Extrude Hone

What Extrude Hone does

Extrude Hone is a privately held precision surface finishing company founded in the 1960s and headquartered in Irwin, Pennsylvania, with approximately 320 employees operating across 10+ global facilities in the United States, United Kingdom, Germany, France, Italy, India, China, and Japan. The company provides three complementary core technologies — Abrasive Flow Machining (AFM), Electrochemical Machining (ECM), and Thermal Deburring (TEM) — for deburring, polishing, radiusing, shaping, and flow tuning of metallic components in industries including aerospace, automotive, energy, medical devices, die extrusion, fluid power, firearms, and general industrial manufacturing. Its capital equipment portfolio includes the VECTOR AFM machine (400+ units deployed in 22 countries), ECOFLOW, EASYFLOW, SPECTRUM, ONE WAY FLOW, the new ECO+ modular ECM system, and the T Series (T250/T350/T450) thermal deburring machines.

The company operates a three-pronged business model: capital equipment sales of finishing machines and tooling, contract shop services at multiple global locations where customers outsource component processing, and aftermarket support including spare parts, media, and cathodes for the installed base. Extrude Hone holds aerospace-specific certifications (AS9100, NADCAP, Rolls-Royce Certificate of Approval) and ISO 9001/14001 quality certifications across its facilities, and serves a blue-chip customer base including Rolls-Royce, BESCAST, Unitech, and CDC. The company was acquired by Madison Industries from Kennametal in December 2015, and in June 2026 Gladstone Investment Corporation announced a definitive agreement to acquire Extrude Hone LLC, pending regulatory approval. Extrude Hone also operates a specialized additive manufacturing finishing sub-brand, positioning for the metal AM post-processing market.

Revenue model

1. Capital Equipment Sales: Sale of finishing machines (AFM, ECM, TEM systems), tooling, and accessories. Customers can purchase equipment for in-house processing.
2. Contract Shop Services: Outsourced finishing services at multiple global locations. Customers process components at Extrude Hone facilities rather than purchasing equipment. Serves as both standalone service and customer acquisition channel.
3. Aftermarket/Spare Parts: Spare parts, service support, media, and cathodes for customers who have purchased equipment. Ongoing support relationship with installed base.

Core offering

Extrude Hone manufactures and sells precision surface-finishing capital equipment and provides outsourced Contract Shop services based on three proprietary technologies: Abrasive Flow Machining (AFM), Electrochemical Machining (ECM), and Thermal Deburring (TEM). The company supplies machine systems (VECTOR, ECO+, T Series, etc.) and tooling to aerospace, automotive, medical device, energy, and industrial manufacturers for deburring, polishing, radiusing, shaping, and flow tuning of metallic components—particularly internal passages and complex geometries inaccessible to hand finishing methods.

Product overview

Extrude Hone is a precision surface-finishing solutions provider operating as a platform of three core technologies: Abrasive Flow Machining (AFM) including Microflow variant, Electrochemical Machining (ECM) with Static and Dynamic capabilities, and Thermal Energy Method (TEM). The company offers capital equipment (machines and tooling), contract shop services, and aftermarket support worldwide. Capital equipment includes VECTOR (the flagship AFM system with 400+ units globally), ECOFLOW, EASYFLOW, SPECTRUM, ONE WAY FLOW for AFM applications; ECO+ modular ECM systems; and T Series (T250, T350, T450) for thermal deburring. Services include contract manufacturing through a global shop network and comprehensive aftermarket support including media and cathodes. The company also operates a specialized additive manufacturing finishing division (Extrude Hone Additive).

Functional benefit

Products and services

• Abrasive Flow Machining (AFM) Core proprietary technology using abrasive-laden viscoelastic media forced through component passages under hydraulic pressure to polish, deburr, and radius internal surfaces and complex geometries. Sold as capital equipment (machine families including VECTOR, ECOFLOW, EASYFLOW, SPECTRUM, ONE WAY FLOW) and as a Contract Shop service.
• Microflow Radiusing technology for flow tuning of small orifices combined with polishing and deburring, based on hydrogrinding principles. Designed for precision micro-scale finishing and small passageways.
• Electrochemical Machining (ECM) Deburring and edge radiusing technology using electrochemical dissolution to machine metal components without mechanical or thermal loads. Suitable for hard-to-machine materials and hardened metals.
• Dynamic ECM Advanced electrochemical machining process providing precision solutions beyond traditional static ECM, used for long gun barrel rifling with negligible precision variation between 2000 and 8000 shots.
• Thermal Deburring (TEM) Pure deburring technology using a combustion process. Sealed chamber filled with methane and oxygen is ignited by a spark, producing a heat wave up to 6000°F that oxidizes burrs without touching the surface, with cycle times under 1 minute.
• VECTOR Abrasive Flow Machining System High-pressure industrial AFM system offering pressures up to 276 bar with advanced process control for consistent, automated finishing. 400+ units deployed in 22 countries; flagship AFM product and best seller in its category.
• ECOFLOW Compact and cost-effective AFM solution for aluminum extrusion die polishing and finishing, suitable for tooling workshops and medium production volumes.
• EASYFLOW Versatile AFM system for medium production volumes with media cylinder up to 250mm, offering flexible configuration for various extrusion applications.
• SPECTRUM High-capacity AFM machine with media cylinder up to 600mm, designed for processing larger closed impellers and high-volume industrial applications.
• ONE WAY FLOW AFM machine with 250mm media cylinder designed for one-way flow processing, particularly suited for closed impeller finishing.
• ECO+ Modular ECM System Modular ECM concept with five configurable packages allowing customers to configure machines to their specific requirements. Reduces delivery time while offering high modularity and enhanced precision ECM results.
• T Series Thermal Deburring Machines (T250, T350, T450) Thermal Deburring machine family: T250 for small to medium parts and compact manifolds; T350 and T450 for larger parts and high-volume production.
• Contract Shop Services Outsourced precision finishing services at 10+ global locations. Customers can process components at Extrude Hone facilities using AFM, ECM, and TEM technologies without purchasing equipment, serving as both a standalone service and a customer acquisition channel to eventual equipment sales.
• Aftermarket Support Comprehensive support services including spare parts, service, media, and cathodes to maximize equipment performance throughout the customer lifecycle.
