Method for the production of components coated with a decorative material

Abstract

A method for the blow molded production of double-walled components coated with a decorative material includes pressing an extruded plastic tube together with a decorative material into a component and simultaneously creating a pinched region on the component at the die separation region, placing the pinched region at a distance from the component side edge by displacing the die separation region, preferably with a slide, and, after the component is removed from the die, connecting a decorative material to the component around the side edge. Also provided is a blow molding die for performing the method. The die includes first and second die halves defining a die separation region therebetween, a slide disposed at the die separation region, movable in longitudinal and transverse directions with respect to the die separation region. The slide has an end face forming a portion of the inner contour that produces the edge region of the component, a first face bearing against the first die half and/or a projecting end of the decorative material, and a second face directed towards the second die half and forming with the second die half a pinching gap located away from the edge region of the component, the pinching gap forming the pinched region of the component and receiving a waste slug produced and detached at the pinched region.
