Keep your castings spotless with ultrasonic vapor degreasing

Porosity sealing is a critical step in parts manufacturing, porosity refers to any void or hole that forms in the metal during the casting process, a small amount of porosity is always present, in castings due to various conditions that occur as metal is injected or cooled, excess porosity can affect a parts structural integrity and make the parts more susceptible to corrosion, in parts intended to hold pressure, such as valves, pumps and compressors, porosity can also create leak paths and render the parts unusable

To protect casting integrity, a sealant is typically applied to die casings and permanent mold castings using a process called vacuum impregnation, in this process, porosity sealants impregnate the material, eliminating leak paths and weaknesses caused by microscopic voids in the material, for this sealing process to be effective, the parts must be spotless clean, any residual contaminants still present from the casing and or machining processes can compromise the seal and cause the part to fail

Why ultrasonic vapor degreasing is the most effective way to clean castings

Ultrasonic vapor degreasing is widely regarded as the preferred cleaning method for metal castings for a variety of reasons

Effective: ultrasonic vapor degreasing is highly effective at removing oil, grease and contaminants, leaving parts spotlessly clean, dry and ready for sealing.

Environmentally responsible: Vapor degreasing solvent is used over and over, so little to no chemical is released into the environment during operation, it works well with low-impact solvents, and is very energy-efficient

Cost-effective: the efficient use of solvent and energy, along with the speed and simplicity of the procedure, helps keep operation and labor costs contained

Space-efficient: Because of ultrasonic vapor degreasing does not require separate chambers for cleaning and drying, the equipment takes little space in the working shop, that is to say all of functional process in one machine

Easy: the ultrasonic vapor degreasing process is simple, requiring minimal labor and training

How Does ultrasonic degreasing work?

In ultrasonic vapor degreasing, solvent is boiled in a sump to create a vapor, which is contained in the unit by means of chilling coils at the top, this cold area forms a bold barrier that causes the solvent to return to liquid form and precipitate back into the sump, as parts are lowered in the vapor layer, solvent condenses on them and runs off, carrying oil and contaminants with it

After a few minutes in the vapor atmosphere, the parts can also be lowered in the liquid layer of the samp bath for additional cleaning effect, at the end of the cleaning cycle, the parts are lifted back out of the vapor bath, as they pass through the cold layer, the solvent quickly evaporates, leaving the parts clean and dry.

Where exceptional cleanliness is required, parts may be subjected to final cleaning cycle, a dip into an adjacent rinse sump filled with solvent, spray cleaning with additional solvent or ultrasonic agitation cleaning, this ensures that any remaining contaminants are thoroughly removed in preparation for the sealing process

Effective and Budget-friendly casting cleanliness

While there are other casting cleaning methods available, most parts manufacturers prefer ultrasonic vapor degreasing for its significant benefits over the alternatives, for example, aqueous cleaning systems tent to be slower, more complex and more expensive to operates

Ultrasonic vapor degreasing also accomplishes cleaning with little to no risk of abrading or damaging parts, if you are looking for a proven effective way to keep you casings clean and ensure high quality results, give ultrasonic vapor degreasing a try
