Patent ID: 7244117

Claim:
An injection molding apparatus comprising: a molten resin injector for injecting a molten resin; and a die in communication with said molten resin injector, so as to enable injection of molten resin into the die, the die comprising: (a) a cavity having a prescribed shape formed in said die, said cavity comprising: (i) a perfectly filling part in communication with said molten resin injector, so as enable the perfectly filling part to be perfectly filled with the molten resin, and (ii) an imperfect filling permissible part in communication with the perfectly filling part, so as to permit molten resin to flow from the perfectly filling part into the imperfect filling permissible part and imperfectly fill the imperfect filling permissible part, and (b) an opening in communication with said cavity, wherein, during injection molding using the injection molding apparatus, a molding object is compressed onto said die at a molding object bonding surface, adjacent the opening of the cavity, so as to block the opening of the cavity and define a surface of a solidified resin member formed during injection molding, said molten resin being closely adhered to said molding object by injecting said compressed molten resin into said die, and allowing a solidified resin member to be formed by allowing said molten resin to solidify and adhere to the bonding surface of said molding object.
