Our customers rely on us to provide them with best machinery and tooling for their production needs. We study each machinery project thoroughly, and we look at all machinery, technology and tooling options available to us. If none of these options are perfect for the required task, then we go into R&D mode – striving to turn the seemingly impossible task into a possible task. We are not just machinery suppliers, we are production solutions suppliers; this includes parts production process research & development, tooling engineering, tooling manufacturing and programming. We supply complete turnkey solutions.

Industrias Puigjaner- DENN has been building spinning machines for over 125 years and has always aimed to improve manufacturing technologies and machinery. The company has an impressive mix of employees with decades of experience, and employees with youthful ideas and drive for new developments and technologies. DENN has also established many strategic partnerships with research institutes and other companies which share our determination in continuing to advance chipless forming technologies and machinery.

Don’t Ignore Metal Forming Lubricants

18 Jan

For metal working and metal forming you will need to make sure that you use good quality lubricants.
In your machinery you want to use fluids, oils and coolants which protect and extend tooling life, provide superior surface finishes on the parts you produce, allow faster speeds (cycle times), are easily cleaned up and are safe for the machinery operators.

Going Big in July 2012 – Going Bigger in 2013

11 Jan

On July 3, 2012 we blogged about going big with a DENN CTA-660 CNC tube (cylinder) spinning machine. Now, about 1/2 a year later we go even bigger.
Currently being built is a DENN CTA-720 CNC tube (cylinder) necking-in machine.
This will be the current largest machine in the world for cylinder necking-in operations.
Diameters up to 711 mm (28 inch) and material thickness up to 40 mm (1.57 inch).
Lengths of tubes up to 13,600 mm (44.6 feet).

Going Big! DENN CTA-660 CNC tube necking-in machine

3 Jul

Our DENN CTA-660 CNC tube necking-in machine is one of the largest tube necking-in machine in the world. This heavy-duty machine is capable of working with tube lengths from 3 m (9.8′) to 12 m (39.4′); and material thicknesses from 11 mm (0.43″) to 35 mm (1.38″). Tubes out of aluminum, steel, titanium, or other materials can be end-formed with a wide variety of profiles.
