Over the past 10 years, our R & D is mainly focused on this sector, developing specific processes and machines for the manufacture of various components, in order to save material in the manufacturing process.

In DENN, we understand your needs and we have the solutions.

A process of metal forming by rotation (or spinning) is used for the manufacture of pressure vessels and containers. The special configuration of this sort of machine allows both the starting tube fixation and the “heating” work by means of an external induction unit so that the corresponding fusion of the steel occurs to ensure the container sealing. The pressure vessels are used for oxygen bottles (immersion bottles), CNG (compressed natural gas), hydraulic accumulators, etc.
