Embodiment Construction

[0046] The invention discloses a 3D hard gold production process. The process can accelerate the electroforming speed and simultaneously improve the uniformity and purity of the electroforming layer.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0048] In a specific embodiment of the present invention, the 3D hard gold production process includes the following steps:

[0049] S1: Make a master.

[0050] The master plate is located in the electroplating bath of the electroplating cylinde...

Abstract

The invention discloses a 3D hard gold production process, comprising: making a master plate; cleaning the master plate; ensuring that the gold content of the electroforming liquid in the electroforming cylinder is greater than a set value; hanging the master plate on the swing of the electroforming cylinder On the piece, the master plate rotates with the swing piece during the electroforming process; after the electroforming is completed, the cylinder is lifted, and the wax port is removed on the electroforming piece; water milling; wax removal, acid frying, and impurity removal. In the 3D hard gold production process of the present invention, before the master plate is put into the cylinder, the master plate is cleaned, thereby avoiding the mixing of impurities into the electroforming layer and improving the purity of the electroforming layer. In addition, in the 3D hard gold process of the present invention, sufficient electroforming liquid is ensured in the electroforming cylinder before electroforming, thereby improving the uniformity of the electroforming part. Secondly, in the process of electroforming, the master plate rotates with the rocker, which not only accelerates the speed of electroforming, but also further improves the uniformity of electroforming.

Description

technical field [0001] The invention relates to the field of 3D hard gold, and more specifically, relates to a 3D hard gold production process. Background technique [0002] 3D hard gold is mainly produced by electroforming. Put the master plate in the electroforming cylinder, and as the electroforming proceeds, an electroformed layer is formed on the master plate, which is the 3D hard gold layer, and finally the master plate is taken out to form 3D hard gold. However, in the production process of 3D hard gold, there are disadvantages of long electroforming time and uneven electroforming layer. In addition, impurities carried on the master will affect the purity of 3D hard gold. [0003] Therefore, how to design a 3D hard gold production process that can accelerate the electroforming speed and improve the uniformity and purity of the electroforming layer is a key problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The purpose of...
