Ours is a business with a great reputation for offering specialist tubing manipulation services. This includes tube swaging in addition to a number of others. We swage tubes to alter the interior diameter while keeping the exterior the same. With skills like these, we are able to supply tube that can help you create all sorts of products.

The story behind small diameter metal tubing

These tubes are very common in medical and precision applications. Manufacturers can produce them in a myriad of sizes. For example, one could be a 3/8 inch outside diameter and another might be a hypodermic needle gauge.

During the manufacturing, it is common for the tubes to pick up contaminants. The trouble here is they can be hard to remove, especially as the interior diameters decrease. Tube swaging may make it harder as well, especially if the inner diameter is angular. With an ultrasonic cleaner however, you have major advantages when you attempt to get rid of them.

You perform contaminant removal by using cavitation action within an ultrasonic cleaning solution. This action is where you implode tiny bubbles. You do so against the exterior of those components you are cleaning. It scrubs away the contaminants in a safe manner. Said contaminants can include metal fines, lubricants, and drawing compounds.

The right frequency

For everything to work though, you must select the correct ultrasonic frequency. The thing about cavitation is that it uses ultrasonic transducers. These bond to cleaning tanks made of stainless steel. The majority of utensils will function at certain frequencies. Standard ones are 25, 37, 45, 80, and 130 kHz.

Something to remember

There is something important that you need to remember here. The greater your ultrasonic frequency, the more compact the cavitation bubbles will be. In addition, the scrubbing action shall become gentler as well. For instance, somewhat big 25 kHz cavitation bubbles cleanse huge cast metal or fabricated components before finishing or extra processing.

As finishes become increasingly refined and parts get more complex, people use higher frequencies for two reasons. For one thing, they are not as likely to produce surface damage on highly finished components. Secondly, they penetrate blind holes, crevices, and cracks more easily.

Temperatures

Another performance element of ultrasonic cleaning is the temperature. With pure water, cavitation action improves as temperatures go up. This happens to about 70°C. After this efficiency decreases and halts entirely at the boiling point.

As for the ideal temperature, this depends on the solution’s properties. Ultrasonic cavitation increases the temperature. While this occurs, cleaners can have more control when they have thermostats and heaters.
