_ Finishing processes
Precision finishing
More and more demanding quality standards on the market are dramatically increasing the importance of precision surface finishing processes. These treatments improve the aesthetic appearance of metal parts, but also their mechanical and physical characteristics, corrosion resistance and lifespan, among others.

Smoothing
Processes related to smoothing metal surface allow to achieve uniformity of product for appearance’s sake, and to be safe for touching without being scratched to shreds by unfinished roughness. For moving parts, a smooth finish cuts down on friction loss, without getting into coatings.

Mirror finishing
A mirror finish is a highly-polished finish, characterized by a bright, shiny, reflective metal surface. A high-quality mirror finish is not only visually appealing, but the gradual removal of surface scratches reduces indentations or grooves on metal, which may contain contaminants, such as dirt or bacteria.

Deburring
Deburring is a material modification process that increases the final quality of the product by removing impurities with a negative impact the on the appearance of a smooth machined surface, like sharp edges or burrs, left by bending, cutting, piercing, shearing and compressing materials.

Rounding
Rounding cutting edges is crucial for the design and geometry of cutting tools in metal machining. Cutting edge geometry determines the thermo-mechanical stresses on the tool. By employing edge preparation, tool life, cutting performance, and the quality of the machined surface can be improved.

Corrosion resistance

AM Post-processing
Surface roughness of AM parts can vary depending on the technology used and parameters applied, and affects fatigue, corrosion resistance and friction properties. In order to improve the surface quality, electropolishing is postulated as the most promising the treatment to reduce roughness and defects.

Inner channels
Surface quality requirements of internal surfaces, inner channels and complex parts with blind holes have increased during the last years specially in case of injection molding, aerospace, automotive, medical, food and pharma, semiconductors and gas and fluid flow applications.

_ Industries
Aerospace
Surface finishing operations play an extremely important role in aerospace and energy sectors, since it helps to improve efficiency, while increasing reliability and durability. These parts must withstand high stress corrosive conditions, high loads with long-term lifespan and meeting demanding cycle life specifications.

Automotive
Surface finishing solutions are utilized at every level of the automotive pipeline, from garage maintenance and car restoration to manufacturers’ demands. One of the most challenging aspects has to do with safety, since the result of the surface finishing process is closely linked to the vehicle performance and reliability.

Dentistry
Dental laboratories use dry electropolishing to improve surface quality of cobalt-chrome and titanium dental parts. Smoothing, cleaning and eliminating small imperfections from removal dental prosthetics and other implanted dental parts expands their lifespan pieces and can extend the life of dental components from the inside out.

Food & Pharma
Metal components produced for food, beverages, packaging and pharma industries must comply with challenging surface finishing standards. Those surfaces should be ultra-smooth, precision finishing, thus avoiding areas for bacteria grow. DLyte achieves superior results than any other surface finishing method.

Jewelry & Fashion
These industries require a perfect surface quality as the purpose of the piece is mainly aesthetic and its value depends on a good looking. Complex geometries in jewels are hard to polish with traditional polishing methods and electropolishing is one of the techniques utilized for a better homogeneity and standardization.

Medical device
Cleanability, biocompatibility, corrosion resistance, pathogen resistance and a smooth surface without defects are crucial to comply with the function and demand on quality of the medical industries. Improving the surface’s quality on implants, instruments and equipment components increases functionalities as well as their lifespan.

Toolmaking
Overcoming the drawbacks of tool finishing is one of the main challenges in the field of surface finishing solutions, in order to achieve the lowest roughness on flat surfaces. This is why DLyte has specially created new electropolishing technologies to carry out the most challenging freeform surfaces polishing.

_ Technologies
Immersion
DryLyte is a patented technology for grinding and polishing metals by ion transport using free solid bodies. It works by combining the electrical flow created by high-precision rectifier. This results in an ion exchange, removing material from the peaks of roughness.
Projection
Our new Electro-Blasting technology, released in 2021, is a new solution that provides a stream of solid-electrolyte particles propelled by a non-conductive liquid media to improve the surface quality. The media is projected towards a localized area of the piece.

Our products

The DryLyte Technology offers a wide range of finishing media. The consumables, designed and developed in our test lab, allow us to precisely meet our customers’ requirements.

DLyte achieves homogeneous results across the surface and eliminates micro scratches, as opposed to abrasive polishing. The system works efficiently at a micro and macroscopic level.

Respects the tolerances and preserves the initial shape, even the edges, guaranteeing the most precise result. It does not round the edges as there is no mechanical abrasion of the surface.

Reduces the roughness over 80% avoiding undesired effects. Liquid electropolishing is not able to reduce the roughness more than 50% without generating side effects like orange peel or pitting.

Removes material only from roughness peaks as the diameter of the particles is bigger than the roughness profile. It penetrates internal cavities that cannot be accessed mechanically.

The DryLyte Technology ensures stable results among various batches along the electrolyte media lifespan. There is no physical wear, as would typically occur with abrasive particles.

DLyte increases the surface bearing contact area allowing uniform lubricant film distribution and improving the bearing ratio and reducing the friction between the pieces.

Reduces wear and improves fracture and fatigue strength, while improving the surface quality of metal parts. It also removes embedded free iron, contaminants and heat tint or oxide scale.

Uses only polymer particles with acids for surface improvement. It ensures that the parts meet all the appropriate requirements to pass a risk-benefit analysis evaluating biocompatibility and toxicity.

This is the only technology that allows to remove roughness and improve the corrosion resistance of the metal pieces while reducing the number of processes required in the manufacturing process.
