HOT SPINNING MACHINES
The heavy-duty necking-in machines of the SM series were specially developed for hot spinning og high pressure gas cylinders. This machines can deform tube which has previously been heated to make the bottoms and the necks. The heat-processed surfaces and the length of every cylinder are then controlled.
