If you polled gun owners, you would probably find that most say one of the most tedious parts of owning a gun is cleaning it. The traditional way involves messy and smelly chemicals and oils, taking apart the weapon, and painstaking scrubbing at each individual part and the inside of the barrel with wire brushes.

3D Printing is one of today’s hottest technologies, enabling anyone from engineers to enthusiasts to create intricate plastic models of just about anything that can be designed by a computer. 3D Printing consists of two types of thermoplastics: ABS and PLA. ABS is a more durable plastic used for the object mold itself, and PLA is used as a mold support, supporting the ABS plastic until it dries. The PLA plastic is then removed to produce the final “printed” object. [Read more…]
You’ve been thinking about, or have already purchased, a brand new ultrasonic cleaner from Omegasonics. You are getting ready to set your first batch of parts to be cleaned, and you realize you just aren’t sure how you should be putting the parts into your cleaner—or maybe you are an old hat, and you want to make sure you are getting the most out of your unit. Don’t worry; it is a common question. The short answer is yes, there are some tricks to ensuring that your parts come away as clean as possible and undamaged. Read on to find out the proper techniques for an ultrasonic parts cleaning.
Are you looking to get your dentures as clean as they possibly can be? Brushing and soaking are only so effective. They can’t really dislodge everything that gets collected on your dentures down to a microscopic or microorganism level. Dentist offices have a device called an ultrasonic cleaner that they use for getting their instruments and dentures clean. The good news is that you too can have one of these units to do your own ultrasonic cleaning for dentures!

Are you working with very small or fine parts that need to be cleaned? Are you still cleaning those parts by hand? Why not consider switching to an Omegasonics ultrasonic cleaning system? Not only will the time it takes to get your cleaning jobs done be dramatically reduced, but you can also increase the precision of the cleaning action of your ultrasonic cleaner by increasing the frequency of the oscillator!
The Principal behind Ultrasonic Cleaners
If you are not familiar with the principals of operation of an ultrasonic cleaner, you may be wondering to what frequency is being referred.
Ultrasonic cleaners operate by using sound waves to do the cleaning. A small device called a piezoelectric oscillator creates sonic waves in a cleaning fluid. To best visualize this, picture dropping a rock into a lake. Where the rock impacts, you can see the ripples pushing out over the surface. The peaks and dips in the waves are what create the cleaning action.
The vibration of the oscillator in the solution causes very small bubbles. The bubbles carry a high amount of energy with them. When the bubbles collide with the part you are cleaning, they release that energy. Anything that isn’t supposed to be attached to your part will be slowly broken up and carried away by the bubbles. This process is called cavitation.
Where Does Frequency Fit In?
Let’s go back to our analogy of the rock in the lake. Dropping one rock into the lake will cause a series of ripples that will eventually disappear. What happens if you drop a second rock into that exact spot? More ripples. Imagine being able to time it so that you could drop a rock in the water with enough precision to just keep the ripples moving across the surface. Now, what happens if you drop rocks in faster?
Dropping them in faster will impart more energy into the fluid and causing the space between the ripples to shrink. This is exactly what happens in your ultrasonic cleaner. As you increase the frequency of the osculation, the bubbles that are created in the cleaning solution get smaller and smaller.
How Does This Increase Precision?
If you are cleaning something like tubing or a hypodermic needle, you may be in need of making sure that a very small orifice is opened. This means that smaller bubbles will be able to carry more energy to the small places you really to clean for your precision cleaning application.
This can be extremely helpful in the electronics industry. Being able to clean up very small solder drops or break free potentially damaging traces that are invisible to the naked eye can all be achieved just by having your cleaner at a higher frequency!
