Abstract
(EN)
Thermoplastic forming tools and assemblages are provided for forming thermoplastic components. In particular, thermoplastic forming tools and assemblages are provided for forming thermoplastic components having precision micro-scale features and reproducible macro-scale dimensions. The thermoplastic forming assemblages can include at least a bottom tool and a top tool having a rigid tool body and an elastomer layer conformally coating at least a portion of both rigid tool bodies. The bottom and top tool can be so dimensioned that, when in the closed position, they define a cavity forming the thermoplastic component. The rigid tool bodies provide the reproducible macro-scale dimensions in the thermoplastic component, while the elastomer layers form and release the precision micro-scale features in the thermoplastic component when formed. Tool-forming structures are also provided for making thermoplastic forming tools and assemblages, as well as methods of making the thermoplastic forming tools, and methods of use for forming thermoplastic components.

L'invention concerne des outils et assemblages de façonnage de thermoplastiques pour façonner des éléments thermoplastiques. En particulier, l'invention concerne des outils et des assemblages de façonnage de thermoplastiques pour former des éléments thermoplastiques présentant des caractéristiques de précision à l'échelle microscopique et des dimensions reproductibles à l'échelle macroscopique. Les assemblages de façonnage de thermoplastiques peuvent comprendre au moins un outil inférieur et un outil supérieur présentant un corps d'outil rigide et une couche élastomère recouvrant de manière conforme au moins une partie des deux corps d'outil rigides. L'outil inférieur et l'outil supérieur peuvent être dimensionnés de telle sorte que, lorsqu'ils sont en position fermée, ils définissent une cavité formant l'élément thermoplastique. Les corps d'outil rigides fournissent les dimensions reproductibles à l'échelle macroscopique dans l'élément thermoplastique, tandis que les couches élastomères forment et libèrent les caractéristiques de précision à l'échelle microscopique dans l'élément thermoplastique lorsqu'il est façonné. L'invention concerne également des structures de façonnage d'outil pour fabriquer des outils et des assemblages de façonnage de thermoplastiques, ainsi que des procédés de fabrication des outils de façonnage de thermoplastiques et des procédés d'utilisation pour façonner des éléments thermoplastiques.
