Abstract

　ベローズ状に溶融加圧成形され、少なくとも内面が鏡面のポリテトラフルオロエチレンよりなるベローズ。ベローズは、ポリテトラフルオロエチレンを円筒状若しくはビーカー状に予備成形したものか、または切削加工若しくはブロー成形されたポリテトラフルオロエチレンベローズの内側に中子を挿入し、例えば、特殊金型を用いて溶融圧着させ、中子を抜き出し、必要に応じ溶接することで得られる。特殊金型は複数個の可動外子金型、同数の後押し用外子金型からなり、外子金型と後押し用外子金型は交互に配置され、スライドしながら、それらの作る円を狭めることで成形物を溶融圧着させる。この後、外子金型と後押し用外子金型を外して、成形物を膨張させるとともに機械力を加えてフランジ部を拡張させて中子を取り出し、必要に応じ、溶接することでベローズが得られる。
