Technology & Products
Key Products
electroform® electrochemical polishing machines (ef-150, ef-300, ef-500, ef-700); acid-free ECP process with CFD and patent-pending dynamic contour technology; small-batch polishing / custom surface finishing services; R&D collaboration services
Technological Advantage
Patented electroform® process creates defensible moat against traditional polishing and abrasive methods. Technology differentiates on speed (6× faster), safety (acid-free), and suitability for complex AM topologies. First-mover advantage in dedicated AM electrochemical post-processing market.
Differentiation
Value Proposition
Reduces AM part post-processing time by 83% (6x faster) vs. traditional automated methods; eliminates surface inconsistencies on AM components; acid-free process improves durability and preserves critical geometries; enables precision finishing of complex topologies; reduces labor and chemical costs; supports refractory metals and Nitinol processing.
How They Differentiate
Holdson's electroform® is 6× faster than competing automated post-processing methods and does not use harsh chemicals (acid-free), reducing environmental and safety liability. Designed specifically for AM part geometries and capable of ultra-precise finishing (1RA). Competitors use generic electropolishing or abrasive methods not optimized for AM complexity.
