Technology & Products
Key Products
Abrasive Flow Machining (AFM) machines; Electrochemical Machining (ECM) machines; Thermal Deburring machines; COOLPULSE technology for surface finishing of metal 3D printed parts; Contract Shop Services; Aftermarket parts and service
Technological Advantage
Proprietary AFM process, invented and patented by the company, provides a unique capability to finish internal channels and complex geometries in metal AM parts that are inaccessible to conventional tools. The COOLPULSE technology offers an economical way to refine rough surface finishes on metal 3D-printed parts. The company's decades of experience and process knowledge in high-end surface finishing create a significant barrier to entry for competitors.
Differentiation
Value Proposition
Reduces post-processing time and cost for metal AM parts by providing automated finishing solutions that reach internal channels and complex geometries, improving surface finish and part performance while eliminating manual finishing bottlenecks.
How They Differentiate
Extrude Hone differentiates through its proprietary AFM technology, which is specifically designed for finishing internal and hard-to-reach areas of complex metal parts, including AM components. Unlike general machining or manual finishing, AFM provides consistent, repeatable results for internal channels and passages. The company also offers a range of complementary technologies (ECM, thermal deburring) and contract shop services, providing a complete finishing solution.
