The principle behind the successful technology
Mechanical or hydraulic blanking and punching, as well as cold forming processes are flexibly combined to produce cost-effective components of a consistently high quality. Feintool has cutting-edge systems in place to efficiently handle the processes needed for the chipless forming of aluminum, standard or high-tensile steels using the fewest possible operations.
Cold forming enables complex part geometries to be manufactured without having to use additional mechanical processes. Targeted forming using multi-stage press tools can be used to create different wall thicknesses. Work hardening, which is linked with forming, ensures that products are functional and means that, depending on the material, subsequent heat treatment is no longer required. Every press stroke creates a part ready for assembly.
A million times proved
Every year, around 22 million high-precision parts are produced at Feintool’s forming locations in Germany and the US, primarily for the automobile industry. During these procedures, the focus is on the cold forming of steel.

Efficient production of high volumes
LIGHT, ROBUST AND EFFICIENT
The automobile industry has ambitious goals: lighter and more fuel-efficient vehicles, sturdier designs and more efficient production. Important optimization potentials lie in reducing the weight of the vehicle and in the drivetrain. The chipless forming process allows for the cost-effective production of lightweight, multifunctional components in industrial high-volume production. Formed components, such as planetary gear carriers and plate carriers, are essential for modern dual clutch, automatic and hybrid transmissions, for continuously variable transmissions and differentials. They help to reduce weight, ensure a more compact design and increase precision. Improvements in fuel consumption, reliability and gear shifting comfort of these drivetrain concepts are achieving significant gains.
COMPLEX DESIGNS IN A SINGLE OPERATION
Even complex designs can be produced in a single operation. The key: Feintool combines up to 14 individual tools to form a high-precision whole, covering operations such as deep drawing, milling and rolling. Not only are the forming presses precise, they offer very high output. They produce over 600 parts per hour – around the clock.
