Benefits of ultrasonic pickling
Stripping parts is a fundamental process in the industry for removing surface treatments such as paints, varnishes, and other layers overlaid on the base material.
The incorporation of ultrasonic technology has revolutionized the pickling process, offering significant advantages in terms of efficiency, precision, and sustainability.
Some of the benefits of using this type of technology are the following:
Uniform removal of surface layers
Stripping chemicals, combined with high temperature, soften layers of paint, varnish, etc. Ultrasound enhances this effect by providing mechanical action on the part. Ultrasound generates high-frequency waves that produce a phenomenon known as cavitation. This process generates micro-brushing at the molecular level, allowing the paint or varnish layers to be removed evenly across the entire surface of the part. This is true even in complex geometries, cavities, and hard-to-reach areas. Unlike traditional mechanical methods, ultrasonic cleaning ensures a uniform result without damaging the material’s structure.
Time savings and faster processing
Ultrasonic stripping systems can be up to 80% faster than other traditional methods. The micro-brushing effect produced by ultrasound accelerates the action of the stripping chemicals and makes the process much faster and more efficient. Therefore, stripping time is drastically reduced.
Furthermore, BRIO high-power technology takes the stripping effect of ultrasound to a new level. Our exclusive technology allows us to use specific frequencies that are more effective for stripping, further accelerating the stripping effect. BRIO machines achieve the fastest stripping process.
High quality surface preparation
Ultrasonic stripping ensures effective removal of surface coatings such as paints, varnishes, and other finishes, allowing parts to be refinished. This method is ideal for restoring parts to their pre-coating condition, especially useful in repainting or revarnishing processes.
Access to internal areas of greater complexity
Thanks to its ability to penetrate internal and hard-to-reach areas, ultrasonic cleaning allows work to be done on parts with complex geometries that would be difficult to treat uniformly using traditional methods.
Protecting the integrity of the base material
Unlike abrasive methods such as shot blasting or sanding, ultrasonic pickling is gentle on the part and therefore does not cause mechanical wear or affect the part’s structure.
Importance of the stripping chemical
At BRIO, we develop chemical stripping products specifically designed for use with BRIO ultrasound systems. They are completely safe for the operator and the environment, with no aggressive components. The BRCLEAN DEC range of stripping agents, combined with the high-power cleaning effect of our ultrasound, provides the most optimized solution for stripping parts.
Versatility in industrial applications
Pickling is generally performed on pieces that have been previously painted or varnished and that must go through similar processes again, such as:
- Aeronautical industry: Removal of coatings on components that require repainting.
- Automotive: Treatment of rims and other painted or varnished parts.
- Industrial maintenance: Stripping of hooks, drums and other reusable elements in painting lines.
Another specific type of pickling is weld pickling, which is distinct from coating treatment, and which can also benefit from ultrasound in certain contexts.
Ultimately, at BRIO Ultrasonics, we cover all the important factors for achieving fast, efficient stripping with highly precise finishes.
- BRCLEAN Chemicals. The chemical that softens and attacks the materials to be removed (paints, varnishes, etc.)
- BRIO Ultrasonics. They provide the mechanical micro-brushing factor that enhances the stripping effect.
- The stripping effect works optimally at a certain temperature.
- The time it takes to complete the pickling process. In the case of BRIO pickling machines, this is a very short time.
The use of ultrasound in part pickling offers key advantages in terms of time, efficiency, sustainability, and process quality. Its ability to remove coatings without damaging the base materials and optimize production time makes it a valuable technology for multiple industrial sectors. At BRIO Ultrasonics, we offer ultrasonic cleaning solutions tailored to the needs of each industry, ensuring optimal and sustainable results.
