    摘要: Thermosetting polymer is introduced into a mold at one end thereof to fill said mold. After a predetermined length of time to permit the thermosetting polymer to polymerize along the wall of the mold to form a wall of the desired thickness, gas is introduced into said mold at the opposite end to eject the central unpolymerized portion of the thermosetting polymer from the mold, leaving behind in the mold a hollow formed article.
