Abstract
A composite board has a vacuum molded surface plate (12) and a bottom plate (13). Edges of the surface plate (12) and the bottom plate (13) are fixed into one piece by thermoplastic fixation, and a top wall of each supporting protrusion (135) and a body of the surface plate (12) are fixed into one piece by thermoplastic fixation. The composite board is formed by superimposing at least two layers of boards. A method for manufacturing the composite board provides process guidance for manufacturing the composite board.
Claims15
A household article comprising a composite board, wherein the composite board comprises:
- a surface plate (12) comprising a plate-like surface plate body (122);
- a bottom plate (13) comprising a plate-like bottom plate body (133) arranged at a bottom side of the surface plate body (122), opposed to the surface plate body and spaced apart from the surface plate body with a certain distance, and a plurality of supporting protrusions (135) protruding from the bottom plate body toward the surface plate body (122),
- wherein the surface plate (12) and the bottom plate (13) are respectively formed by vacuum molding, peripheral edges of the surface plate (12) and the bottom plate (13) are formed as one piece by thermoplastic fixation, and at least a portion of a top wall of each of the supporting protrusions (135) and the surface plate body (122) are also formed as one piece by thermoplastic fixation.
A method for manufacturing the household article comprising the steps of:
- heating a surface plate blank (52) and a bottom plate blank (51);
- placing the surface plate blank (52) at a top side of a surface plate mold (63), placing the bottom plate blank (51) at a bottom side of a bottom plate mold (62), and combined molding the surface plate blank and the bottom plate blank by vacuum molding process, respectively;
- fixing the surface plate blank and the bottom plate blank together by thermoplastic fixation.
