ABSTRACT:
An inkjet printhead lid has a light opacity component and a laser light transparent component molded together in two shots in an injection molding chamber. The laser light transparency component has a periphery that extends beyond a periphery of the light opacity component on substantially all sides thereof. An inkjet printhead body laser welds to the laser light transparency component in an area between the peripheries of the two lid components. Inkjet printers for containing the printhead are also disclosed. In the molding chamber, two sources of injection molding materials inject a first and then a second mold to mold the two lid components together. One of the two sources of injection molding materials has laser light transparency characteristics while the other has light opacity characteristics. Mechanical interlocking features may also exist in both of the two lid components.
