Abstract

The subject invention relates to a method of molding an automotive front lamp assembly that prevents the formation of a sink on the reflector by cutting an area into an injection molding tool so that when the reflector is molded, a glare prevention feature is formed in approximately the same location as the sink would have been formed.

Claims (10)

1. A method of molding an automotive front lamp assembly reflector comprising the steps of:

a. providing an injection molding tool;

b. determining where at least one sink will form on a reflector;

c. cutting an area into the injection molding tool that corresponds to the location of the at least one sink on the first reflector in order to create at least one glare prevention feature; and

d. molding with the injection molding tool, that has the area cut into it, the reflector, so that the at least one glare prevention feature forms on the reflector in approximately the same location as the at least one sink would have formed.

2. The method of molding an automotive front lamp assembly reflector of claim 1 wherein the reflector comprises a thermoplastic reflector.

3. The method of molding an automotive front lamp assembly reflector of claim 1 , wherein the at least one glare prevention feature comprises a rib with a convex surface having a sharp radius.

4. The method of molding an automotive front lamp assembly reflector of claim 1 , wherein the at least one glare prevention feature comprises a half-sphere having a sharp radius.

5. The method of molding an automotive front lamp assembly reflector of claim 1 , wherein the at least one glare prevention feature comprises a rib with a substantially perpendicular surface to the reflector and a curved surface.

6. The method of molding an automotive front lamp assembly reflector of claim 1 , wherein the at least one glare prevention feature comprises a rib with a substantially perpendicular surface to the reflector and an angled surface.
