Production process for 165-mesh ultrafine electroformed nickel meshes

The invention discloses a production process for 165-mesh ultrafine electroformed nickel meshes. The production process comprises the following steps: (1) preparing a nickel mesh die; (2) carrying out primary nickelage; (3) carrying out secondary nickelage, wherein in the three steps, nickelage is required to be performed in an electrolyte, and the electrolyte is nickel sulfate with a concentration of 380-480-g/L; the step (3) is completed in a secondary plating tank, in the process of feeding a mesh, the whole mesh is synchronously fed, in the process of nickelage, the temperature is controlled at 55-65 DEG C, the plating of meshes is performed by using a single-cathode tube, and the two ends of the single-cathode tube are respectively provided with integral titanium blue as an anode. Nickel meshes produced according to the process disclosed by the invention are large in open porosity and uniform in opening; holes of meshes are in the shape of an outward horn, so that pulp is discharged more uniformly when t
