Milling and cutting

The smallest particles or thinnest layer of film residue can have a negative impact on the performance of today’s manufactured components. Compromised parts can impair the quality and functionality of finished goods to the extent that costly rework and delays are required.

Considering the demands of compliance regulations and lean manufacturing best practices, the pressure to produce flawless manufactured parts has never been greater. Cleaning is a critical part of the process, and it needs to be accomplished in a way that does not delay or inhibit production. This can present a serious challenge for manufacturers in a wide range of industries.

Cleaning Technologies Group is the industry leader in parts cleaning equipment and dedicated to delivering practical and effective solutions for a wide range of general manufacturing applications. Through our Blackstone-NEY Ultrasonics division we offer ultrasonic cleaning equipment for efficient precision cleaning that is environmentally safe and able to meet the demands of challenging parts cleaning applications.

Introducing the perfect washer for high volume cleaning applications

RBS Modular System

The RBS Modular System is an automated immersion cleaning system that can be expanded as needed to meet your process requirements. The RBS Modular System is a dedicated inline process that includes a Wash, Rinse, Ultrasonic Wash, Ultrasonic Rinse, Heated Blow Off and a final Vacuum Drying System. This system is set up to process parts in a basket or on a fixture. The RBS Modular System can handle parts up to 1100 LBS (500kg) and can do up to 15 cycles per hour.

The RBS Modular System cleans using a washing and rinsing process of agitation, spray impingement, hydraulic purging through immersion and rotation, ultrasonics, and heated blow-off drying. The "triple action" batch cleaning process was developed specifically to process a broad range of challenging parts, especially those with internal bores and passages and complex geometries, making this system capable of meeting critical cleaning expectations.

CNC Cleaning Machinery

Ultrasonic cleaning is a proven method for the safe and effective removal of contaminants from optical components and assemblies. The compounds are used to polish mating surfaces to a perfectly smooth flat surface. In these applications it is absolutely critical that complete cleaning is accomplished while also avoiding scratching or otherwise compromising the product.

The sensitive components used in laser and optic applications must be precision cleaned to provide optimal performance. When contaminants such as smoke or resin accumulate on parts, available power to the equipment is reduced, and may result in damage. Anything less than entirely clean optics can also significantly reduce engraving and cutting quality.

Blackstone-NEY Ultrasonics offers a host of cleaning technologies that meet the unique requirements involved with the cleaning of optics, flat panel, and laser components. Our team has developed customized solutions for glass and quartz etching, rinsing, LCD display grade glass, prisms, polycarbonate and ophthalmic lens, laser and fiber optics, aluminum device housings, and more.

Berrings with plated surfacing

Surface treatment applications require a clean substrate that is entirely free of contaminants. Not only does this help to provide a lasting metal finish, it also promotes product uniformity.

Ultrasonics Are Effective For Many Surface Treatments

Proper cleaning and rinsing promote the best results in plating and surface finishing processes such as:

  • Electroplating
  • Anodizing
  • Pickling
  • Passivation
  • Etching
  • Stripping

Ultrasonic cleaning uses the power of high-frequency sound for the complete and efficient removal of contaminants. Ultrasonic cleaning has proven very effective in ensuring that part surfaces are absolutely clean, due in part to the ability of ultrasonics to thoroughly clean the complete wetted surface area, including blind holes and crevices. Cavitation is the key to the effectiveness of ultrasonic cleaning, providing the power to blast dirt from surfaces. It has the added benefit of reaching every wetted surface of the object to be cleaned, including intricate crevices.

MD&M West 2022

Blackstone-NEY Ultrasonics, a world leader in providing cleaning and waste minimization technologies, will introduce a host of advanced cleaning solutions at the MD&M West 2022 in Anaheim, California April 12 – 14, 2022. Visitors to Blackstone-NEY Ultrasonics Booth #1459 will be introduced to several new products, technologies, and services. Among the new technologies exhibited at the show will be:

Aquarius: Combining ultrasonic cleaning with rinsing, drying and other processing steps in a unitized cleaning console helps assure process integrity. The addition of an automated, robotic transfer, environmental enclosure, and DI water systems increases cleanliness levels and provides process consistency while significantly reducing the labor required for parts cleaning.

Aquarius Series Multi-Tank Ultrasonic Cleaning Systems are pre-engineered to meet a wide range of parts cleaning needs at an attractive price. This platform can also be featured to handle your nitric or citric acid passivation requirements.

HT- IPA: A perfected ultrasonic cleaning tank for use with Class 1, Div. 1 Group D, T4 solvents. The HT-IPA is designed for small parts cleaning applications in which a flammable solvent is required. The HT IPA is currently available in two sizes that are independently certified by ETL (Electronics Testing Laboratories).

Megan Lovitt Portrait

Megan Lovitt has joined CTG as the Director of Human Resources effective November 2021. Megan will serve as a member of the executive management team, overseeing all aspects of human resources including management, compensation, employee benefits, and training.

“Megan brings many years of Human Resources experience to CTG and we are excited to welcome her. She will be a strong contributor to the executive team" said our CEO, Barney Bosse.

Cleaning methods are as varied as the types of surfaces, substrates, and particles that exist. Not only is it important to consider all of these factors, it is necessary to think about how particles not only adhere to substrates, but also interact with and attach to each other. This is why there is no one-size-fits-all type of cleaning approach that works for every application.

The Mechanics of Cleaning

The mechanics of cleaning involve the removal of either soluble or insoluble contaminants, or a combination of both. Ultrasonic cleaning is the preferred method for the removal of soluble contaminants and particles that are less than approximately 6mm in size.

Robotic Handling and Automation eBook cover

In today’s manufacturing world, a wide range of businesses are increasing efficiency and improving production with robotic parts washing and other customized automated washing solutions. Automated washing systems offer the added benefit of improving product quality and consistency, while freeing valuable human labor resources for other tasks.
