Turbomachinery & Energy
with PECM
Pulsed electrochemical machining (PECM) is applied in aerospace where tight geometric control, burr-free features, and repeatability across production volumes are required in materials that are difficult to machine conventionally. Voxel applies PECM to aerospace components with complex internal and external features, supporting consistent feature replication while avoiding tool-induced damage or residual stress. PECM particularly well suited for applications where edge condition, internal surface quality, and part-to-part consistency directly impact performance and reliability.

Rotating Equipment
Voxel applies PECM to energy-sector turbomachinery components, including blades, vanes, and rotating hardware, where consistent geometry, edge condition, and repeatability across parts are required. PECM enables burr-free machining and finishing of repeated features without tool-induced damage, supporting components used in demanding operational environments where reliability and dimensional consistency are critical over long service lives.

Micro Heat Exchangers
Voxel applies PECM to energy heat exchanger components incorporating internal channels, microfeatures, and thin-wall geometries in corrosion-resistant and high-temperature alloys. PECM supports the formation and internal finishing of these features while avoiding mechanical stresses that can compromise geometry or durability. Custom cathode designs enable repeatable feature generation across parts, supporting thermal systems where flow uniformity and long-term performance are essential.

Flow & Pressure
Voxel applies PECM to energy-sector flow control components where internal surface quality, repeated precision features, and consistent geometry directly influence system efficiency and reliability. PECM enables burr-free machining of internal passages and flow features that are difficult to access mechanically, supporting components used in fluid handling and pressure management applications where geometric variation or internal defects can degrade performance over time.
