Abstract

　成形品間でのゴムと超高分子量ポリエチレンとの接着性のバラツキを減少させる生産効率のよい超高分子量ポリエチレンとゴムとの複合成形方法を提供する。 　ゴムにゴム用補強材と加硫剤とを配合して形成した未加硫ゴムコンパウンド31を、固定金型部11と、少なくとも一部が可動である可動金型部14とからなる射出成形金型内の所定位置21にインサートし、可動金型部14の可動部13を動かして最終成形品の体積よりも大きくした前記射出成形金型内の成形キャビティ内22に超高分子量ポリエチレン32を射出し、次いで射出成形金型内の成形キャビティが目的とする最終成形品の体積になるように可動金型部の可動部13を動かして圧縮成形し、前記射出成形金型から当該成形品を取り出して加温し、ゴムコンパウンド部分を加硫状態にする複合成形方法。
