The invention discloses a molding and manufacturing process for a hinge, and aims at providing a molding and manufacturing process, wherein the molding and manufacturing process meets the demands of production and manufacture of a drop-shape cylindrical hinge, improves the utilization rate of raw materials, guarantees the mechanical performances of the produced hinge, and meets the requirements for high strength. The main points of the technical scheme are that the process comprises the following steps: A, cutting fed materials, i.e., employing a cutter to cut a metal rod serving as a raw material into metal segments with a specific standard; B, cold-heading shaping, i.e., employing a cold-heading machine for enabling the metal segments formed at the step Ato form drop-shape cylindrical structures in a cold-heading manner; C, cold-heading stretching, i.e., enabling the metal segments formed at the step B to form installation connecting holes in a cold-heading manner; D, cold-heading leveling, i.e., enabling the metal segments formed at the step C to form connecting end faces in a cold-heading manner; E, cold-heading chamfering, i.e., enabling the metal segments formed at the step D to form guide chamfers in a cold-heading manner. The process employs a method of cold heading to form the drop-shape cylindrical hinge, improves the production efficiency of an enterprise, and reduces the production cost.
