Selecting the cleaning equipment is governed to a large extent by the size of molds being cleaned. Ultrasonic cleaners are available ranging from small benchtop units to industrial-sized floor-mounted equipment that can be fitted for automated cleaning and rinsing cycles. But do select a cleaner with a heater, timer and sweep mode.

The process is fairly straightforward regardless of equipment size. Here’s a simplified description that can be modified based on your specific operations:

1. Fill the ultrasonic cleaner with water but allow room for cleaning solution displacement due to the size of the molds being cleaned. Add the proper amount of biodegradable cleaning solution concentrate. Ask the scientists at Tovatech to recommend the correct formulation based on the type of contaminants you are removing and what the mold itself is made of.
2. When you are ready to clean place the injection molds in the cleaner basket. Take care that they do not contact each other. If you are cleaning large parts you may suspend them in the cleaning solution so they do not contact the tank bottom. Some industrial cleaners are equipped with bottom racks to support products being cleaned.
3. Set the heater to 65 C and timer from 10 to 60 minutes depending on the degree of contamination. Activate the sweep mode to assure uniform distribution of cavitation and promote uniform cleaning then lower the molds into the solution. With experience you will establish optimum cleaning conditions.
4. At the end of the cycle remove the molds and inspect. When satisfied, rinse them with fresh hot water and allow them to dry or blow them dry with compressed air. Note that intricate configurations and cavities may trap water that should be removed by adding an electric drying oven to your setup.

Rinsing tip: You’ll want to thoroughly remove cleaning solution residues. Complex shapes may call for a spray rinse or, in certain cases, rinsing by cavitation in an ultrasonic rinse tank.

How to Clean Large Plastic Injection Molds

Complex molds require careful cleaning.

Complex injection molds represent substantial investments by plastic injection molding companies which, in order to protect their investments, must establish cleaning procedures to remove a variety of stubborn contaminants. These include burned on residues, oils, flashing and grease that if allowed to remain will result in product rejection by the quality control department. Hand scrubbing with solvents simply does not do the job. In addition to being time consuming, manual cleaning introduces potential health hazards for personnel and solvent disposal challenges. The solution is using an ultrasonic cleaner instead of scrubbing in a solvent-based parts washer.

Why an Ultrasonic Cleaner is Ideal for Injection Molding

In three words: thorough, safe and fast. Contaminants missed by manual cleaning are usually those deep in crevices and on other surfaces impossible to reach. Moreover, highly finished mold surfaces can be scratched or otherwise damaged by manual processes. Large molds can be difficult to maneuver, further risking damage during manual cleaning. And the longer it takes to clean the molds the greater the risk of damage.

Ultrasonic cleaning action solves all three issues.

It is thorough because it reaches all mold surfaces immersed in a biodegradable water-based ultrasonic cleaning solution. It is safe because while the cleaning action can be termed “violent” it occurs so fast that highly polished injection mold surfaces are not damaged during the cleaning process. By fast we mean 10 to 15 minutes although large complex molds may require a longer cleaning cycle.

Plastic Mold Cleaning by Cavitation Action

Cavitation action is described as the implosion of countless minute bubbles against surfaces of products immersed in the cleaning solution. Bubbles are created when generator-powered transducers bonded to the ultrasonic cleaner tank vibrate at ultrasonic frequencies measured in thousands of cycles per second or kilohertz (kHz).

Large Ultrasonic Cleaners

AGSONIC Ultrasonics manufactures large ultrasonic cleaners for the cleaning of heavy and big components with light or heavy contamination. Large tanks are usually required to clean parts such as:
Plastic Injection Molds
Aerospace components
Large batches of smaller parts
Bulk rebuilding of firearms
Heat Exchangers
Engine blocks

Q. "How do I dispose of the waste fluids generated by the ultrasonic cleaner?"

A. In the case of a smaller manufacturer, the cleaning fluids can be collected and disposed of as oily detergent waste. However, many AGSONIC customers are successfully using Wastewater Evaporators to eliminate the waste which is generated by the ultrasonic cleaner. Since ultrasonic cleaning fluid is typically 95% water, this portion of the waste is evaporated. The 5% balance of the waste collects as a sludge in a collection tank which is later disposed of by traditional means. AGSONIC can supply wastewater evaporators to drastically reduce the amount of waste material which requires disposal.

What do I need to consider when purchasing a large ultrasonic cleaner?

When dealing with large liquid volumes and ultrasonic cleaners, there are several considerations:
Tank Integrity: The tank needs to be able to withstand the pressure of the liquids and the weight of the parts being cleaned. This requires a specific tank design that moves the stress points away from welded edges.
Ultrasonic Power: There needs to be enough ultrasonic power to provide the cleaning performance you need.
Ultrasonic Frequency: The frequency chosen will usually be in the low frequency range when cleaning heavy parts, or AGSONIC's patentedCROSSFIREMultiple Frequency Ultrasonic System operating at 25 and 40kHz.
Heating Systems: Large tanks may require extended time to heat to operational temperatures due to the large liquid volume in the tank.
Filtration Systems: Need to be large enough to remove the dirt being removed from the parts, and push to dirt towards to filter system suction port. Filter housings and pumps need to be larger.
High-volume Oil Skimming: When removing greases and oils, a high volume oil skimmer with the ability to isolate surface oils from the cleaning tank is needed to prevent oils from re-depositing onto parts when they are removed.
