Abstract (en)
[origin: WO2014005848A1] The invention relates to an essential tool for a process in which an optically flawless window is produced from a semi-finished PMMA product. The invention especially relates to a novel vacuum forming process in which transparent plastic molded parts of particularly good optical quality can be produced from PMMA or PC at relatively low cycle times. Said molded parts are dimensionally stable and orthoscopic as they are removed from the mold. Furthermore, the transparent molded parts have no surface defects such as pimples.
