Thread rolling and secondary operations for aerospace fasteners at wire Dusseldorf 2026

“In the aerospace sector, a fastener is not simply a component—it is a critical safety element.”

The fastener manufacturing sector is undergoing a structural transformation driven by full digitalization, industrial connectivity, and advanced automation. In this evolving landscape, Saspi will participate in wire Dusseldorf 2026 presenting machinery engineered to meet the combined demands of aerospace-grade precision, process reliability, and data-driven production.

With more than 60 years of experience in boltmaker machinery, Saspi continues to develop solutions for safety-critical fasteners, where dimensional accuracy, repeatability, and traceability are mandatory. At the exhibition, the company will showcase the GV2evo thread rolling machine and the MPA14CL-UG secondary operation machine, both conceived for highly demanding and fully digitalized manufacturing environments.

GV2evo: process stability and Industry 4.0-ready thread rolling

The GV2evo represents the latest generation of Saspi’s thread rolling technology. Designed to process difficult-to-process materials such as titanium alloys and nickel-based superalloys, it ensures stable production with micron-level tolerances. Its high-mass cast iron structure guarantees vibration damping and thermal stability during long production runs.

A stand-out feature is the patented motorized die pressure adjustment system, which enables precise and repeatable control of rolling forces, reducing surface defects and material tearing. The 15-degree single pusher configuration improves material flow and die life, while optional induction heating enhances ductility during cold forming without compromising mechanical properties.

From a digital perspective, the GV2evo is an Industry 4.0-ready platform, with native MQTT and OPC-UA connectivity for real-time monitoring, OEE analysis, and integration into smart factory architectures.

MPA14CL-UG: automated secondary operations for aerospace fasteners

Complementing thread rolling operations, the MPA14CL-UG is designed for the automated execution of high-precision secondary machining on screw heads, where consistency and repeatability are critical for aerospace fasteners. Derived from the MPA14 platform, the CL-UG version supports fully automatic production with minimal operator intervention.

The machine is based on a cam-less architecture, which improves flexibility, reduces mechanical wear, and lowers maintenance requirements compared to traditional cam-driven systems. This design supports faster setup changes and stable performance in high-mix production environments.

Its automatic part-flipping system repositions each fastener at the end of the first operation, enabling continuous execution of secondary head machining without intermediate handling. The MPA14CL-UG can perform facing, chamfering, drilling, and punching, either individually or combined within a single automatic cycle.

By integrating multiple operations into one machine, the MPA14CL-UG reduces cycle times, improves production flow, and ensures consistent dimensional accuracy for aerospace-grade applications.

Strategy for 2026: from machine performance to data-driven production

“As we move toward the end of Q1 of 2026, our strategy is focused on combining mechanical robustness with digital intelligence,” says Mikel Zaldua, General Director of Saspi. “Connectivity, data analysis, and automation are no longer optional. They are essential tools to help our customers achieve zero-defect production, predictive process control, and long-term competitiveness in highly regulated sectors such as aerospace.”

At wire Duesseldorf 2026, Hall 16, Stand E57, Saspi will demonstrate how precision engineering and intelligent manufacturing converge to support the next generation of aerospace fastener production.
