Method for manufacturing metal hand tool

Abstract

A manufacturing method for metal hand tools comprises the following manufacturing steps: 1. A molding hand tool body is manufactured; 2. Color printing: color printing is carried out on a preset region of the surface of the tool body so as to form a printing layer; part of region in the range of the printing layer is designed to be fretwork shape; the position of the fretwork is a picture and text shape to be presented; 3. Plating: the surface of the hand tool body is plated; namely, a plating layer is formed on the surface of the hand tool body outside the printing layer and the surface of the position of the fretwork. The surface of the hand tool body manufactured according to the steps is provided with the printing layer. A fretwork picture and text part forming the picture and text shape is arranged in the range of the printing layer; and the surface of the fretwork picture and text part and the surface of the rest position of the hand tool body are provided with the plating layer; as the plating layer forming up the picture and text shape is arranged in the range of the color printing, the picture and text shape can be made to prominent; and as the hand tool body is molded, and then is printed on the surface, the paint can firmly attach on the rough surface of the metal and is difficult to drop off.

Description

technical field [0001] The invention belongs to the technical field of hand tools, in particular to a metal hand tool marked with pictures and texts on the surface. Background technique [0002] Hand tools such as sockets, fixed wrenches, adjustable wrenches, ratchet wrenches, screwdrivers... and other hand tools are tools that are often used in daily life. In order to highlight the product's trademark and product specifications, manufacturers will make graphics on metal hand tools logo. At present, there are two commonly used graphic and text marking methods. One is that when the hand tool is cast or forged, a protruding or recessed graphic and text mark is directly formed on the surface, and then electroplated after forming, but after electroplating, the entire hand tool is uniform. It is the same color, which cannot highlight the part of the graphic and text, so that the effect of the logo is not obvious. [0003] Another marking method is to electroplate the hand tool ...
