The production of a plastic molded part utilizes a barrier layer embedded in plastic. Plastic is injection-molded successively in different cavities of the injection mold onto a three-dimensional preform made from a cut of a multi-layer barrier film, which multi-layer barrier film comprises a barrier layer coated with plastic on both sides. The plastic coating of the barrier film cut is at least superficially melted by the injected plastic melt. And the preform is supported by a support formed on the corresponding partial mold on the respective opposite side.

Injection-molding machine

In a three-plate injection-molding machine comprising a nozzle plate, a movable second mold clamping plate, a movable end plate, a closing unit that acts between the end plate and the second mold clamping plate, and a turning unit arranged between the nozzle plate and the second mold clamping plate, rails extend between the nozzle plate and the end plate. The mold-half carrier of the turning unit is supported on a support structure so that it can be rotated about an axis transverse to the machine axis, which support structure forms the abutment for the mold-half carrier rotary drive. The weight of the support structure and mold-half carrier of the turning unit is transferred into the machine bed by means of linear guides, and a substantial part of the reaction torque applied to the support structure is transferred to one of the rails by means of one supporting guide.
