Abstract: The present invention is directed to a 4-bar kinematic link component and method for forming the 4-bar kinematic link using a single rotary molding tool. The invention eliminates the need to form individual components of the bracket from several different tools, which will then requires additional assembly steps. The 4-bar kinematic link is formed from two different materials each having a different in mold shrinkage value. This allows for hinge pins to be formed through a base component in a way that will prevent sticking of the components together thereby allowing the parts to have it relative to one another using the hinge pin. The final component is a 4-bar kinematic link that can be used as a 4 bar link mechanism for providing motion.
