Mirror finish for large and heavy metal parts, even with complex geometries, that are hard to polish using immersion methods.
Especially effective for blind holes, slots, occluded areas and inner channels.
DLyte eBlast uses a stream of solid-electrolyte particles propelled by a moderator liquid media to deliver targeted surface finishing for metal parts.
This patented electro-blasting method is ideal for achieving focused surface finishes.
DLyte eBlast features a collaborative robot and a variety of guns and nozzles for precise surface finishing based on the piece’s geometry and application.
It can handle up to 300 kg and pieces with a maximum volume of 1,000 x 500 x 500 mm.
The Dry Projection technology, released to be used in the DLyte eBlast machine, is a new solution that provides a stream of solid-electrolyte particles propelled by a moderator liquid media to improve the surface quality. The media is projected towards a localized area of the piece.
In comparison to liquid electropolishing, this non-electrically conductive liquid is not directly involved in the surface finishing process. Its main function is carrying the particles; its specifically developed composition contributes to maintain the connectivity and conductivity between particles during the process. Additionally, this liquid creates a protective layer over the metal surface, accumulating especially in roughness valleys, thus protecting the surface from pitting.
This new projected electropolishing opens up a wide range of possibilities for the treatment of metal surfaces with non-homogeneous roughness or complex geometries (the current main obstacle of AM parts), as well as large, heavy pieces. This feature can provide finishing solutions in sectors such as 3D printing, automobile industry, railway and specially injection molds.
How it works
The Dry Suspension system is based on a mixture of solid particles and liquid for projection systems.
Particles collide with each other through the liquid emulsion which, when agitated, becomes conductive.
Dry suspension’s benefits
+ Higher adaptability and customization.
+ For complex geometries.
+ Part protected by the liquid.
Internal surfaces of complex geometries can be easily treated as the stream of electrolyte and current can be effectively directed to the target surface. This improves the results obtained with abrasive polishing and electropolishing, where some surfaces become unpolished.
Inner channels with a diameter of at least 20 mm and open angles can be effectively polished using an electrode located at the tip of the nozzle. The high viscosity of the media flowing through the cavities maintains the connectivity of the polishing particles, keeping the surface protected and clean.
Delicate and Fragile Parts
Delicate and fragile parts can be finished without being harmed as the process does not use vibration nor strong mechanical forces. As the media stream has low pressure, pieces can be electrically connected without a tight fixation.
