The craft card will not have a better three-dimensional effect, so some merchants have embossed on the thin precious metal to improve the visual effect, but the effect of embossing directly on the precious metal is not good, because when the precious metal is very When it is thin, it is more difficult to control the processing quality when making relief, and one side is raised, and the other side will be concave, which is not beautiful enough
If the precious metal is to be overmolded, the bulge will be easily suppressed, the relief effect will disappear, and the original idea will not be achieved.
However, if the precious metal foil is overmolded and then embossed, there will be a transparent phenomenon, that is, the other side is concave, which is not beautiful enough.

Embodiment Construction
[0028] 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.
[0029] The manufacturing method of this embodiment is used to make a precious metal craft card. The outer two layers are transparent plastic plates, and the inner layer is a noble metal foil. Such as figure 1 As shown, the manufacturing method of this embodiment includes a rolling step, a cutting step, a pattern pressing step, a plastic plate manufacturing step, a molding step and a hollowing out step. Among them, the rolling step, cutting step and pattern pressing step are carried out in sequence to process the precious metal foil. These three steps can be carried out simultaneously with the plastic plate production step to shorten the processing time. After the precious metal foil and the front and rear plastic plates are ready, the plastic step and th...

Abstract
Disclosed is a manufacturing method for a precious metal craft card. The method comprises: a rolling step: rolling a precious metal material into a foil piece (10) having a thickness of at least 1 μm; a cutting step: cutting the rolled foil piece (10) into a predetermined shape; a pattern pressing step: pressing a pattern on the cut foil piece (10) using a mould; a plastic plate manufacturing step: preparing a front plastic plate (31) and a back plastic plate (32), and pressing a bump with a predetermined height of 0.05 mm - 0.3 mm on the front plastic plate (31) and / or the back plastic plate (32) by a hot press, and then printing a coating on the inwards concave face of the bump; a laminating step: sandwiching the foil piece (10) between the front plastic plate (31) and the back plastic plate (32) with the bumps of the front plastic plate (31) and / or the back plastic plate (32) facing outward, and then placing the whole in a laminator for laminating; and a hollowing step: cutting the semi-finished product after the laminating into a partially hollowed shape.
Description
technical field [0001] The invention relates to precious metal crafts, in particular to a method for making a precious metal craft card. Background technique [0002] In today's society, it is very common to use precious metals to make handicrafts, such as precious metal stamps, precious metal paintings, precious metal postcards and so on. Due to the high price of precious metal itself, many precious metal handicrafts will make precious metals into extremely thin sheets to form craft cards to reduce the weight and price, which is suitable for promotion. The craft card will not have a better three-dimensional effect, so some merchants have embossed on the thin precious metal to improve the visual effect, but the effect of embossing directly on the precious metal is not good, because when the precious metal is very When it is thin, it is more difficult to control the processing quality when making reliefs, and one side is raised, and the other side is concave, which is not be...
