Customized Ultrasonic Cleaner for Injection Mold Equipment Cleaning with Rinsing Drying Tank

Cleaning dies and moulds is labour intensive and also often abrasive.

By using ultrasonic for mould

maintenance, the result is a cleaner mould with reduced manual input and no wear leading to large cost savings, extended mould life, and shorter payback time. The technique suits plastic, rubber and die cast moulds and tools.

Ultrasonic cleaning uses high-frequency sound waves to remove mould residues and fouling from tooling and plates that are immersed in a heated (usually 80 degree C) aqueous solution. An ultrasonic generator converts standard line-frequency current (60 or 50 Hz) into high-frequency electrical energy (20,000 Hz or more). The generator is connected to small transducers that are mounted to the bottom or sides of a wash tank. These transducers vibrate at ultrasonic frequencies (20 kHz and above) when the current passes through. This causes the bottom or sides of the tank to vibrate like the diaphragm in a speaker, which creates microscopic bubbles that form and collapse in the tank (a phenomenon known as cavitation), which scrub and loosen vent residues and grime. The energy released from these microscopic scrubbing bubbles produces forces at 10,000 degree F at 7500 psi, which is powerful enough to loosen contaminants without damaging critical edges or surface finishes.

Ultrasonic cleaning gives the following advantages:

1. Short wash process leading to reduced time spent in cleaning

2. No manual labour required. An operator is not required when the machine is cleaning the mould

3. High levels of cleanliness give longer life in production

4. No abrasion of precise edges and surfaces gives longer mould life

5. No solvents needed because of aqueous process

6. Suitable for all moulds, large and small

7. Machinery is simple and easy to use

Specifications:

Features:

1st tank is ultrasonic tank with oil filtration system: remove contaminants from the product.

2nd tank is rinsing stage, remove residues detergent

3rd is Drying stage, remove rinse water

Although the 3main tanks are the same, the ultrasonic cleaner must be properly configured with additional equipment to clean these items successfully.
