Denn, Spinning with automation
Since its establishment in 1885, DENN has manufactured metal spinning machinery. Its range range of machining solutions have evolved from the traditional manual lather spinning machines to the latest in automation and in process control.
Denn technologies
Flow forming
Thanks to the resources and research, development and innovation that Denn has dedicated to this area of technology, we are world leaders in the sector. We have supplied our equipments to the biggest companies of this sector.
Shear Forming
Shear forming, also referred as conical flow forming (concave and convex flow forming) or shear spinning, is an incremental metal forming process similar to metal spinning. But in shear forming, the diameter of the final piece is approximately equal to that of the original flat sheet metal blank.
Necking in
The machinery designed by DENN for the closing of tubes in high temperatures is prepared to work with pieces at temperatures over 1000º c, which allows the manufacturing of containers for fluids at high pressure without welding.
A system of inert gas injection, developed by DENN, avoids the formation of cracks at the bottom of the container.
