Estimating the term…
A structural component such as a car door panel or door trim insert panel is produced in a single molding operation. For this purpose at least one premolded hard foam material block or member is inserted in a respective nesting mold cavity. Then an intermediate fiber material layer preferably in fleece form is placed on top of the foam material block. Then, a surface cover layer, such as a layer with a decorative exterior surface is placed on the intermediate fiber material layer with the decorative surface facing an upper mold section. The mold is then closed and the necessary heat and molding pressure are applied to laminate the intermediate fiber material layer to the cover layer. Then a nesting die applies additional pressure to the hard foam block for bonding the hard foam block to the intermediate fiber material layer. Depending on the selection of materials, an adhesive layer may be used between the fiber material layer and the cover layer and/or the fiber material layer and the hard foam block which serves as an impact absorbing reinforcement of the finished product.
A method for producing a laminated structural component having impact protection features, in a mold having an upper mold section and a lower mold section, said lower mold section including at least one nesting mold cavity with a respective nesting die in said nesting mold cavity, said structural component including a decorative surface cover layer, an intermediate fiber material layer, and at least one hard foam member, comprising the following steps:
