Abstract
A metal design panel is constituted by a surface decorative member and a thermoplastic resin member, which are firmly and integrally combined together. A plurality of through holes or dimples are formed at prescribed positions of a metal plate panel, which serves as a surface decorative member, in conformity with an outline of a product completed in manufacture. The metal plate panel is subjected to trimming to remove an unwanted peripheral portion, thus extracting a metal plate therefrom. The metal plate is arranged in a metal mold, into which a melted thermoplastic resin is injected to form a resin layer, which is firmly combined with the metal plate. Alternatively, a core member is formed and extracted from the metal plate panel and is combined with a resin layer upon injection molding.
Claims7
A manufacturing method for a metal design panel comprising:
- forming a plurality of through holes at prescribed positions of a metal plate panel, which serves as a surface decorative member, the prescribed positions being continuous around a periphery of a product completed in manufacture;
- trimming the metal plate panel to remove a peripheral portion, thus extracting a metal plate having the plurality of through holes continuous around the periphery of the metal plate;
- and
- injecting a thermoplastic resin into a metal mold in which the metal plate is arranged, thus forming a resin layer firmly combined with the metal plate.
A manufacturing method for a metal design panel comprising:
- forming a plurality of dimples at prescribed positions of a metal plate panel, which serves as a surface decorative member, the prescribed positions being continuous around a periphery of a product completed in manufacture;
- trimming the metal plate panel to remove a peripheral portion, thus extracting a metal plate having the plurality of dimples continuous around the periphery of the metal plate;
- and
- injecting a thermoplastic resin into a metal mold in which the metal plate is arranged, thus forming a resin layer firmly combined with the metal plate.
A manufacturing method for a metal design panel comprising the steps of:
- molding and trimming a metal plate panel, which serves as a surface decorative member, to form a core member, which is then cut out from the metal plate panel;
- fixing a holding member onto an interior wall of the core member by adhesion or by welding;
- and
- injecting a thermoplastic resin into an interior space of the core member, thus encapsulating the holding member in a resin layer, which is firmly combined with the core member.
A manufacturing method for a metal design panel comprising the steps of:
- molding and trimming a metal plate panel, which serves as a surface decorative member, to form a core member, which is then cut out from the metal plate panel and which is integrally accompanied with a plurality of projecting elements;
- inwardly bending the plurality of projecting elements relative to the core member;
- and
- injecting a thermoplastic resin into an interior space of the core member, thus embedding the projecting elements in a resin layer, which is firmly combined with the core member.
