What HWR Clamping Technology does

HWR Spanntechnik GmbH is a privately held German manufacturer of precision clamping technology for metalworking applications, founded approximately 35 years ago and headquartered in Oyten, Germany. The company operates two principal product platforms: the INOLine® family of concentrically clamping chucks (INOFlex®, INOTop®, INOZet®) designed for cubic and round workpieces including deformation-susceptible components, and the SOLIDLine family of zero-point clamping systems (SOLIDPoint®, SOLIDBolt, SOLIDGrip, SOLIDStamp) built around high pull-in forces and modular, seconds-rigging setups. Patented compensation technology in the INOFlex® line and a 96mm-standardized interface across the SOLIDLine ecosystem underpin the technical positioning.

The business sells exclusively to industrial B2B customers — precision machining and metal-cutting companies, CNC job shops, agricultural equipment manufacturers, and automation integrators — via quote-based pricing on multi-year contracts. Commercial reach is delivered through more than 36 field representatives worldwide, regional distributor partnerships (e.g., NK Works for Japan, Venten OÜ for the Baltics), direct regional coverage in DACH, and a US-facing website, supplemented by active participation in industry trade fairs (AMB Stuttgart, JIMTOF Tokyo, Tech Industry Riga). Recent strategic emphasis has shifted toward automation and robotic integration, evidenced by four AMB 2024 launches (SOLIDPoint® RoboConnect, INOFlex® VFA, SOLIDBolt pallet adapter, INOFlex® VT-Q), a ground-breaking for a second plant in November 2024, and a series of senior commercial hires in 2025–2026 including the establishment of a dedicated marketing and brand management function.

Core offering

HWR Spanntechnik GmbH manufactures precision clamping technology systems for metalworking and machining applications. Its portfolio spans the INOLine and SOLIDLine product families, covering flexible compensating clamping chucks (INOFlex, INOTop, INOZet), zero-point clamping systems (SOLIDPoint, SOLIDBolt, SOLIDGrip), power chucks with quick-change jaws (INOFlex VT-Q), hydraulically actuated automation vices (INOFlex VFA), and pneumatic robot-adaptation interfaces (SOLIDPoint RoboConnect) used by industrial manufacturers performing CNC turning, milling, grinding, and multi-task machining.

Product overview

HWR Clamping Technology is a clamping technology manufacturer offering two main product lines: INOLine and SOLIDLine. INOLine focuses on quality and precision, providing concentrically-clamping systems (INOFlex, INOTop, INOZet) for square and round components, including deformation-susceptible workpieces. SOLIDLine expands the product portfolio with zero-point clamping systems (SOLIDPoint, SOLIDBolt, SOLIDGrip, SOLIDStamp) designed for rapid set-up and automation applications. Key products include INOFlex flexible clamping systems with patented compensation for various geometries, and SOLIDPoint zero-point technology with high pull-in forces. Recent additions include INOFlex VFA (hydraulically actuated automation vice), INOFlex VT-Q (power chuck with jaw quick-change), SOLIDBolt pallet adapters for automation, and SOLIDPoint RoboConnect for robot adaptation. The company has over 35 years of experience and collaborates with more than 36 representatives worldwide.

• INOFlex VT-Q Power chuck with through-hole and jaw quick-change system; the jaw quick-change system enables changeover to new clamping situations in seconds, significantly reducing set-up times and enabling higher productivity.
• INOFlex VFA Hydraulically actuated 4-sided automation vice designed for automated workpiece changing; hydraulic actuation enables quick workpiece changes and greater flexibility.
• INOTop Concentrically and compensating clamping chuck for clamping square and round components.
• INOZet Clamping solution for concentric and compensating clamping; used by series production manufacturers such as EMB Zerspanungstechnik for high-quality series production.
• SOLIDPoint Zero-point clamping system with one of the highest pull-in forces available on the market; module set-up enables rigging in seconds for any application.
• SOLIDPoint RoboConnect Interface for pneumatic robot adaptation based on SOLIDPoint zero-point technology with one of the highest pull-in forces on the market; combination plates with 96mm interface.
• SOLIDBolt Pallet Adapter Zero-point clamping system for automation pallets based on the SOLIDPoint principle with reversed interaction between fixture and stud, functioning as a pallet adapter.
• SOLIDGrip Centering chuck for zero-point clamping systems; module set-up enables rigging in seconds for any application.
