Motor housings, batteries, fuel cells, rotors and stators – these are all comparatively large parts that are installed in both small vehicles and trucks. They have one thing in common: they must be securely bolted together. Unlike in other components in the vehicle, very long thin bolts are required, which are installed once through the entire width or height of a component. The previous manufacturing process limits the length of fasteners (regularly up to about 300 mm) and is inefficient for the production of this particular shape.

We have succeeded in developing a new manufacturing process which solves many of these problems. The result: Our product innovation KXpanded. The bolt head and the shaft are formed independently of each other and then press-fit stemed. This not only simplifies tooling and reduces delivery times. It also enables lengths of up to 600mm (which offer greater straightness as a further advantage) and bolt head sizes that are independent of the shaft.
