Embodiment 1
[0032] Embodiment 1: as figure 1 As shown, a 3D hard gold process, the steps include: S1, making a master and cleaning; S2, using the master made in step S1 to make an adhesive film, and using the adhesive film to make a wax plate that can replicate the shape of the master Model, and repair; S3, apply silver oil to the wax model, hang the wax model on the workpiece fixing frame of the electroforming cylinder, so that the wax model rotates with the workpiece fixing frame during the electroforming process; S4, start the electroforming cylinder Carry out electroforming to obtain an electroforming part; S5, remove wax from the electroforming part, remove wax, fry color, and remove impurities; S6, perform mold-holding process, sandblasting process and calendering process on the semi-finished jewelry piece in step E in sequence.
[0033] Among them, the steps of making a master in S1 are as follows: S11, making 3D model data through computer software; S12, importing the prepared 3D ...
