Cleaning of Metal Parts

Cleaning of metal parts is an essential process in many industrial sectors, from manufacturing and automotive to medicine and electronics. Ensuring that parts are free of contaminants such as oils, grease, oxides and production residues is essential to guarantee their optimal performance and prolong their useful life.

In this context, ultrasonic cleaning has established itself as the best alternative to traditional methods, as it allows for deep cleaning without damaging surfaces or altering the properties of the material.
 

Cleaning of Metal Parts with Ultrasonic Machines

How does ultrasonic cleaning of metal parts work?
Ultrasonic cleaning uses high-frequency sound waves to generate a phenomenon known as cavitation, in which millions of microbubbles form and collapse in a cleaning liquid. These bubbles release energy in the form of microjets that remove dirt from the surfaces and cavities of metal parts without causing damage. The ultrasonic cleaning process consists of the following elements:

• Ultrasonic generator: Converts electrical energy into ultrasonic waves.
• Transducers: Transform ultrasonic waves into mechanical vibrations in the cleaning liquid.
• Cleaning tank: Container where the parts are immersed together with the cleaning solution.
• Cleaning solution: Mixture of water and specialized detergents that enhance the removal of contaminants.
• Cleaning time and temperature: They are adjusted according to the type of part and the dirt present.

Cleaning of metal parts - Types of parts

Ultrasonic cleaning machines are designed to work with a wide variety of metal parts, including:

• Precision parts: Gears, bearings, valves, nozzles and injection components.
• Tools and molds: Dies, matrices, plastic or metal injection molds.
• Electronic components: Contacts, printed circuits and metal connectors.
• Automotive parts: Pistons, carburettors, injectors, brake systems and gearboxes.
• Medical and dental instruments: Tweezers, scalpels, metal prostheses and surgical tools.
• Jewelry and watches: Chains, links, watch faces and metal ornamental parts.

Thanks to the action of cavitation, cleaning is uniform and effective, reaching hard-to-reach areas where traditional methods cannot reach.

 

Applications of ultrasonic cleaning for cleaning metal parts

Ultrasonic cleaning has become a key technology in various industries due to its effectiveness and versatility. Some of the sectors that benefit most from this technology are:

1. Automotive Industry
In the automotive sector, cleaning metal parts is crucial to ensure the correct assembly and operation of mechanical components. Ultrasonic cleaning is used to remove oil residue, carbon and metal particles from parts such as carburetors, injectors and brake systems.

2. Aerospace Industry
Metal parts used in aircraft must meet strict cleaning standards. Ultrasonic technology allows for the removal of contaminants without affecting the precision of critical components such as turbines, valves and engine parts.

3. Medical and Dental Industry
Cleaning surgical and dental instruments is vital for patient safety. Ultrasonic technology ensures complete removal of biological and chemical residues from tools such as scalpels, tweezers, prosthetics and dental equipment.

4. Electronics Industry
In the manufacture of electronic devices, metal connectors and microcomponents must be completely free of impurities to ensure proper conductivity. Ultrasonic cleaning removes solder residue, oils and dust without damaging delicate circuits.

5. Jewelry and Watches
The restoration of high-end jewelry and watches requires meticulous cleaning without affecting the integrity of precious metals. With ultrasonic cleaning, dirt and oxides accumulated on the most delicate pieces are removed without risk of deterioration.











Benefits of ultrasonic cleaning on metal parts
Using ultrasonic cleaning for cleaning metal parts offers numerous advantages compared to traditional methods:

1. Total removal of contaminants: Ultrasonic cavitation removes residue without the need for manual intervention, ensuring homogeneous cleaning throughout the part.
2. Damage-free cleaning: Unlike sandblasting or aggressive chemical cleaning, ultrasound does not wear down or modify the properties of the metal.
3. Access to difficult areas: It can clean cavities, perforations and complex geometries that would be inaccessible using other methods.
4. Reduced use of chemicals: It reduces the dependence on aggressive solvents, which decreases the environmental impact and improves safety in the work environment.
5. Time and cost savings: The cleaning process is faster and more efficient, reducing downtime and improving industrial productivity.
6. Extending the life of parts: By removing impurities without altering the structure of the material, the durability and efficiency of the components is prolonged.
7. Standardizing the cleaning process: Uniform cleaning is achieved on all parts without variations between production batches.

 

Choosing the right ultrasonic cleaning machine

When selecting an ultrasonic cleaning machine for metal parts, it is important to consider:

1. Size and capacity of the tank: It must be appropriate for the volume and dimensions of the parts to be cleaned.
2. Ultrasonic frequency: Lower frequencies (20-40 kHz) are ideal for removing thicker residues, while higher frequencies (60-120 kHz) are perfect for delicate parts.
3. Type of cleaning solution: It must be compatible with the material of the parts and the residues to be removed.
4. Filtering and recirculation system: It allows to extend the useful life of the cleaning liquid and maintain a more efficient process.
5. Automation and customization: Depending on production needs, automatic loading and unloading systems or customized settings can be integrated.
