When it comes to high productivity and excellent quality, spinning is the process to look at. For ventilators, fans and other ventilation components, DENN has a variety of machines, from spinning to flanging & punching machines. Reliable and fast process, with low cost in tooling. One single piece in one work step makes this technology a competitive process compared with other slow and less quality processes.

Through a spinning process starting from a blank, DENN machines can easily obtain a final bellmouth part, ready to be assembled and installed, with an excellent top surface quality. Bellmouth manufacturing process and cycle time are definitely shorter than other processes used in this industry. With many references in this field, DENN is leading this market sector. Our machines can work bellmouths up to 3 meters and even more.

Metal gaskets are designed to withstand extreme temperatures, pressures and chemical exposure very common situations within the aerospace industry. These rugged metal gaskets are made of a wide range of materials to accommodate all types of sealing applications.

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.

The weight reduction and improvement of the mechanical properties are main benefits of the flowforming process .

DENN provides high accuracy CNC Cad-Cam machines specially designed to the After-Market and OEM industries adapted to each customer’s production volume.
