SHAPED ARTICLE MADE OF BRITTLE MATERIAL, ENCAPSULATED IN AN INJECTION-MOULDED PLASTIC HOLDING FRAME, AND METHOD FOR ENCAPSULATING THE SHAPED ARTICLE WITH THE HOLDING FRAME |
摘要 |
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. |
