Process for making pre-formed objects

摘要

Disclosed is a continuous line process for making a pre-formed object having a plurality of surfaces comprising the steps of: (1) providing a sol phase of the composition comprising a solvent and a gelling agent having a sol-gel transition point between about the melting point of the solvent and about the boiling point of the solvent; (2) forming surfaces of the sol phase composition by passing through a surface forming system, the surface forming system pressing the sol phase composition between a plurality of liners; (3) cooling the sol phase composition into a gel phase; and (4) cutting the gel phase composition; wherein the pre-formed object is free of a supporting substrate.
