Description
「加熱軟化する平板状の第一部材からなる第一成形部と溶融樹脂が硬化した第二成形部とが一体成形されている複合成形品の製造方法であって、
型閉じにより成形空間が形成されると共に該成形空間に突出する堰部を有する成形型を型開きして、前記成形空間が形成される部位の一部に加熱軟化させた平板状の前記第一部材を配置し、型閉じに伴って立体的な前記第一成形部を形成すると同時に、前記堰部が前記第一成形部の周縁に設けられている厚さの薄い薄肉部に当接している状態にし、更に、前記堰部よりも外側で前記第一部材の周囲に形成されている前記成形空間の残りの部位に、射出された前記溶融樹脂を充填して、前記第一成形部と接する部位に接触させた後に硬化させて該第一成形部と接合している前記第二成形部を形成する」ことを特徴とする。
「前記成形型は、複合成形品の表面を形成する表型と裏面を形成する裏型とを有しており、
前記第一部材は、前記第二成形部が形成される領域へ延出する複数のタブを有しており、
該タブと前記表型との間に前記成形空間の一部が形成されるように、前記タブを前記裏型に位置決めした状態で型閉じする」ことを特徴とする。
