Manufacturing Technology

For over 60 years, SASPI has been a driving force in the fastener industry, consistently delivering robust and reliable machinery, with a commitment to innovation evident in the latest generation of thread rolling and secondary operation machines, designed to meet the evolving demands of a global market.   

SASPI’s thread rolling machines are a testament to the company’s dedication to combining time tested reliability with cutting edge technology. These machines are not simply updated versions; they are fundamentally reengineered to provide unparalleled performance and efficiency.

One of the cornerstones of SASPI’s thread rolling technology is their continued development of cast iron body designs. Leveraging advanced technology, they harness the inherent shock absorption and heat expansion properties of cast iron, a feature unmatched by alternative materials. The incorporation of servo-driven camless technology further enhances precision and control.   

Furthermore, user-friendliness is a priority, reflected in features such as motorised rails, feeding systems with extended life carbide inserts, as well as tool-free set-ups. In addition, ergonomic design and adherence to the latest CE safety standards ensure operator comfort and safety.   

The latest generation of machines also feature SASPI’s patented die pressure adjustment, electronic handwheel jogging, and touchscreen controlled die match, adaptable to modern process monitoring. To add to this, a motorised die pressure adjustment, unique to SASPI, offers an unparalleled level of control, as well as a 15 degree single pusher system to extend die life and enhance thread quality.   

In-line with Industry 4.0 standards, SASPI machines also offer wireless remote accessibility and seamless integration with MQTT and OPC-UA protocols, along with built-in OEE performance control. 

These features have solidified SASPI machines’ position in key industries such as aerospace, automotive, construction and household sectors – a testament to their proven reliability and performance. Furthermore, every SASPI thread roller can be integrated with secondary operation units, washer assembly units, or stud feeding systems, offering a comprehensive production solution.   

High-speed, precision secondary operations

SASPI’s secondary operation machines are renowned for their speed, precision and versatility. The ability to perform multiple operations simultaneously, including shaving, drilling, broaching, and head operations, sets them apart.  

The MPA series, particularly the MPA-14CL, exemplifies this advanced technology. These automatic pointing machines are fully motorised, allowing for precise adjustments and easy operation. A unique feature is the ability to hold parts close to the machining point, minimising vibrations and maximising precision, regardless of part length.   

The MPA machines handle a wide range of materials, from steel alloys and heat treated parts to titanium and inconel, making them ideal for diverse applications such as the aerospace industry. The MPA-14CL, with its camless design, provides unparalleled flexibility enabling fully adjustable cutting strokes and even pecking drilling for deep holes.   

Also available is the DOM-16, a secondary double operation machine, which offers simultaneous pointing, drilling and broaching capabilities. Designed primarily for the aerospace sector, its speed, precision and versatility, make it a valuable asset for high demand applications.   

SASPI maintains a strong global presence, with test and demonstration machines available at its Spanish headquarters, as well as technology centres in North America and China. This commitment to accessibility ensures that customers worldwide can experience SASPI’s advanced technology first-hand.
