducers Do in an Ultrasonic Cleaning System”.  

Selecting Ultrasonic Parts Cleaners for Your Industrial Cleaning Application

Ultrasonic cleaners work by producing ultrasonic acoustic waves into a cleaning solution. As the waves go into expansion phase, the low pressure yields cavitation bubbles in the liquid while the following compression phase collapses the bubbles suddenly. The bubbles act as cleaning agents that remove impurities and contamination from the surface to be cleaned. Kaijo’s ultrasonic parts cleaners produce the cleaning results that are needed quickly and cost-effectively.

Ultrasonic parts cleaners such as those using the Phenix III ultrasonic generator operates at low frequencies (26 kHz or 38 kHz) which are suitable for cleaning robust parts with stable surfaces such as ceramic, glass, medical devices, jewelry and machined parts. Systems as those based on the Phenix III generator are suitable for general cleaning in a manufacturing environment that does not deal with delicate parts or devices.

High-frequency ultrasonic cleaners are used for cleaning delicate parts such as printed circuits, semiconductor components, optical components and precision-machined parts. Such fragile parts could be easily damaged by robust bubble action found at low-frequency ultrasonic cleaners (26 kHz or 38 kHz) and require the removal of light surface contamination.

For cleaning in both high and low frequencies, Kaijo Quava ultrasonic cleaners are able to adjust varying frequencies and powers to deliver the specific cleaning intensity and power needed for certain application.

Production managers in manufacturing plants that have part cleaning requirements need to determine whether they should use a low-frequency ultrasonic cleaner for cleaning robust parts, a high-frequency ultrasonic cleaner for delicate parts, or a general purpose cleaner with both high and low frequencies. No matter their choice, Kaijo’s ultrasonic parts cleaners can cover all of their needs.

How Ultrasonic Tanks Are Used in Industrial Cleaning Applications

Industrial cleaning systems that use ultrasonic technology can clean a variety of parts and materials without the use of harsh chemicals or harsh scrubbing.

Ultrasonic tanks hold the cleaning solution and the object to be cleaned, and are mounted with traducers which produce the ultrasonic signal. Ultrasonic cleaning is especially ideal for cleaning parts like glass, ceramics, optical components, medical devices, and machined parts.

Ultrasonic cleaners generate ultrasonic acoustic waves into a cleaning solution. The ultrasonic waves generate cavitation bubbles that form and collapse at the ultrasonic frequency. The object to be cleaned is immersed in the cleaning solution inside the tank. These cavitation bubbles remove impurities and contamination from the surface of the object. Usually, it takes about 10 minutes, and even parts with complicated surface can be cleaned thoroughly.

Kaijo's ultrasonic tanks and baths are designed specifically for use in ultrasonic cleaning applications. They are resistant to ultrasonic waves and support the transducers in their cleaning action.

The tank has a stainless-steel body for excellent durability and comes in standard and customized sizes. Tanks with transducers and generators are available in 10 different frequency options. Lower frequencies produce bigger cavitation bubbles which make them suitable for robust cleaning on objects with stable surfaces. Higher frequencies produce smaller bubbles which make them ideal for gentle cleaning on delicate objects.

Kaijo’s ultrasonic baths and cleaners provide a powerful and cost-effective solution to manufacturers. They eliminate the need for harsh chemicals and the rough mechanical scrubbing required for traditional cleaning solutions.
