Abstract: A hinge has a central element and a surrounding element. One of the central element and the surrounding element is formed by injection molding, and the other element is then formed on the priorly-formed element by injection molding such that a limit segment is mounted around the neck segment having a smallest outer width of the central element, which keeps the surrounding element from departing from the central element, and further simplifies a structure of the hinge. Because a melting point of the element formed priorly is higher than a melting point of the element formed later, the element formed later does not attach to the element formed priorly, and the two elements are relatively rotatable. Finally, because the manufacture of the hinge is accomplished after injection molding twice, the process of manufacturing the hinge is more convenient, faster and lowers the cost.
