Patent ID: 7524389

Claim:
Process for producing a composite body part for a motor vehicle in a tool which comprises a first tool part and a second tool part which are movable relative to one another and which together form a mold cavity, comprising the steps of: inserting an outer skin into the first tool part with a peripheral edge of the outer skin spaced inward of a peripheral edge portion of the mold cavity defined by the first tool part, and placing at least part of a peripheral edge area of a side of the outer skin facing the first tool part that is located inward of said peripheral edge into sealing contact with a seal arrangement comprising a pair of seals formed of a permanently elastic material which is provided in the first tool part, producing a negative pressure between the first tool part and the outer skin in the area between the pair of seals of the seal arrangement so as to produce said sealing contact of the outer skin with the seal arrangement, applying a plastic material to a side of the outer skin which faces away from the first tool part and extending within the mold cavity beyond and around said peripheral edge, shaping the plastic material by applying pressure by means of the second tool part, and releasing the composite body part produced from the seal arrangement by applying positive pressure between the pair of seals and removing it from the tool.
