Description
1)液体冷却用の入口および出口だけを残して、マニホルドを、傾斜磁場コイルシステムと共に樹脂に封入することができる。
2)入口及び出口の接続を大地電位に維持して、操作者の安全及び装置の小型化を図ることができる。
3)冷却回路を、従来の装置よりも早い段階で完成しテストすることができる。
4)より少ない密封点を備えた閉じた金型を、樹脂含浸用に使用することができる。これは金型アセンブリの樹脂浸透用に最適の角度に向けさせることを可能にする。
5)樹脂含浸後に装着又は交換すべきホースはなく、従って仕上げ作業を大幅に削減できる。
6)従来のマニホルドが露出していた空間を真空含浸させることができ、したがってコイル構造を頑丈にすることができる。
