Application area
Automotive
Leifeld und Nihon Spindle specialise in the development of high-performance machines for manufacturers in the automotive sector. Our machines fulfil the highest expectations - and thanks to their continuous evolution, we even exceed them. This is how we support customers each and every day with our optimum cold and hot forming solutions. Discover the application areas of our machines in the automotive industry: wheels, brakes, transmission parts, powertrain, exhaust parts, tanks, e-mobility and more.
Aluminium Wheels
Our machines and solutions enable the production of highly stress-resistant and at the same time extremely lightweight aluminium wheel components. By applying heating, it is possible to machine aluminium alloys that are difficult to form. In combination with our patented variable inner tool, different base widths and geometries can be produced without changing tools.

The demand for electric vehicles is strongly growing. The market requires high performance e-motors and drive trains as well as high power batteries with increased range. According to the market requirements we have developed innovative processes to produce weight-optimized rotor shafts from one piece.
Motor components
Rotor shaft
| Forming workpieces from a tube, a forged thickwalled preform or a formed thinwalled preform | |
| Production of extremly sturdy rotor shafts from a single piece | |
| High material utilisation accompanied by improved strength and hardness of the part |
Our machines are designed to form precise brake pistons and brake drums for safe and powerful brake systems. With brake pistons, our machines spin an all-round groove into the cylindrical hollow bodies. Brake drums are produced on our machines by flow forming, as far as possible in a single clamping setup.
Save brakes
Brake pistons
| Extremely low material input and optimum material utilisation | |
| Low post-processing requirements of end products | |
| Precisely dimensioned all round seal ring groove | |
| No reductions in course of wall thickness |
High performance brakes
Brake drums
| Rotationally symmetrical components with partially concave, convex, cylindrical or conical geometries | |
| Low weight and at the same time increased strength | |
| High-precision forming | |
| Low post-processing requirements |
Compared with the conventional process, pressing and welding, the spinning process enables a high cost reduction for the production of exhaust parts. A blank tube is spun by rollers rotating along the tube perimeter. With our innovative machines and technologies, a wide range of options are available to meet individual requirements.
Precise exhaust parts
Catalytic converter
| Variety of shape can be produced, such as oblique, concentric and eccentric parts | |
| During the process, the tube clamp section will not be applied with any centrifugal force as the tube does not rotate. This allows to process with a minimum clamping force, minimizing clamping scratch and possible material damage. | |
| As our process does not need dies inside the tube, it is possible to spin the tube with brick inside. |
Our necking-in and flow-forming machines are ideal for reliably forming sturdy tank vessels, bottoms and necks for hydrogen and liquefied gas. Both technologies stand for economic efficiency, short cycle times and high precision forming. The source material can be either aluminum or stainless steel. Our machines enable flexible forming in accordance with individual parameters.
Robust pressure vessels with neck and bottom
Liquid Gas Tanks, Pressure Tanks
| Gas-tight sealing of vessel bottoms | |
| Targeted increase of wall thickness in critical areas | |
| Homogeneous microstructure for maximum strength | |
| Sufficient material for cutting, drilling and thread machining |
Robust pressure vessels
Hydrogen Tank
| Considerable saving in material thanks to low raw material input | |
| Low post-processing requirements of end products | |
| Increased resistance to corrosion | |
| Maximum flexibility in the production of individual external diameters, wall thicknesses, and reductions |
