Abstract

The iridescent plastic contains a random dispersion of translucent coloured fragments. In injection moulding, the elements tend to separate, producing streaks of uniform colour and destroying the random effect. For this reason, such frame have, till now, been cut from solid block. A moulding method is used in which there are injection inlets for each half of the frame, the lens openings being cut out from the finished moulding. The injection openings are pref. sited so that any streakiness runs transversely to the lens rims, i.e., does not follow the lens contours. The cutting after moulding may be confined to the lens openings or may extend to other parts of the frame also.
