Embodiment Construction

[0019] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

[0020] The first embodiment The method for making a planar embossed precious metal card includes a foil making step, an engraving step, a transfer printing step, a color printing step and a plastic overmolding step.

[0021] Step (1) is a foil manufacturing step. Gold or silver is used as the raw material of precious metals, and rolling is carried out multiple times—rough rolling, intermediate rolling, and finishing rolling, and finally rolled into foils with a thickness of 0.004mm-0.01mm. Stress relief annealing is required after each rolling to avoid stress concentration and damage. After the foil rolling is completed, it needs to be cut according to the predetermined size. After cutting, it is put into the hydraulic press and the design pattern is pre...

Abstract

The invention relates to a method of manufacturing planar relief noble metal cards. The method includes the following steps: 1) rolling and cutting noble metal raw materials to form foils, and performing oil pressing onto the surface of the foils to form design patterns; 2) performing fine sculpture on a shaping surface of a mold by means of a laser machine according to the design patterns, thus forming design patterns having 3D effect on the shaping surface of the mold; 3) press-printing a cold ironing film onto the shaping surface of the mold having the 3D effect, and performing cold ironingtransferring onto surface of a photographic film or the noble metal foil, wherein the 3D effect is formed on the position of the cold ironing film on the photographic film or the noble metal foil andcorresponding positions of the design patterns; 4) performing color printing to the corresponding positions of the design patterns on the cold ironing film; 5) laminating the photographic film and the foil and performing mould shaping. In the method, the shaping surface of the mold is sculptured and the cold ironing film covers the mold, then the cold ironing film is transferred onto the photographic film and the foil, so that the planar relief 3D effect is formed on the surface of the noble metal card. The method can improve vision effect of the cards, satisfies user demands and has advantages on market promotion.

Description

technical field [0001] The invention relates to a technology for making precious metal handicrafts, in particular to a method for making plane embossed precious metal cards. Background technique [0002] In today's society, precious metals are highly collectible substances, and various jewelry and handicrafts made of precious metals are more and more popular. Precious metal sheet handicrafts, such as cards or banknotes, are one of the types of precious metal handicrafts. Because of their thin thickness and simple shape, the purchase threshold is low and the market potential is great. The surface of common precious metal cards is usually oil-pressed with shiny patterns, and there are few precious metal cards with embossed 3D effects on the market, which need to be developed. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art, and provide a method for making a plane embossed precious metal card, so that the sur...
