Craftwork in plastic-sealed three-dimensional shape, and manufacturing method of craftwork

Abstract

The invention relates to a craftwork in a plastic-sealed three-dimensional shape, and a manufacturing method of the craftwork. The craftwork is a dish, a bowl, a spoon or a cup, and comprises two films and one precious metallic foil sheet which are adhesive to each other and jointly molded by hot pressing and bending, wherein the two films are consistent in shape and size; the shape of each film is consistent with that of the craftwork; the foil sheet is arranged between the two films; the shape of the foil sheet is consistent with that of the craftwork; an adhesive layer used for enabling the foil sheet and each film to be fixedly connected is clamped between the foil sheet and the corresponding film, and each adhesive layer and the foil sheet are consistent in shape and area; each adhesive layer is a film with glue or a hot melt adhesive layer; and the surface of the craftwork is smooth or is provided with embosses. The craftwork disclosed by the invention has the advantages that precious metal gram weight can be greatly reduced, and besides, the quality problem of a formed three-dimensional shape, which influences the rate of finished products, can be avoided; and manufacturing cost is reduced, and purchasing threshold is reduced, so that market promotion is facilitated.

Description

technical field [0001] The invention relates to a precious metal handicraft, in particular to a plastic-encapsulated three-dimensional handicraft and a manufacturing method thereof. 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, precious metal plates, precious metal bowls, precious metal cups and so on. Due to the high price of the precious metal itself, the existing three-dimensional precious metal handicrafts are all made of precious metal sheets, the thickness of which is relatively thick, and the weight of the entire precious metal handicraft is relatively large, the cost is relatively high, and the purchase threshold is high. Thin, although the cost of raw materials is reduced (precious metal weight is small), but when the ultra-thin foil is stamped into a three-dimensional shape, it is prone to wrinkles and cracks, which se...

Problems solved by technology

Due to the high price of precious metals, the existing three-dimensional shaped precious metal handicrafts are all made of precious metal sheets, the thickness of which is relatively thick, and the weight of the entire precious metal handicraft is relatively large, the cost is relatively high, and the purchase threshold is high. Thin, although the cost of raw materials is reduced (precious metal weight is small), but when the ultra-thin foil is stamped into a three-dimensional shape, it is prone to wrinkles and cracks, which seriously affects the product yield and is not conducive to mass production. It needs to be improved
