Abstract

<P>PROBLEM TO BE SOLVED: To provide a method of surface printing and electroplating which hardly cause peeling by rubbing. <P>SOLUTION: A pre-plating layer is formed on the surface of a metal or a non-metal product to be plated after pre-plating at first to prevent the oxidation of the surface and next, ink printing is carried out and further electroplating is carried out on a non-printed part to be higher than the height of the printing layer. As a result, oily ink printing is protected by the plating layer to hardly cause the peeling by rubbing. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to surface printing and electroplating methods, and more particularly to a completely new preplating process in which a pre-plated layer is first formed on a metal or non-metal surface and then electroplated.

  Electroplating metal products for surface decoration is a commonly used industrial technical technique. Due to the effect of electroplating, the surface is only a single color and another plating layer is usually printed to enhance the aesthetic or advertising effect with the font and drawings.

  Such conventional methods of printing and electroplating first electroplate on a metal surface and then print with oil ink; the formed electroprinted layer is embossed on the electroplated surface. It is peeled off just by being rubbed by something foreign or hard.

  When performing the method of first electroplating on a metal surface and then printing with oil ink, the metal surface must be pre-cleaned; the metal surface is oxidized during the printing phase, which means that Not visible to the naked eye, so the product advantage is low after electroplating; oil ink prints are peeled off and plated even when rust prevention or antioxidants are applied during the electroplating process Product inferiority occurs.

  In addition, in the plating for obtaining the effect of the three-layer thickness, for example, in the manufacture of a chest drop medal, the metal material is corroded with an acid, and thereafter, an oil ink is applied and then processed by electroplating. Although the effect of the three-layer thickness can be obtained by this process aspect, it is difficult to manufacture a product having an irregular shape (for example, one manufactured by bending an elastic steel plate), and the effect of the three-layer thickness is received. Is impossible.

  In view of the above problems of conventional methods, the inventors of the present invention provide surface printing and electroplating methods.

  The method first pre-plats to form a pre-plated layer on the metal or non-metal surface to be plated so that the metal or non-metal surface is not oxidized and is printed and then electroplated. And the electroplating layer is made higher than the electroprinting layer, thus resulting in a three layer thickness effect, and oil ink printing is protected by the plating layer, thus eliminating the tendency to rub off.

  The metal of the metal pre-plated layer according to the present invention can be nickel, semi-bright nickel, copper, or the like.

  Furthermore, the surface printing and electroplating method of the present invention provides a three layer thickness effect in the production of parts having atypical shapes.

After reading the detailed description of the preferred embodiment of the present invention with reference to the accompanying drawings, the flow and effects of the manufacturing process of the present invention will become apparent.

Referring to FIG. 1, which shows a flowchart of a method for surface printing and electroplating according to the present invention, the present invention includes the following steps:
1. Supplying a product to be plated, which is metallic or non-metallic,
2. First, pre-plating to form a pre-plated metal layer on the surface of the product to be plated, thereby pre-plating so that the surface of the product to be plated is not oxidized and acid corrosion is not required;
3. Printing a non-conductive oil ink on a partial surface of the pre-plated metal layer to form an electroprint layer;
4). Electroplating the unprinted portion of the metal of the pre-plated metal layer to form an electroplated layer, so that the thickness of the plated layer is greater than the thickness of the electroprinted layer, Electroplating step.

  The pre-plated metal layer can be nickel, semi-bright nickel, copper, or the like, thereby preventing oxidation of the electroplated metal or non-metal. On the other hand, the electroplated metal material can be copper or iron.

  Referring to FIG. 2, which shows an irregularly shaped product made by the method of the present invention; this product is made by bending an elastic steel plate, on which an electroplating layer 4 and an electroprinting layer 3 are formed. .

  FIG. 3 is an enlarged cross-sectional view showing a part of FIG. 2. A metal product 1 to be plated has a metal pre-plated layer 2, and a partial surface of the metal pre-plated layer 2 is printed so Then, electroplating is performed, and the electroplating layer 4 becomes higher than the electroprinting layer 3. Here, the electroplating surface obtains the effect of the three-layer thickness of the printed pattern, and the electroprinting layer 3 by oil ink Is protected in the electroplating layer 4 and is less likely to be peeled off by rubbing, thus surpassing the prior art.

In conclusion, according to the description disclosed above, the surface printing and electroplating method of the present invention includes basic elements for granting a patent, newly claimed by the applicant, and according to a Japanese patent. Request protection.

2 is a flowchart of the present invention. Product made by the method of the present invention. FIG. 3 is an enlarged cross-sectional view showing a portion of FIG. 2.
