DLyte eBlast for Localized Surface Finishing │ DLyte

DLyte eBlast

Projected dry electropolishing
for focused surface finishing

Reach every hard-to-access
corner in even the most
complex geometries

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.

Hardware features

Precise targeted surface finishing

With eBlast, achieving precise surface finishing is easy thanks to the variety of guns and nozzles available that are specifically designed based on the geometry of the metal part. By carefully selecting the appropriate gun and nozzle and adjusting the application distance, you can effectively produce the exact surface finish you desire with great accuracy.

Efficient recirculating system

Our recirculating system pumps electrolytic media, which is a mixture of liquid and particles, through the eBlast gun and into the working cabin. The user has complete control over the stream and can direct it to the specific areas to be polished. The gun is designed with an electrode to ensure that the particles emitted from the nozzle have electrical connectivity.

Powerful electric system

Its electric system comprises a power source connected to the metal part and an electrode situated in the nozzle. The closed circuit is established between the power source, electrode, particles, and surface, allowing for a steady flow of current. This design ensures a powerful and efficient system that contributes to the precise surface finishing achieved with eBlast.

Operative features

Robotic collaborative arm

This system uses a robotic collaborative arm to automate the surfacing process. The arm efficiently directs the flow of electrolyte media over the desired surface area, improving the overall performance of the process. This automation ensures consistent and accurate results, while also reducing the risk of human error.

Full connectivity provided

DLyte eBlast enables real-time monitoring of electrolyte control and process traceability. This feature satisfies the industry's most demanding requirements, ensuring consistent and reliable results. With DLyte eBlast, users can track and analyze the process to make data-driven decisions that improve efficiency and optimize performance.

Spacious work area

Designed to accommodate up to 300 kg and a maximum piece volume of 1,000 x 500 x 500 mm. Operators can work comfortably with larger and heavier parts, allowing for increased productivity and efficiency. Additionally, the system's safety gloves provide direct access to the work area, facilitating precise and accurate control.

Projection systems

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.

Electro-Blasting

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.

Complex Geometries

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

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.
