Eletroforming processing method for K gold jewellery

Abstract

The invention relates to the technical field of jewellery processing, and specifically relates to an eletroforming processing method for K gold jewellery. The eletroforming processing method for the K gold jewellery comprises the following steps: pouring a melted low-melting-point alloy into a die, carrying out cooling forming on the low-melting-point alloy, and then removing the die to obtain a blank body composed of the low-melting-point alloy; eletroforming a K gold layer on the outer surface of the blank body to obtain a jewellery prototype; punching convection holes in the jewellery prototype; boiling the jewellery prototype punched with the convection holes, melting the low-melting-point alloy and enabling the low-melting-point alloy to flow out from the convection holes; then filling and sealing the convection holes in the surface of the jewellery prototype by virtue of a sealing wax; and carrying out surface treatment on the jewellery prototype with the filled-sealed convection holes to obtain finished jewellery. The eletroforming processing method for the K gold jewellery is capable of producing the hollow K gold jewellery, and the weight and the content of the K gold jewellery are effectively lowered, so that the K gold jewellery can be conveniently worn by a user, the production cost is greatly lowered, and the competitiveness of the product is effectively improved; and moreover, a fund demand on manufacturers is lowered, so that the development of the manufacturers is benefited.

Description

technical field [0001] The invention relates to the technical field of jewelry processing, in particular to an electroforming method for K gold jewelry. Background technique [0002] K gold is an alloy made of gold and other metals. The existing K gold manufacturing technology adopts the inverted molding process, that is, it is produced by the inverted molding process of molten gold casting. The products produced by the casting are all solid products, and their weight is relatively heavy. When the jewelry is large in size, it is extremely inconvenient. It is only suitable for light and simple styles or inlaid styles. Since K gold mainly uses gold as the main raw material, a solid K gold jewelry is not much cheaper than pure gold jewelry in terms of labor costs. A large backlog of funds and cost burdens have been caused, which is not conducive to the development of various manufacturers. Contents of the invention [0003] In order to overcome the above defects, the objec...
