Stripping of parts and components with ultrasonic machines

Stripping parts using an ultrasonic bath. In the industrial sector, thorough and effective cleaning of metal components is crucial to ensure the precision of production processes, extend the life of equipment, and maintain high finishing standards. One of the most important treatments at this stage is the removal of coatings from parts, especially in industries such as metallurgy, automotive, aviation, and shipbuilding.

Historically, coating removal has been performed using aggressive chemical methods or mechanical techniques. While these techniques are effective, they have disadvantages such as high resource consumption, risks to workers, and surface deterioration. Given this situation, ultrasonic cleaning has emerged as a cutting-edge technological solution that enables effective, safe, and environmentally friendly pickling.

Stripping is an industrial process that involves removing oxides, deteriorated surface layers, paint, impurities, and residues adhering to the surface of metal parts or other materials. This procedure is crucial before subsequent treatments such as painting, galvanizing, welding, or anodizing, as it ensures adhesion and the final quality of the finish. The objective of stripping is to leave the surface completely clean and active, that is, free of contaminants that could compromise the functionality or aesthetics of the product. In this sense, our ultrasonic cleaning machines are capable of removing all types of contaminants, paints, or coatings in general, providing a complete and uniform cleaning to ensure the best results.
 

How does ultrasonic Stripping work?

Ultrasonic stripping is based on the generation of high-frequency waves (generally between 20 and 80 kHz) within a fluid (usually water with specific solutions). These waves cause the physical phenomenon known as cavitation: the formation and collapse of millions of microbubbles that impact the surface of the submerged parts.

These implosions generate extremely intense, localized energy capable of precisely removing oxides, layers of paint, limescale, carbon deposits, grease, varnish, and other residues without damaging the base material.

Advantages of Ultrasound in Part Stripping

Below, we detail the main advantages of using ultrasound in the part pickling process compared to traditional methods:

1. Uniform and Deep Pickling
Thanks to the cavitation principle, ultrasonic waves act evenly over the entire surface of the part, even in cavities, complex geometries, holes, fissures, threaded areas, or areas that are difficult to access. This allows for deep and comprehensive cleaning, impossible with brushes, sandblasting, or manual methods.

2. Preservation of Material Integrity
Unlike abrasive blasting or aggressive chemicals, ultrasound does not erode, deform, or alter the physical state of the part. This is vital for high-precision components or sensitive materials, where the geometry must remain intact.

3. Reduced Chemical Use
Ultrasonic pickling minimizes the need for solvents or strong acids, as the mechanical action of the imploding bubbles does much of the work. This contributes to a more environmentally friendly, safer, and more economical cleaning process.

4. High Process Speed
Compared to traditional techniques, cycle times are significantly reduced, allowing for greater productivity on manufacturing lines or industrial maintenance. Complete cleaning can be achieved in a matter of minutes.

5. Automation and Repeatability
Ultrasonic cleaning equipment can be easily integrated into automated processes, with specific time, temperature, and power settings for each type of part. This ensures consistent repeatability without relying on operator skill.

6. Reduced Maintenance and Operational Savings
Ultrasonic systems require little maintenance, have a long lifespan, and allow the cleaning bath to be reused for multiple cycles. This significantly reduces operating costs in the medium and long term.

This technology is adaptable to multiple industries and types of parts, guaranteeing consistent results with reduced resource consumption and simple automation. If your company needs to optimize its cleaning or industrial maintenance processes, ultrasound is the best option for the future.
