Claims (1)
- ビレット収容キャビティとその下方の有底の成形キャビティとの間に絞り部を設けた成形型であって、ビレット収容キャビティの横断面の面積が成形キャビティの横断面の面積よりも大きく、絞り部が下窄まりのテーパー面に形成された内周面又は下窄まりの傾斜面に形成された相対向する内面を備えた成形型を使用し、この成形型のビレット収容キャビティに、結晶性の熱可塑性高分子材料を溶融成形したビレットを収容して、熱可塑性高分子材料のガラス転移点より高く溶融温度より低い結晶化温度でビレットを絞り部を通して成形キャビティに圧入充填し、成形キャビティの内面及び底面により背圧を与えて分子鎖又は結晶の配向状態と圧縮状態を維持したまま固定して得られる圧縮された成形体であって、
分子鎖又は結晶が実質的に成形体の軸又は軸を含む面に向かって斜めに配向しており、分子鎖又は結晶が成形体の軸に向かって斜めに配向した成形体は軸に垂直な横断面において分子鎖又は結晶が放射状の配列形態となっており、分子鎖又は結晶が成形体の軸を含む面に向かって斜めに配向した成形体は、成形体の軸に垂直な横断面において分子鎖又は結晶が平行な配列形態となっていることを特徴とする圧縮配向成形体。
