Abstract

A housing component, for the production of a housing of a multi-shaft screw machine, includes a base body, in which at least two bores interpenetrating each other are configured. The bores extend in a conveying direction through the base body and are limited transversely to the conveying direction by an inner wall. The inner wall configures at least one first wall section and at least one second wall section such that the at least one first wall section is harder than the at least one second wall section. The wall sections, for example, are generated by material application. The housing component allows for a reliable wear protection and a positive influence on the material processing.
