Abstract
A method of producing a vehicle interior panel having a hollow double-walled structure made of thermoplastic comprising, blow molding with a pair of mold halves including a first mold with a shape transfer surface having a three dimensional pattern, and a second mold, clamping a cover material being formed by at least a double-layer structure arranged between a cavity of said first mold and a parison of thermoplastic such that a resin sheet layer without a through hole and without a three dimensional pattern faces a cavity of said first mold, introducing a pressurized fluid into the parison to press the cover material and the parison against a cavity surface, thereby integrally laminating said cover material to an outer surface of a first wall of the panel having the hollow double-walled structure and transferring said three dimensional pattern of said first mold half to said resin sheet.
