Abstract
A blow molding part with a decorative coating is produced in a three-stage process. The blow molding part is initially produced without a coating in a blow mold tool cavity, and is then molded against the decorative coating material in a second blow-molding operation under low pressure and at a low temperature in a decorative coating cavity. The decorative coating material is heated up if appropriate and is placed in advance against a mold contour. The blow mold tool includes a middle part, which is provided between two movable side parts and can be moved or pivoted out. Mold contours of the middle part form with the mold contours of the side parts the blow mold tool cavity and the decorative coating cavity. The blow mold tool cavity has holding devices for the blow molding part. The decorative coating cavity has suction openings and heating elements for molding the decorative coating material and heating it up.
