Net-shape geometry

A net shape geometry is produced to its required final contour during the actual manufacturing process itself. In cold extrusion, this means that no additional machining is subsequently required to produce the contour for the geometry in question.

Depending on the component, features such as diameters, steps, bores, flange geometries, profiles, undercuts and other geometric elements can be produced directly through the forming process. Technical feasibility depends on the specific geometry, the material, and the required tolerances and surface finishes.

If geometries can be produced directly through cold forming, subsequent machining steps can be reduced or avoided. This can reduce processing time, material waste and production costs. This can represent a significant economic advantage, particularly for high production volumes.

No. ‘Net-shape’ refers primarily to the geometry produced directly during the manufacturing process. Depending on the component, subsequent processes such as heat treatment, coating, cleaning and inspection, or the machining of individual additional features may be required.

As part of its technical manufacturability analysis, MN Kaltformteile considers, amongst other things, component geometry, material, tolerances and surface finish requirements. The aim is to produce as many geometric features as possible through cold forming alone and to reduce additional processing steps to the minimum technically necessary.
