Weight reduction is a top criterion for e-mobility. At the same time, high fatigue strength is required. The solution for both requirements is shot peening. Shot peening compensates for material savings or the use of lighter materials - for example when switching from steel to aluminum. It significantly increases the service life and dynamic strength of components. KST shot peening technology uses shot peening for a wide range of products from automotive suppliers. For example, for springs, steering knuckles, gear wheels, connecting elements and similar components subject to fatigue loading.
High dynamic fatigue strength
Durability is a risk factor and therefore a decisive aspect, especially for components subject to dynamic loads. Shot peening makes components significantly more resilient, even in lightweight construction. Millions of balls of rounded wire grains hit the surface at high speed and generate residual compressive stresses in layers close to the surface on impact. The work hardening gives components the required dynamic fatigue strength and resistance - despite their lower weight.
"Problem solver for e-mobility"
"This stabilization effect makes shot peening a reliable problem solver for e-mobility," emphasizes KST Managing Director Marco Heinemann. The service provider runs individual test series for customers as required in order to achieve predictable results. This allows developers to take the positive effects of shot peening into account as early as the design phase and reduce the component weight accordingly.
For rack goods, bulk goods and individual parts
The surface specialists blast rack goods, bulk goods and individual parts on different types of systems. For very delicate products, barrel blast machines ensure 100% batch reliability. They guarantee single-variety processing even of very small components. In general, a component length of up to around 200 millimetres is possible for metallic bulk goods.
