DEFINITION

Classification: 264/299

(under subclass 239) Processes in which (1) fluent or plastic material is caused to flow to assume the configuration of a solid shaping surface in contact therewith, or (2) solid material is forced against a shaping surface by pressure means opposed thereto.

(1) Note. Vulcanizing between pressure surfaces or in a shape retaining cavity is considered to involved "mold shaping" for the purpose of this subclass and those indented hereunder.
