Abstract:
A process for fabricating a part made of a molding material, by means of a molding cycle having a duration of &tgr; per part to be molded, said process comprising the steps of:a. providing tooling having a thermal diffusivity of &agr;, a mold surface and an internal heat transfer channel through said tooling, said channel being spaced from said mold surface a distance less than twice (&agr;&tgr;)Â½; b. providing said molding material to said tooling so that it contacts said mold surface; c. providing heat transfer fluid to said heat transfer channel to facilitate exchange of thermal energy between said tooling and said fluid during said molding cycle; and d. removing from said tooling at a time interval of &tgr;, a formed part.
