Injection Mold Life Extended with Ultrasonic Cleaning

Before and After Ultrasonic Cleaning Injection Molds

Injection molds used to form plastic products can represent sizeable investments and are characterized by complex shapes, precision finishes and vents.  Cleaning plastic injection molds must be accomplished on a regular basis and in such a way that removes all traces of burned on deposits from surfaces and residual plastic in vents without scratching or otherwise mechanically damaging mold surfaces.   

“Our investment in injection molds can reach tens of thousands of dollars each,” says Roger Wheeler, tooling manager at PAM Injection Molding based in Kernersville, NC. “While different molds have different surface tolerances, customer-demanded tolerances for a mold surface can be as precise as 0.0002 inch. That’s why,” he says, “longer injection mold life depends highly on not only keeping them clean but conducting mold cleaning operations in such a way that extends their life by maintaining surface finish tolerances.”… Read the rest

Ultrasonic Cleaners for Jet Engine Maintenance

Ultrasonic Cleaners for Jet Engine Maintenance

Regular maintenance procedures are strictly prescribed for aircraft jet engines and include thorough cleaning and inspection of fuel nozzle assemblies.  “An example is the highly popular Pratt & Whitney PT6A engine which requires cleaning engine fuel nozzle manifold adapter assemblies every 400 hours of operation,” says Scott Pottebaum, Director of Technical Services, Elliott Aviation in Des Moines, IA.   “Overhaul and maintenance procedures are clearly spelled out in the P&W Maintenance Manual; service organizations such as Elliott Aviation are responsible for performing these procedures then testing the engines before they are approved for return to service.”… Read the rest

Ultrasonic Cleaning of Scuba Gear

Ultrasonic Cleaners for Scuba Gear Maintenance

Perfectly functioning valves and regulators are essential for reliable air supply to scuba diving enthusiasts. Fresh water rinsing scuba regulators after each dive is part of the ritual; ultrasonic cleaning of disassembled regulator components should be a part of any organization renting gear or offering scuba diving excursions.

A good example is Florida based All Star Liveaboards, offering scuba diving enthusiasts “the best in liveaboard scuba diving and snorkeling in the Caribbean.”  Living aboard the Aqua Cat or other company vessels participants enjoy  week long cruises  from Nassau, Bahamas, to the islands of the Exuma Sound.  Participants include experienced divers with their own or All Star’s rental gear and novices wishing to learn the sport from All Star’s certified on-board scuba instructors.… Read the rest

Ultrasonic Cleaners for Flammable Solvents

ultrasonic cleaning using flammable solvent

Ultrasonic cleaners are widely recognized as providing outstanding cleaning action thanks to the cavitation produced by the equipment’s generator powered ultrasonic transducers.  But when cleaning with flammable solvents it is imperative that explosion resistant ultrasonic cleaners are employed in the shop, and that the equipment be located in an area equipped with an adequate exhaust system to vent fumes to an exterior location.

Flammable solvents are often preferred for tough cleaning jobs such as degreasing and removing tenacious contaminants like paint and adhesive residues.  Special care must be exercised when cleaning with flammable solvents under any circumstance, but especially when using an ultrasonic cleaner to both speed the process and improve cleaning results.   Unless they are specially constructed, ultrasonic cleaners present two risks:  sparks from internal electronics igniting spilled solvents and fumes, and vapors from solvent evaporation creating a hazardous area in the vicinity of the unit.   … Read the rest

Ultrasonic Cleaning Preserves New and Old Vinyl Records

Ultrasonic Cleaning of Vinyl RecordsVinyl records, the 33-1/3 RPM LPs and 45 RPM (juke box) discs, first came on the market in 1948 and in the 1950s grew tremendously in popularity until the advent of CD recordings.  But then something strange happened. Sparked by music aficionados’ appreciation of the unique sound quality of vinyl vs. digital CDs and the ability of ultrasonic cleaning to preserve and restore these records, vinyl sales increased 32% to $416 million in 2015, a 28-year high according to the Recording Industry Association of America.

The resurgence of interest in vinyl recordings has led to a new service industry specializing in cleaning the discs to preserve their unique sound quality and minimize wear.  A leader in this service is Pure-Grooves, LLC based in the Chicago suburb of Berwyn, IL.  Company founder Vince Tornabene has developed a  vinyl record restoration service based on a dual-frequency, adjustable power Elma P60H ultrasonic cleaner … Read the rest

Guidelines to Selecting Ultrasonic Cleaning Solutions

Ultrasonic cleaning is widely accepted in pharmaceutical, healthcare, electronics, medical device manufacturing, and related industries where product cleanliness is critical during and following production cycles. Powerful but gentle scrubbing action of imploding cavitation bubbles in ultrasonic cleaners is unsurpassed in removing the most tenacious of contaminants. The availability of biodegradable water-based ultrasonic cleaning formulations both broadens the application of sonic cleaning energy and removes disposal concerns associated with earlier used formulations such as trichloroethylene and perchlorethylene.

Correct cleaning solution formulations, along with applicable pre- and post-cleaning procedures, are an important part of compliance with QC and QA standards.  Tovatech’s Bob Sandor writes about this in  the February 1, 2017, issue of Controlled Environments.Read the rest

How to Pick the Best Ultrasonic Cleaner

Selecting the Best Ultrasonic Cleaner

Among the steps to be taken to pick the best ultrasonic cleaner is a thorough understanding of what the process is to accomplish and then identify ultrasonic cleaner features that let you accomplish the task(s) in the most cost-effective way.  While ultrasonic cleaners are available from a variety of manufacturers and across a broad spectrum of prices, your investment must be based on an assurance that it will accomplish your task(s) quickly and efficiently.  When you do this you’ll be able to identify your best ultrasonic cleaner.

In other words, pick the ultrasonic cleaner you need.  Don’t succumb to “keeping up with the Joneses.”

An Important Ultrasonic Cleaner Priority:  Size

You can’t mount a 19-inch tire on a 15-inch wheel.  Similarly the dimensions (length, width, depth) of the ultrasonic cleaner’s tank must be sufficient to accommodate the largest component you plan to clean.  But there’s more:  Because a majority of … Read the rest

How to Maintain Firearms with an Ultrasonic Cleaner

5 Steps for Maintaining Firearms with an Ultrasonic Cleaner

Investments in firearms, be it by collectors of antique guns, law enforcement agencies, operators of gun shooting ranges, hunters or shooting enthusiasts of any stripe, can be substantial.  Planning to maintain firearms is an important part of protecting your investment in pistols, rifles and similar weapons. Ultrasonic cleaners are widely employed by gun shop repair services, law enforcement agencies, the military and gun clubs, and for good reason.  Nothing is better when it comes to removing lead shavings, residues from powders, old lubricants, in fact any contaminant that causes wear or otherwise impacts the performance or degrades the value of the firearm.

Several ultrasonic cleaner options are available to gun owners, whether individuals, a club or public safety organization. But before getting into examples of what to look for we’ll start with a description of why the ultrasonic gun cleaning process is so effective when compared to manually cleaning and … Read the rest
