Abstract

PURPOSE:To obtain the titled molded product without core offset, falling or the like obtained by plastically deforming a metal insert having an inner diameter larger than a necessary dimension during resin molding by molding pressure or the like to form a highly precise inner diameter dimension by a sizing pin inlaid in the hollow part of the insert. CONSTITUTION:In using a bearing 1 made of a sintered alloy or the like as a metal insert having a hollow part and injecting a resin 2 such as a thermosetting resin (e.g.; an epoxy resin or the like) or a thermoplastic resin to mold the same, the inner diameter of the insert is preliminarily made larger than a necessary dimension and the bearing 1 is mounted into a metal mold in a condition inlaying a sizing pin 3 in said bearing and a resin 2 is injected from a gate 4 to apply molding pressure P1 to the bearing from outer periphery thereof as well as to plastically deform the bearing 1 to make the inner diameter of the bearing 1 same to the outer diameter dimension of the sizing pin 3. In this case, in order to facilitate the fitting of the insert inner diameter to the sizing pin 3, cut-in parts 5 can be provided to said inner diameter.
