Abstract
A shaping tool includes a membrane made of a polymer material, the membrane having a shaping surface, and a thermalization system inserted into the membrane. Moreover, a method for constructing a membrane of a shaping tool includes providing a mold with a shape of the membrane to be made and a polymer material that constitutes the membrane; pouring the material into the mold; cross-linking the material; providing a thermalization device and providing a device for increasing thermal conductivity.
Claims23
A shaping tool comprising a flexible membrane made of a polymer material, said flexible membrane being deformable to a desired curvature for glass shaping and having a shaping surface, and a thermalization means comprising at least one deformable conduit traversing said flexible membrane according to a profile of the flexible membrane.
