Ultrasonic cleaning technology is widely used in the die-casting industry, its main function is to clean the die-casting parts, remove surface dirt and residues, and improve the quality and production efficiency of die-casting parts. This article will introduce the application of ultrasonic cleaning machines in the die casting industry and how to clean die castings.
1、 Application of Ultrasonic Cleaning Machine in Die Casting Industry
The application of ultrasonic cleaning machines in the die-casting industry mainly focuses on the following aspects:
1. Cleaning of die-casting molds
Die casting molds are key equipment for producing die castings, and their surfaces are easily affected by pollutants such as oil and dust. The use of ultrasonic cleaning machines can quickly and thoroughly clean die-casting molds, improving production efficiency and product quality.
2. Surface cleaning of die-casting parts
The surface of die-casting parts often contains residual pollutants such as oil stains, oxide scales, and metal chips. The use of ultrasonic cleaning machines can effectively clean the surface of die-casting parts and improve product quality.
3. Removal of air holes in die-casting parts
During the production process of die-casting parts, defects such as pores and holes often occur, which can affect the quality and performance of the product. The use of ultrasonic cleaning machines can remove pores and holes in die castings, improving product quality.
2、 How to Clean Die Castings
The following points should be noted when using an ultrasonic cleaning machine to clean die castings:
1. Selection of cleaning solution
When cleaning die castings, it is necessary to choose an appropriate cleaning solution. The type and ratio of cleaning solution should be selected based on the material and surface treatment method of the die casting. The commonly used cleaning fluids include acidic cleaning fluids, alkaline cleaning fluids, organic solvent cleaning fluids, etc.
2. Cleaning time and temperature
The selection of cleaning time and temperature is also very important. Normally, the cleaning time should be long enough to ensure thorough cleaning of dirt and residue on the surface of the die casting. The selection of cleaning temperature should take into account the characteristics of the cleaning solution and the material of the die casting, to avoid problems such as oxidation or deformation of the surface of the die casting caused by high or low temperatures.
When cleaning die castings with an ultrasonic cleaning machine, it is necessary to choose the appropriate ultrasonic power and frequency based on the material and shape of the die castings. Normally, the higher the ultrasonic power and frequency, the better the cleaning effect, but excessive power and frequency may cause damage to the die casting.
3. Operation of the cleaning machine
When using an ultrasonic cleaning machine to clean die castings, it is necessary to pay attention to the following operational details:
(1) Firstly, clean the surface of the die casting to remove large particles of dirt and residue;
(2) Place the die-casting parts into the cleaning tank and pour the cleaning solution into the cleaning tank;
(3) Start the ultrasonic cleaning machine, adjust the ultrasonic power and frequency, and start cleaning;
(4) The cleaning time is generally between 10-20 minutes, and can be adjusted according to the actual situation;
(5) After cleaning, remove the die-casting parts and rinse them with clean water to remove any residue of the cleaning solution;
(6) Finally, air dry the die castings or blow dry them with a fan.
In summary, ultrasonic cleaning machines are widely used in the die casting industry, as they can effectively clean die castings, remove surface dirt and residues, and improve product quality and production efficiency. When using an ultrasonic cleaning machine to clean die castings, it is necessary to pay attention to the selection of cleaning solution, cleaning time and temperature, ultrasonic power and frequency, as well as the operating details of the cleaning machine.
