Shaped articles made of brittle material having a low coefficient of thermal expansion, for example designed as glass or glass-ceramic plates, are typically encapsulated with a holding frame made of plastic, which is produced by directly encapsulating the edges of the shaped article with plastic by injection moulding. In order to avoid stress concentrations in the shaped article, which inevitably form as a consequence of the differences in thermal expansion and the material-dependent shrinkage behaviour, according to the invention shrinkage-absorbing elements are embedded between the holding frame and the shaped article, which elements additionally ensure a permanently elastic bearing of the shaped articles when used in practice and provide sufficient sealing during use.
Articles profilés d'un matériau fragile, ayant un faible coefficient d'expansion thermique et prenant la forme, notamment, de plaques de verre ou de plaques vitrocéramiques. Ces articles sont habituellement encapsulés dans un cadre de fixation en plastique, obtenu en encapsulant directement les bords de l'article profilé avec du plastique grâce au moulage par injection. Afin d'éviter une concentration de contraintes sur l'article profilé, qui se produit inévitablement en raison des différences au niveau de l'expansion thermique et de la contraction dépendant du matériau, des éléments absorbants sont enchâssés entre le cadre de fixation et l'article profilé. Ces éléments agissent en outre, dans la pratique, comme appuis élastiques permanents des articles profilés, et fournissent un scellage approprié durant l'utilisation.
