Abstract: A manufacturing method for a hinge has steps of forming one of a central element and a surrounding element by injection molding, cooling down the formed element, and forming the other element on the priorly-formed element by injection molding such that a limit segment of the surrounding element is mounted around the neck segment, which keeps the surrounding element from departing axially 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. Therefore, the two elements are relatively rotatable. Finally, because a manufacturing process is accomplished after injection molding twice, the process is more convenient and faster, and the cost is lowered.
