Described herein is an automatic or automated process for injection molding of coated components, more particularly coated soles of plastic, where first of all the molding tool is lined with a release agent composition and, after flashing of this release agent composition, a composition for forming the component is injected. After crosslinking of these two compositions, the coated component produced is removed from the molding tool and subjected optionally to an aftertreatment.
