1911 Firearm

To assure safe and proper functioning, firearms components must be cleaned to the highest standards. Critical cleaning for firearms and parts must provide thorough precision cleaning of all component surfaces, inside and out. As a leader in parts cleaning equipment and ultrasonic cleaning technology, we offer a number of reliable cleaning technologies for small, precision firearm components and projectile components.

Firearms Parts Cleaning Equipment

The Ransohoff Lean Jet RB series immersion cleaning systems provide thorough and effective cleaning using our triple action parts washing and rinsing process of agitation, spray impingement, rotation, hydraulic purging through immersion, and heated blow-off drying.

These rotary basket immersion cleaning systems are designed to fit into your work cell area or a smaller production environment.

Ultrasonic Firearm Component Cleaning

Blackstone-NEY Ultrasonics is a leading supplier of precision ultrasonic cleaning equipment for firearm parts for gun manufacturers, gun shops, law enforcement, and the military. Our ultrasonic cleaning technology is also well suited for cleaning suppressors and silencers since they can be cleaned without disassembly, and at optimum frequencies to minimize erosion.

Blackstone-NEY Ultrasonic precision cleaning solutions that are ideal for firearm applications include:

CTG serves fastener manufacturers with a variety of Ransohoff cleaning solutions, which are well suited to meeting the rigorous requirements of fastener parts cleaning. Our cleaning systems assure fastener manufacturers the highest quality cleaning to meet the toughest challenges and most rigorous standards.

Drum Washers for Fasteners Cleaning

Fastening cleaned nuts and bolts

Ransohoff standard drum washers use both spray and immersion technology. Thorough, but gentle cleaning removes all contaminants from part contours and surfaces. For inline processes, drum/auger washers are typically the machine of choice for headed parts. This is due to their ability to wash large volumes of parts per hour. They can also be placed at the end of a press for continuous flow.

Drum washer advantages include:

  • High throughput
  • Inline with header machine
  • Simple/reliable operation

Rotary Basket Parts Washers for Fasteners Cleaning

Ransohoff rotary basket parts washers have been developed to fit in a work cell area or a smaller production environment. The Lean-Jet RB series of immersion cleaning systems cleans uses our patented washing and rinsing process of agitation, spray impingement, rotation, hydraulic purging through immersion, and heated blow-off drying.

Medical device cleaning presents a unique set of challenges. Extremely rigorous cleaning standards are maintained for instruments used in surgery, medical and dental procedures, as well as devices used as medical implants. While these devices often have difficult to clean features like blind-holes and designed-in porosity, they also have the most stringent requirements for disinfection and sterilization.

The conventional approach to sterilization of medical devices has been the use of high-pressure steam or vaporized hydrogen peroxide (VHP). When medical devices are inadequately cleaned however, residual soil can effectively seal in contamination, actually preventing proper disinfection and sterilization. Thus, a capable and robust precision cleaning process is the pre-requisite for sterile device manufacturing.

The unique characteristics of ultrasonic cleaning make this automated cleaning method ideal for medical device cleaning. The ultrasonic cleaning process has been demonstrated to be more effective than other types of cleaning, and is also safer, more repeatable, and more efficient than manual cleaning. Ultrasonic cleaning systems easily and thoroughly remove a wide range of debris from medical devices without damaging the part substrate.

When looking for an alternative to environmentally harmful parts cleaning solvents, manufacturers have turned to aqueous parts cleaning methods, including ultrasonic parts cleaning. In this post we’ll provide an overview of both aqueous parts cleaning and ultrasonic parts cleaning, and what to consider when choosing a parts cleaning method.

What is Aqueous Parts Cleaning?

Aqueous parts washers offer the cleansing power of solvent-based parts washing but uses water as its primary cleaning agent. Solvents can be used with the water in aqueous cleaning, depending on the parts cleaning requirements. These may include things such as emulsifiers, Inhibitors, anti-foaming agents, PH buffers, and more.

The determination of the most effective aqueous parts cleaning approach for a given application begins with the following questions:

  • What parts are being cleaned?
  • How detailed are the parts?
  • What materials are involved?
  • What is the production time allowance?
  • What are the customer requirements?

From there, the best equipment technology can be selected. Methods of aqueous cleaning can involve immersion or soaking, standard and high pressure spraying, or ultrasonics.
