Abstract

PURPOSE:To make a parting line invisible from the aspect of appearance and to facilitate color matching by forming a display part to the rear of a sheet-like body and subsequently applying drawing processing to the sheet-like body to bend the end edge thereof toward the rear and subsequently applying outsert molding to the rear. CONSTITUTION:When an operating panel 1 is prepared, color layers 3 of white, red and blue are printed on the rear of a sheet-like body 2 composed of a film to form display parts and hole parts 6 are formed to the sheet-like body 2 by punching processing to obtain the flat sheet-like body 2. Next, the sheet-like body 2 is placed on the die 10 of a mold so that the color layers 3 are turned toward the die 10 and a punch 9 and the die 10 are brought to a pressure contact state to form a bent part 8 and, thereafter, the sheet-like body 2 is released from the punch 9 and the die 10 to be mounted in an outsert mold. When the sheet-like body 2 having the bent part 8 is received in the space part 3 formed to the bonded surface of a cavity 11 and a core 12 and a molten synthetic resin 14 is injected in the space part 13, the molten synthetic resin 14 injected in a filling part 15 is applied to the rear of the sheet-like body 2 by outsert molding and solidified.

[Problems to be Solved by the Invention] By the way, the above-mentioned conventional technology uses a multi-color molding method, so it requires several types of injection molds, which increases the mold cost, and also requires illumination. It is difficult to adjust the thickness of the molding resin to match the color in order to prevent uneven illumination due to the distance from the lamp, and for example, when molding closed letters such as "P", due to the setting of the gate, the remaining part of the molded resin is difficult to match. The illumination condition becomes unclear and uneven.

[Operations] Since the colored portions are printed and formed by the above-mentioned means, multi-coloring is easy, color matching is also easy, and closed characters can be formed neatly. Furthermore, the mold is simpler than in the multi-color molding method, and mold costs can be reduced. Further, since the edge of the sheet-like body is bent toward the back side, no parting line appears, and the entire surface of the sheet-like body can be exposed for use.
