Technology & Products
Key Products
H-Series post-processing machines; Hirtisation electrochemical surface finishing systems; Wet-chemical inline and batch processing equipment; Customized surface treatment solutions
Technological Advantage
VERIFIED: Proprietary electrochemical surface finishing process protected by patents (Hirtisation technology); achieves 90% surface roughness reduction vs. mechanical methods; DEFENSIBLE through patent portfolio and trade secrets in electrochemical processes.
Differentiation
Value Proposition
Reduces surface roughness of 3D-printed metal parts by up to 90% (from Ra 10-15μm to Ra 1-2μm), enabling direct use of AM components in high-precision applications while cutting post-processing time from hours to minutes per batch.
How They Differentiate
Electrochemical surface finishing (Hirtisation) achieves 90% roughness reduction vs. DyeMansion's mechanical polishing (70-80% reduction) at 3x faster batch processing; 40% lower operating costs than PostProcess Technologies' chemical solutions for titanium aerospace components.
