Abstract
Improved light reflector apparatus for use in an electronic flash unit or the like is formed by an injection molding operation, which causes both precise shaping of a reflector and accurate mounting of the reflector securely within a housing. A light-reflecting flexible sheet is placed in a mold so that its light-reflecting front surface is centrally positioned adjacent a mold forming surface. The forming surface, which is larger than the sheet, has a contour adapted for shaping the sheet to reflect light into a beam of illumination. Liquid plastic is injected into the mold under pressure against the opposite surface of the sheet, thus pressing its light-reflecting surface into intimate contact against the forming surface. Because the sheet is smaller, the border of the forming surface is not covered by the sheet. Plastic flows beyond outer edges of the sheet against the uncovered border of the forming surface. The intimate contact between the forming surface and the sheet blocks plastic from leaking therebetween onto the light-reflecting surface. The plastic solidifies to form a housing having a supporting body underlying the sheet and a shoulder, integral with the supporting body and contiguous with and surrounding outer edges of the sheet. The shoulder traps the sheet against the underlying supporting body for maintaining the contour of the sheet caused by the molding surface.
