Why Industrial Cleaners Are Used by Plastic Manufacturers

Manufacturers of plastic products need to clean their equipment between production runs. They also often need to clean the plastic products they manufacture as well.

Also, manufacturing plastic products have various cleanliness standards, depending on the end use of these products. For instance, products that are meant for use in food and medicine must have more stringent cleanliness requirements. Other plastic products used in industry applications may require less strict levels of cleanliness.

More plastic product manufacturers have turned to industrial ultrasonic cleaners from the old traditional cleaning methods that require intense mechanical scrubbing and the use of harsh chemicals.

High performance industrial ultrasonic cleaners can deliver different levels of cleaning action by choosing the right frequency and power. The microscopic cleaning bubbles produced by Ultrasonic cleaners penetrate wherever there is cleaning liquid in the cleaning tank. These bubbles completely and effectively remove contaminants down to the plastic base or tool material.

The benefits that industrial ultrasonic cleaners provide to plastic manufacturers include the following:

• Reduced costs due to the absence of harsh cleaning chemicals;
• Reduced labor costs because there's no more manual scrubbing, scraping, or pressure washing;
• Increased worker safety because the ultrasonic cleaning process is safe and needs little human supervision;
• Less time spent on cleaning because the ultrasonic cleaner's quick one-step cleaning process;
• Superior cleaning performance as the ultrasonic bubbles penetrate holes and crevices of the surfaces being cleaned;
• Longer tool and mold life because ultrasonic cleaning does not cause damage to the molds and tools;
• Better output quality because the ultrasonic cleaning parameters can be selected to specific cleaning application requirements by using appropriate frequencies and power levels.

How to Buy the Right Ultrasonic Cleaner for Your Application – Part 2

The most important things to consider in choosing an ultrasonic cleaning system are the size of the tank, the frequency of the system and the power it can provide. Aside from these the accessories such as a tank temperature heater and holding basket should also be considered when choosing the right system for a cleaning application.

Cleaning tank heater:

Ultrasonic cleaners work by generating tiny cavitation bubbles which clean and scrub surfaces of parts to remove contamination. However, when contaminants on surfaces are hard deposits that are difficult to clean, the cleaning action of the bubbles will take more time. In these cases using a heating, the liquid in the cleaning tank will help to soften or loosen the hardened contamination from the surfaces being cleaned. That's where the cleaning tank heater enters the picture.

While cleaning tank heaters are a useful option for ultrasonic cleaning systems, they should be designed for the application. Untreated plain water (below 100 degrees centigrade) may be used most of the time but mild cleaning solutions can also be used. If the cleaning solution is considered, the heat settings should be controlled so that solution won't start boiling. The ultrasonic transducer should also be designed in a way that it will be able to withstand high temperatures.

Using sweep frequencies:
Kaijo’s ultrasonic cleaning systems operate at certain frequencies and are designed to achieve the optimum cleaning results according to the size of the cavitation bubbles and their cleaning intensity. However, a system may experience some unpredictable negative effects. This results in the ultrasonic waves canceling each other and no cleaning occurs. Using sweep frequencies will reduce this effect.

Water resonance system

The water resonance system helps ensure even cleaning action throughout the tank. The water treatment of a water resonance system provides an even distribution of nuclei essential for bubble formation. This allows bubbles to form everywhere within the cleaning solution rather than mostly above the ultrasonic transducer. This provides an even cleaning action on everything placed in the cleaning tank.
