摘要： A method for precisely controlling the volume of a product such as a tire tread or tire that is placed into a mold is provided. This method includes providing a tread or tire that is built upon a portable mold core by laying a series of layers on the portable mold core. The outer diameter of the lire tread or lire is initially built to be purposely smaller than the interior surfaced of the mold in order to prevent any interference from occurring between the mold and the tire tread once the tire tread and core are placed within the mold and the mold is closed. The weight of the tire tread or tire is measured to see if the volume of the tire tread or tire is within acceptable parameters to fit within the mold. If not, additional material is added to the tire or tire tread.

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.
