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.
