Abstract
A method, molding device and vehicle component ( ) provide for minimized sink marks ( ) caused by structural ribs ( ) in the molding process. Molten material is injected into a first mold cavity to form a primary vehicle component part ( ) having structural ribs ( ) on a back side. Typically, sink marks ( ) may develop at a front surface of the primary vehicle component part ( ), located opposite to the structural ribs ( ) on the back side. Molten material is injected into a second molding cavity that is arranged to overmold the front surface ( ) of the primary vehicle component part ( ) and to cover sink marks ( ), if any, in the front surface ( ). In this manner, a vehicle component ( ) is manufactured with structural ribs ( ) and without visible sink marks ( ).
