CNC Necking In Machine

Today's high-performance necking-in machines are designed specifically for manufacturing high-pressure gas cylinders. The high surface quality and particularly flat curvatures producible when manufacturing high-pressure gas cylinders are remarkable.

The quality lead is due to a passion for detail: the swinging rest is guided in parallel to the spindle axis on a saddle slide. Its rotating motion provides optimal metal forming. For natural-gas cars, in particular, the economy of space is crucial for high-pressure gas cylinders.

More than 100 assembled and sold machines, operating worldwide, are evidence of superior innovations and product quality provided by Leifeld, making the EN series the world's top-selling necking-in machine. Leifeld's customers particularly appreciate this high efficiency lean manufacturing machine for its short cycle times and maximum forming performance.
