THE PRODUCTION OF SPECTACLE FRAME PARTS OF SYNTHETIC MATERIAL |
摘要 |
<p>The invention relates to the production of spectacle frame parts of synthetic material and in particular to the moulding of spectacle frame faces of synthetic material, for example, of polyurethane. The faces are moulded between two casting half-moulds each comprising a plate having an impression on one surface thereof. Each plate has a substantially equal thickness at every point and is made of a polyolefine. Use of such half-moulds enables the faces of spectacle frames to be directly moulded into their final shape.</p> |
