The present invention relates to a method for manufacturing a pole product having a hologram processing pattern, and more particularly, to form a hologram pattern such as spin, hairline or wave pattern directly on the pole product during electroforming. However, the present invention relates to a method of manufacturing a pole product having a hologram processing pattern so that the hologram pattern can be formed to a certain depth and pursuit of workability and efficiency.

Generally speaking, electroforming products are made by electroforming, that is, electrodepositing metals such as nickel (Ni), chromium (Cr), or copper (Cu) on a model board to which a peeling film is applied. It refers to the manufacturing by the processing method to separate the electrodeposited metal from the model plate to obtain a product having the irregularities of the surface of the model plate.

And, hologram means to express an image reproduced by light in a space where nothing exists, and it is a medium to give aesthetics to the expression of an aesthetic technique or to convey information appealing to human beings. It is used in various fields such as electronic products or credit cards.

This hologram has excellent visual advertisement effect, so the hologram technique is applied to the above-mentioned Jeonju products, and various shapes are expressed by interference of light by applying various holograms to the feeling of flat metallic. By making it possible, they are pursuing aesthetic expressions such as adding luxury or subtle feelings.

 However, according to the manufacture of electric pole products having a holographic processing pattern according to the prior art, since the surface of the pole plate made of nickel, chromium or copper material made of electric poles is not in the same linear plane but has a variation in thickness, When directly processing a hologram pattern such as spin (rotary mesh) or hairline (straight stripe) on the main disk, there was a problem in that the pattern depth such as spin or hairline was formed inconsistently.

Therefore, the holographic pattern is not directly processed on the electroplate, but the surface of the electroplate is cut with diamond bites before the hologram pattern is processed, and the holograms such as spin or hairline are processed, but this method is also difficult to form a constant hologram. There was this following issue.

The present invention has been made in view of the above-described problems, and its object is to allow a hologram pattern such as spin, hairline or wave pattern to be directly formed on a pole product during electroforming. Not only to produce the electric pole product with the holographic processing pattern, but also to make the hologram pattern on the electric pole product with a certain depth, and to produce the replicated hologram electric pole product by using the produced electric pole product as a model plate. In addition, to provide a method of manufacturing a pole pole product having a hologram processing pattern to improve the processability and production efficiency of hologram processing on the pole pole product as a whole.

The present invention for achieving the above object is provided with a base plate and forming an insertion groove in the center by the pitting process; Comprising a step of providing a holographic processing disc in the shape and size corresponding to the insertion groove of the base plate; Fixing the hologram disk into the insertion groove of the base plate to complete a first model plate; Polishing the upper surface of the first model plate as a whole and performing a plane processing; Forming an embossed hologram pattern on the hologram processing disc of the first model plate through NC or CNC machining; Impregnating a first model plate (M1) on which the embossed hologram pattern is processed into a release chemical bath and forming a release coating on a surface thereof; Forming a metal electrodeposition layer on the surface after the first model plate coated with the release coating film is impregnated into an electrolytic cell; Peeling a metal electrodeposition layer from the first model plate to obtain an intaglio holographic electroplating plate having a holographic processing pattern oppositely concave by the machining surface of the holographic processing disc; After providing the second model plate using the intaglio holographic electroplating plate obtained in the above step, the release film forming step and the metal electrodeposition step are performed again to form a holographic processing pattern which is reversed by the surface of the intaglio holographic electroplating plate. Obtaining an embossed holographic electroplate; It is characterized in that the technical configuration consisting of the steps of mass-producing the intaglio and embossed replica hologram pole plate using the intaglio holographic pole plate and the embossed hologram pole plate.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
