Claims6
An insert-molded article comprising a metal component and a resin component,
- the metal component having a shape including a flat plate-shaped part, the flat plate-shaped part having a through-hole or a blind hole formed therein,
- the resin component having a shape including a covering part that covers a surface of the flat plate-shaped part, the covering part having a surface in which a gate mark is present, wherein
- the through-hole or the blind hole formed in the flat plate-shaped part of the metal component is located opposite to the gate mark, and
- the resin component has a filler part with which the through-hole or the blind hole is filled.
A method for producing an insert-molded article including a metal component and a resin component,
- the metal component having a shape including a flat plate-shaped part, the flat plate-shaped part having a through-hole or a blind hole formed therein,
- the resin component having a shape including a covering part that covers a surface of the flat plate-shaped part,
- the method using an injection mold having a pin gate as a gate,
- the method comprising:
- opening the mold, and setting the metal component as an insert article on the mold so that the through-hole or the blind hole is opposed to the pin gate;
- and
- closing the mold, and injecting a molten molding resin material from the pin gate to form the resin component through injection molding.
