A perfect surface finish by selecting the best electrolyte to meet your machine and finishing requirements
_ 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.

Electrolyte fundamental features to treat diverse materials, geometries and finishing processes
Solid electrolytes composed of particles are more aggressive and can more effectively reduce roughness than electrolytes in suspension. This is because the liquid that contains the suspended particles offers some protection to the surface from oxidation during the process. This characteristic makes solid electrolytes particularly suitable for treating materials that are highly reactive to oxidation and require protection.
-
Size and geometry
Using particles with varying sizes and geometries allows for treating pieces with different geometries effectively by reaching hard-to-reach areas, which maximizes the surface area in contact with the electrolyte and leads to a more uniform and thorough treatment of the material. This technique provides an efficient and versatile solution for various material finishing needs.

Environmental Benefits of DryLyte Technology
Waste Management
The DryLyte Technology and the equipment it powers, DLyte, do not require wastewater or sludge treatment machinery. Both allow labor and environmental license costs savings, since the dry electrolyte required can be easily handled by standard services. In its turn, all the metal removed from the work pieces remains in the media.
The previous feature offers a clear advantage in comparison to traditional abrasive surface treatments, which require wastewater treatment machinery and the adequate space to work. It also involves labor and environmental license costs. Moreover, abrasive surface treatments need a water treatment system in order to clean the water polluted with metals and compounds.
Liquid electropolishing requires additional safety measures to be put in place for proper disposal, due to environmental concerns related to highly corrosive and toxic mixtures of phosphoric and sulphuric acids and sludges containing metals.
In addition, several liquid electrolytes may generate certain amounts of sludge which require to be removed from the tanks to keep the process stable.
Liquid electropolishing needs replacement of a portion of the used solution for a good performance and to guarantee a high-quality metal surface finishing process. The disposal of the liquid requires a specific service to ensure environmental compliance conforming to regulations.
This surface treatment method may also require a post-dip to remove residual electrolyte and by-products from electrochemical reactions. The disposal of liquids used in the post-dip process may also requires hazardous waste management.
Handling and Storage of Media and Mixtures
DLyte only uses solid electrolyte media with a low acid concentration which can be handled and stored without additional safety measures. It is not harmful for workers and, since it is solid waste, its handling reduces the probability of discharge in drains and waterways.
Abrasive surface treatment usually requires compound and chemical accelerators in large amounts, which involves a danger for workers during handling, as well as an eventual risk of discharge into the environment.
Liquid electropolishing uses highly corrosive and toxic liquid mixtures of phosphoric and sulphuric acids. This may be dangerous for professionals during handling and for environment.
This metal surface treatment usually requires a post-dip to remove residual electrolyte and by-products of the electrochemical reactions.
The handling of liquids used in the post-dip may also suppose a risk for workers, and can cause a discharge in waterways or drains.
Water Consumption
The DLyte system requires low water consumption, as it only needs water to adjust conductivity of the media.
On the contrary, in abrasive surface treatment, large amounts of water are generally necessary to polish, especially for high quality surface finishing requirements. If different materials are processed in the same media, a heavy flow of water will prevent pollution.
Exposure of Workers during Polishing and Maintenance Processes
DLyte improves working conditions and drastically reduces the toxicity of current polishing processes, as it does not generate dust, heavy noise or contact the workers with highly corrosive and toxic liquids during handling and maintenance. Metals removed from the work pieces remain in the media, so workers are not exposed to the cathode.
Abrasive surface treatment generates dust. It can be dangerous for the health, since the particles that cause damage are often invisible to the naked eye. This is why the eventual health effects of exposure can take many years to be visible. Abrasive surface equipment is usually very noisy and can lead to hearing loss in case of inadequate hearing protection or prolonged exposure to noise in the workplace.
Handling of sludge and compounds with high concentration of metals may be also harmful for workers if protective measures are not strictly ensured.
Secondly, abrasive surface treatment requires in some cases a final manual buffing to achieve the required surface quality, which involves an additional exposure to dust and toxic particles to workers.
Liquid electropolishing uses highly corrosive and toxic liquid mixtures of phosphoric and sulphuric acids in tanks which carries a high risk for workers in case of accidental splashes. Metals removed from the work pieces remain in the liquid and partially attached to the cathode. Thus, it involves a risk of exposure for workers during handling and maintenance of the tank and the cathode cleaning operation.
The post-dip process is performed in tanks to remove residual electrolyte and by-products from the electrochemical reactions. It also means a potential risk for workers in case of splashes during operation or by accident.
