Description

Nickel plate manufacturing process Technical Field The application relates to the technical field of steel plate electroplating, in particular to a nickel plate manufacturing process. Background In the field of light guide plate manufacturing, a nickel plate has excellent hardness, wear resistance and forming stability, so that the nickel plate is a core mold base material for realizing high-precision dot reproduction on the surface of the light guide plate, and the quality of the nickel plate directly determines the light emitting uniformity and optical performance of the light guide plate. At present, as the smoothness of the steel plate is high, the main preparation mode of the nickel plate is an electroplating forming process based on the steel plate, namely, a preset net point structure is firstly processed on the surface of the steel plate in a manner of collision points through external collision equipment, then a nickel layer is attached to the steel plate through electroplating, net point forms are etched again, finally the nickel layer is stripped to obtain the nickel plate for the die, and the end face of the nickel plate has a convex net point structure. For the above process, when the steel plate is bumped, zinc oxide in the steel plate may be bumped out, and poor products such as spots may be formed on the surface of the steel plate, which may cause surface defects in the nickel layer plated on the surface of the steel plate, that is, in the nickel plate, and non-lattice concave and convex may occur on both end surfaces of the nickel plate, eventually leading to low yield of the light guide plate manufactured based on the nickel plate.
