上記成形方法は、金属プレート2と、該金属プレートの一方の面に配置された熱可塑性樹脂3とを備える部品1を成形する方法であり、少なくとも配置工程と、固定工程と、成形工程とを有する。
本発明の成形方法の工程の一例を示す概略図を図1に示す。
上記金属プレート2は、プレス成形などにより所定の形状に成形され、金型4内に隙間なくぴったりはまるように成形されている。
したがって、熱可塑性樹脂3を所望の箇所のみに付与することができ、熱可塑性樹脂3が漏れることなく他の部品の金属面との接合領域を形成できる。
金属プレート2の周縁部を加熱することで、熱可塑性樹脂3の流動性が向上して周縁部まで行きわたり易くなって成形性が向上する。
例えば、アンモニア、ヒドラジン及び/又は水溶性アミン化合物の水溶液に浸漬する化学エッチングは、機械的な粗面化処理と異なり、開口径よりも内径が大きい孔が形成され、アンカー効果により、熱可塑性樹脂3と金属プレート2とを強固に接着できる。

熱可塑性樹脂3をせき止めて漏れを防止する支持部7aと、金属プレート2を固定する外側支持部7cとに分けることで、設計の自由度が高くなり、成形性が向上する。
当接部にエラストマー71を備えることで金属プレート2を傷つけることが防止される。加えて、金属プレート2の表面に凹凸がある場合であっても、支持部7aが金属プレート2に密着して金属プレート2を確実に固定し、熱可塑性樹脂3の漏れを防止できる。
上記固定型6の支持部7による押し当てと、可動型5側からの引張りにより上記金属プレート2の全面を可動型5に密着させることができ、部品1の寸法精度が向上する。
一般に熱可塑性樹脂は、金属プレート2の中央部から周縁部に向けて流動するため、周縁部では熱可塑性樹脂3が冷えて流動性が低下し易い。少なくとも上記金属プレート2の周縁部と当接する箇所に加熱装置を備え、金属プレート2を加熱することで、熱可塑性樹脂3の流動性が向上し成形性が向上する。
