| 摘要 |
Particular embodiments of the invention include methods and apparatus for molding and/or curing an article. Particular embodiments of such methods include positioning a mold core centrally within mold outer portion to form an annular mold cavity between the mold outer portion and the mold core, the core including an outer ring having an outer surface for engaging the annular article, the outer ring being formed of a material capable of expanding and contracting with changes in temperature. Such methods also include heating the mold outer ring, cooling the core outer ring subsequent to the step of heating, whereby the core outer ring contracts relative to the article, and removing the article from the core outer ring. |
