A method may include inserting a pin into a pin hole defined in a boss insert, and introducing the boss insert to a mold cavity defined in a mold plate of a mold assembly. The method further includes flowing chain link substrate to the mold cavity, and cooling the chain link substrate such that a chain link is formed. The chain link includes a base portion, a platform extending from the base portion, and a rib assembly extending from the platform and including a plurality of ribs and defining a central pocket. The boss insert is disposed in the pocket, and the pin is disposed in the pin hole of the boss insert.
