Our dry electropolishing system.
The DLyte series are patented machines based on the patented Drylyte Technology for surface finishing of metal alloys for the industry. It provides a solution to the most common industrial metals and alloys. The applications for DLyte range from grinding, rounding and deburring to surface smoothing and high gloss polishing of aesthetic parts.
DLyte is a technological solution that automatizes, simplifies and standardizes the post-process of metal parts, improving the finishing results obtained with traditional polishing systems.
The First Dry
Unlike traditional polishing systems, the DLyte system obtains consistent finishing avoiding any marks on the surface, patterns such as those generated by machining, and is able to process complex geometries without generating micro scratches on the surface. DLyte respects the tolerances of the piece, delivering a mirror finish.
“The process extracts the material only from the peaks of the roughness,
it does not round the edges but penetrates the internal cavities of the piece to which cannot be accessed mechanically”.

Process key factors
The process needs to be customized for different materials. The formulation of the electrolyte and parameter of the process play a key role in the results achieved with the process.
Initial roughness, required finishing
and manufacturing process
The process uses different parameters, time of process and media size based on the initial roughness, its required finishing and its manufacturing process.
Shape, complexity and size of the piece
Different geometries, shapes and sizes of the piece require different movements and parameters to allow an optimal flow of the media and electricity through the surface achieving homogeneity across the piece.
DryLyte vs Liquid Electropolishing
DryLyte achieves lower surface roughness than liquid electropolishing.
DryLyte avoids some side effects of the liquid electropolishing as oxidation, passivation, milky surface, orange peel, etc.
DryLyte performs homogeneous results across the piece as the electricity flows through the media without taking a straight way as it happens with the liquids. Internal channels can be polished by DLyte with the application of internal cathodes that allows direct conductivity through these channels. The distance of the cathode to the piece is in case of DryLyte less critical than with liquid electropolishing.
DryLyte does not create waviness on the surface as the liquid electropolishing does.
DryLyte is able to perform grinding and polishing in one step and liquid is only able to perform polishing.
DryLyte is grinding the surface in a selective way layer by layer using a media with diameter bigger than the roughness profile avoiding the media impact on the valleys of the surface. The liquid is interacting also in the valleys of the surface being not able to perform a selective grinding.
The use of solid media allows to focus the process in specific area of the part. Some areas of the pieces can be blocked with a lack or cover avoiding the process to interact.
DryLyte increases the resistance against corrosion versus liquid electropolishing.
Easy of use
The Drylyte Technology is very stable in terms of parametrization compared to liquid electropolishing where any change of the total surface to be treated needs adjustment of the parameter.
The Drylyte Technology guarantees controllable results as it is less aggressive than liquid electropolishing.
The media is easy to be handled and it is not hazardous for workers.
The risk of contamination of the environment is lower with the dry media than with the liquid.
DryLyte vs Abrasive Polishing
Easy of use
The cleaning process after the DryLyte process is just a soft ultrasonic or steamer process on any hard metals, oils or other products that remain on the surface of the piece. The Drylyte process needs the part to be connected or fixed at any time to allow conductivity during the process.
The electrolyte media is easy to be handled and it is not hazardous for the workers. No need of waste water management in the production plant associated to the DryLyte process. The DryLyte process does not generate dust and noise.
DryLyte achieves lower surface roughness than abrasive polishing. The DryLyte process is more than 5 times quicker than mechanical abrasive polishing.
The DryLyte process does not round the edges of the pieces as the way of polishing is by ion transport and not applying pressure and movement as the abrasive polishing does.
Drylyte process is able to polish in small corners and dead zones as it is only needed to arrive to the area and apply electricity. Abrasive polishing has big difficulties to polish in those areas as it is not able to apply pressure and movement with accuracy.
Internal channels can be polished by Drylyte with the application of an internal cathode that allows direct conductivity through these channels. The limits of the technology in those cases are the size of the cathode, the geometry and size of the channels and the size of the media.
The use of soft media allows to focus the process in specific area of the part. Some areas of the pieces can be blocked with a lack or cover avoiding the process to interact.
Drylyte increases the resistance against corrosion versus abrasive polishing.
