The invention provides a hardware stamping part surface treatment method. The hardware stamping part surface treatment method comprises the following steps that firstly, a hardware stamping part is immersed in aqueous alkali; secondly, the hardware stamping part is taken out of the aqueous alkali and then immersed in an emulsion degreasing agent; thirdly, alkaline matter on the surface of the hardware stamping part is removed through an acid solution so that the pH value of the surface of the hardware stamping part can be neutral; fourthly, the hardware stamping part treated in the third stepis immersed in a phosphating solution; fifthly, the hardware stamping part treated in the fourth step is rinsed through flowing clear water; sixthly, the hardware stamping part treated in the fifth step is dried; seventhly, molding powder is sprayed to the hardware stamping part treated in the sixth step; and eighthly, hot drying curing treatment is carried out on the hardware stamping part treated in the seventhly step. By means of the hardware stamping part surface treatment method, the damage to hardware can be reduced, water and electricity can be saved, and the washing time is short.
