PURPOSE:To realize high rigidity, small thickness, and light weight, by forming a base body of material whose rigidity is higher than synthetic resin parts. CONSTITUTION:As a base body 1, an Al plate is formed in a tray type by press machining, then inserted into a movable metal mold and clamped. Resin is injected and a mold is opened after cooling, thereby obtaining a cabinet wherein the base body 1 of Al and parts 2 of ABS resin are formed in a unified body. The base body 1 is composed of metal containing aluminum. The parts 2 of synthetic resin is composed of aromatic polyamide(PA), polybutyrlene terephthalate(PBT), and acrylonitril butadien styrene(ABS). Hence external load and shock are supported by the base body 1, and heat dissipation of an internal circuit and an equipment is improved by using material excellent in thermal conductivity as the base body 1. Electromagnetic shield also can be added. Function imparting parts 2 like a boss and a rib are composed of synthetic resin, and therefore can be easily formed. |
