Selective chroming

A final injection molded assembly and process for making same that eliminates paint and reduces areas of wasted chrome material. The final injection molded assembly has at least one first injection molded part of a non-plateable first material, at least one overmolded part of plateable second material, at least one pathway through the assembly and integrated features operable for selectively applying an electric current. The pathway creates a predetermined surface path arrangement for applying chrome to desired predetermined plateable areas. A shot of each material is delivered to an injection molding rotary device to produce the injection molded assembly which is then affixed to a chroming process line where electric current is applied. As the electric current is applied and chrome is delivered only the plateable second material will accept the chrome.
