Abstract

1322377 Injection moulding PROJECTEURS CIBIE 31 July 1970 [5 Aug 1969] 37103/70 Heading B5A [Also in Division F4] A headlamp reflector is made by stamping out a sheet metal casing 2, injection moulding a layer 3 of thermoplastic material on to the interior of the casing 2, and applying a reflective coating 4 to the free surface of the layer 3. The thermoplastic material is injected into the space between the casing 2 and an appropriately shaped die (not shown).
