DLyte PRO500®

The Most Advanced Metal Surface Polishing Machine on the Market

The DLyte PRO500® is the most advanced, powerful, and versatile metal surface finishing system on the market specially designed for mass production. Powered by DryLyte technology, a new patented technology for the treatment of metal surfaces by ion transport using free solid bodies. The process precisely extracts material only from the peaks of the roughness and penetrates the internal cavities of the metal part to which it cannot be accessed mechanically. It does not round the edges. Instead, it provides high-quality metal surface finishing better, faster, and more efficiently.
The DLyte PRO500 system can be integrated into any manufacturing line, requiring highly complex grinding and polishing processes. It combines an intelligent, and robust design with a high output in a very small footprint.

Polish and Smooth Metal Parts with Precision at Scale

The DLyte PRO500® is powered by patented dry-electropolishing technology which uses solid media (electrolytes) combined with an electrical flow and movement to create a clean and precise polishing process. The system can process multiple metal parts during one cycle with a wide range of material compatibility. DLyte PRO500 includes 3 mechanical movements on each of the 8 perimeter spindles. You can process single or multiple metal parts per holder, which means an optimized capacity and performance.

The DryLyte® technology for surface finishing of metal alloys has various applications that range from grinding, rounding, and deburring to surface smoothing and high gloss polishing of aesthetic parts. DLyte offers the solution for an automated post-process of metal parts, improving the finishing results obtained with traditional polishing systems.

10 x faster

Up to 10 x faster than current processes. DLyte technology and systems replace multiple steps in the metal surface finishing process.

Proto3000_Environmental icon

Biocompatibility proven

Clean, non-hazardous, and easy waste management. Alternative abrasive processes lead to extremely dusty and noisy environments.

Proto3000_Skewness icon

Negative surface skewness (rsk)

Enhanced negative surface skewness (rsk) which increases the surface bearing that allows uniform film distribution) improving the bearing ratio and reducing the friction between the pieces.

Proto3000_Isotropic Surface icon

Isotropic surfaces

Due to the DryLyte technology, generating grinding texture patterns is avoided, thus improving wear and fracture resistance, as well as fatigue resistance.

Proto3000_Corrosion Resistance icon

Improved corrosion resistance

DLyte is the only system that is able to remove roughness and improve the corrosion resistance of the metal parts at the same time reducing the number of processes required in the manufacturing process.

High capacity and versatile

DLyte PRO500®. One system, multiple applications. It is equipped with 8 perimeter spindles allowing polishing of one or multiple pieces each, using different holders, for a maximum volume of
180 x 250 mm per spindle. The cathode is very close, allowing optimization of capacity as well as improving material removal during the process. Moreover, the system includes a centered spindle for larger parts with a maximum volume of 500 x 250 mm. This, combined with the bottom work bowl cathode, ensures homogenous finishing across the piece.
The relationship between the surface of the workpiece and the volume of the electrolyte is reduced, improving the electrical current flow and reducing the temperature and the possibility of pitting on the parts’ surfaces.
