Under the action of electrolysis, a metal electroforming layer is gradually deposited on the surface of the product, the product is taken out from the solution after reaching the required thickness, and in the electroforming process, the edge parts of the first shell and the second shell are connected together without secondary electric welding or repair welding.

Step (4), performing gold-holding press polishing, and polishing a finished product to enable the surface of the product body to be more neat and beautiful;

step (5), cleaning and polishing the product, cleaning and drying the surface of the product, and putting the product into a product tray;

further, in the step (1), three sets of molds are provided for molding the first shell, the second shell and the inner bead, each set of mold comprises a male mold and a female mold, the male mold and the female mold surround a mold cavity space, wherein the mold cavity space of the first set of mold corresponds to the shape of the first shell, the mold cavity space of the second set of mold corresponds to the shape of the second shell, the shape of the third set of mold corresponds to the shape of the inner bead, the three sets of molds are filled with a product molding material, and are cooled and molded to obtain the first shell, the second shell and the inner bead of the product, wherein the first shell and the second shell surround a shell structure of the hollow bead, and the first shell and the second shell are respectively provided with a hollow hole and a perforation.

The hollow bead forming process has the beneficial effects that: the first shell and the second shell are connected into a whole by adopting an electroforming process, so that the hollow bead shell is formed, extra electric welding and repair welding are not needed, the interfaces of the first shell and the second shell are complete, the appearance of a product is effectively guaranteed, the aesthetic feeling of the product is improved, the value of the product is improved, the practicability is high, and the popularization significance is high.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 2, the present invention provides a hollow bead forming process for forming a hollow bead, wherein the hollow bead includes an outer shell 10 and an inner bead 20 disposed inside the outer shell 10, the outer shell 10 is disposed in a spherical shape, the outer shell 10 is hollow, a hollow hole 14 is disposed on an outer surface of the outer shell 10, the hollow hole 14 extends from the outer surface of the outer shell 10 to inside of the outer shell 10, through holes 13 are disposed on two sides of the outer shell 10, the through holes 13 on the two sides are disposed oppositely, a through hole 21 passing through in a transverse direction is disposed on the inner bead 20, when in use, an external chain body simultaneously passes through the through hole 13 of the outer shell 10 and the through hole 21 of the inner bead 20, and the through chain body connects a plurality of hollow beads, so as to form a chain bead structure, and thus the chain bead can be worn.
