Estimating the term…
The invention relates to a method for producing veneered compressed parts, wherein a carrier preferably consisting of aluminum, an intermediate sheet of veneer and a cover sheet of veneer are glued together by exerting a pressure o over 200 M/cm2 at a temperature higher than 120° C. in a molding press as to form a unfinished molded part. The cover sheets of veneer and optionally the intermediate sheets of veneer are thoroughly dyed at an overpressure in an aqueous dye bath at a temperature ranging between 105 and 115° C. before executing the molding process and then dried while the surface of the finished molded part is lacquered. The production of the compressed part is substantially simplified when a continuous layer of a pasty, hardenable impregnating agent is applied on one side of the thoroughly dyed cover sheet of veneer and when the layer of impregnating agent is substantially prehardened while preserving flexibility. Post-hardening of the impregnating agent is carried out during the compression molding process at increased temperature. The cover sheets of veneer are stabilized mechanically as well as their color fastness by the layer of impregnating agent.
Process for production of veneered compressed parts, in which a carrier, at least an intermediate veneer and a cover sheet of veneer are adhered to each other under the exercise of a pressure of greater than 200 N/cm2 at a temperature of greater than 120° C. to form a preform part, wherein the cover sheet of veneer and optionally the intermediate veneer are prior to this subjected to an aqueous dye bath with over-pressure at a temperature of 105 to 115° C., are thoroughly dyed and then dried, and wherein the mold perform part is painted on its exposed surface, wherein on the thoroughly dyed cover sheet of veneer on one side a cohesive layer of a viscous, hardenable impregnation material is applied, wherein the impregnation agent layer is subsequently preliminary hardened with maintenance of its flexibility, and wherein the impregnation agent layer during the mold press process is finally hardened at an elevated temperature.
