Zenith Manufacturing is a leading supplier of ultrasonic cleaning systems for the stamping and metal machining industries.  Since many such manufacturers stamp their product using coils of metal strip, a cleaning method was required which could clean these materials faster, safer, and with better cleaning results when compared to the traditional spray washing systems in use for these materials.  Contaminants requiring removal include stamping oils, and metallic particles.

In the past, manufacturers of stamped metallic strip materials relied on spray washing systems to address the removal of oils and particles from the product.  However, there are limitations to these designs.  If you are cleaning strip materials that may bend when subjected to a spray operation, the strip materials will be damaged.  If the strip design includes folds of metals, where oils can be trapped between 2 neighboring metal surfaces, a spray washer may not consistently clean your product.  Maintenance on a spray washer is considerable, as is water lost through evaporation.  Nozzles require constant cleaning to ensure that the spray pattern is satisfactory for successful cleaning.

A Zenith SSS-960 Ultrasonic Strip Washing System overcomes the limitations of a spray washing system by utilizing the precision, low-maintenance cleaning capabilities of ultrasonic cleaning technology.  By incorporating this technology, even the most sensitive strip materials can be processed without damage.  Removing oils from folded metal areas is easily accomplished, and the ultrasonic cleaning effect penetrates into the very surface detail itself, yielding a medical-quality cleaning result if required.  This system is perfectly suited to most progressive die stamping and leadframe stamping operations.

Strip material is passed horizontally through a series of ports and chambers in the system, and connected to optional Strip Drive Systems which pulls the material through the system at the same rate of speed as the stamping operation, allowing for convenient connection to Spool Take-up Equipment on the exit side of the cleaning system.  Loading is an easy task, thanks to the stainless steel hinged access cover which includes polycarbonate viewports.  The system can be loaded in under 1 minute.

Strip material entering the SSS-960 is first subjected to the ultrasonic cleaning chamber, which bombards the material with CROSSFIRE Multiple Frequency Ultrasonics to rapidly remove all contaminants from the surface of the strip.  The included Spray Under Submersion Nozzles add to the effectiveness of the cleaning chamber by removing the largest volumes of oils, and can be used to directly address detailed part areas.  The ultrasonic system has the ability to penetrate the microscopic "hills & valleys" on the surface of the material, leaving no residues behind, even in the most detailed areas of the strip.

Oils which are removed from the product are siphoned to the heated Cleaning Fluid Holding Tank, which stores the fluid, heating it to operating temperature, and filtering it with optional Filtration Systems, if required, to maximize the life of the cleaning fluid.

As the strip material exits the cleaning chamber, excess cleaning fluid is removed by the included stainless steel air knife assembly.  By removing the detergent from the strip before it enters the rinsing chamber, rinse water integrity is preserved which minimizes rinse water consumption, while simultaneously preventing detergent spotting on the material being cleaned.

Next, the strip material enters the included ultrasonic rinsing chamber which includes high frequency ultrasonics to penetrate every area of the material, ensuring that all detergent residues have been removed.  Optional water treatment systems, such as closed loop deionization, are available if medical quality cleaning results are required.  The use of ultrasonic components in the rinse tank provides mechanical scrubbing of the strip surface with the even energy distribution of high-frequency ultrasonics.  Additional information regarding frequencies and their effects can be found under the "technical info" drop down list under Frequency Selection.

The strip material is then using a custom air wipe assembly and a combination of 2-sided air knife assemblies which utilizes factory compressed air to completely dry the material.  The material then exits the system and is recoiled immediately using existing take-up equipment.  The final result is spot-free, medical-quality cleaning of the material without damage to the surface. 

Maintaining a Zenith ultrasonic strip washing system is simplicity itself.  the system requires only periodic cleaning and replacement of cleaning and rinsing fluids when required.  optional filtration systems will further reduce required holding tank cleaning operations, which are easily performed using the included ball valve-equipped drain and fill ports.

If medical quality cleaning results are required, deionized water will be required in the rinse tank.  deionized water which has been filtered to remove any contaminants which may leave residues on the parts after drying.  This water dries absolutely spot free, and rinse water holding tank maintenance is reduced.  However, the deionization system itself requires maintenance of its own.

With a Zenith SSS-960 cleaning system, evaporative losses are reduced drastically since water is never vaporized by spray nozzles.  As a result, operational costs are reduced since heating systems can be smaller in size.  Heating systems represent the largest electrical consumption devices on any cleaning system.

In many cases, the SSS-960 is directly connected to the stamping press.  When the stamping press turns off, the compressed air to cleaning system is also turned off, in the system may be programmed to shut down fully automatically.  If the optional Strip Drive System is purchased, this system communicates with the take-up equipment to ensure that the strip material is spooled properly.

The SSS-960 ultrasonic strip washing system is manufactured largely of type 304 stainless steel for superior long-term corrosion resistance.  All wetted surfaces are either stainless steel, or compatible plastic materials.  Smooth-transition Strip Guides are included throughout the machine to support the strip and prevent damage.  Internally-mounted components are conveniently positioned near the front of the machine.  Filtration housings are externally mounted for convenient access.  Level switches prevent operation of the heating or ultrasonic systems in the event of low liquid levels.

Optional equipment includes Automatic Water Level Maintenance, Signal Towers to indicate when holding tanks require additional liquid, Closed Loop Deionization Systems if medical-quality results are required and no deionized water supply exists, and Rinse Water Quality Meters to indicate when rinse water requires replacement.
