The invention relates to a manufacture method of a diaphragm or a filter plate, with low cost and high precision. When a larger die cavity space is left between an upper die and a lower die used for manufacturing the diaphragm or the filter plate, plastics in molten state in an infection machine charging barrel is quantitatively injected into the large die cavity formed by the upper die and the lower die of the die cavity under low pressure through the flow passage in the upper die or the lower die. Then, the periphery of the upper die and the lower die are treated with complete die-closing in closed state under the action of external force, and after the diaphragm or the filter plate in the die cavity is cooled down, the die is opened and the diaphragm or the filter plate is taken out. The method has the advantages that not only the plasticized plastics in the plastic diaphragm cavity are homogeneously extruded to every part of the cavity to be shaped, but also the low-pressure injection molding of the plastics diaphragm is realized and the demand for the mold locking tonnage of a press is reduced, therefore, resource waste and energy consumption are avoided. The method can be suitable not only for thermoplastics and thermosetting plastics, but also for plastic alloy, blending material, recycled thermoplastics, and the like, therefore, the regeneration and reutilization of the resources can be realized.
