Jewelry processing technology and detailed illustrations of the entire production process

In fact, what we saw Each piece of jewelry is soul-infused by designers and manufacturers, and their creation requires very complicated craftsmanship. Below we will introduce you to the entire process of a diamond ring from design to finished product.

1. Concept and design: The designer draws a sketch of his own idea by hand, and then uses drawing software to draw the sketch on a computer with precise dimensions to complete the initial design drawings.

Artisan carving wax: jewelry craftsman The wax plate is hand-carved according to the design drawings, and then the silver plate is poured out using the lost wax casting method. The mass production of the wax plate requires the use of a silver plate to press a rubber mold. This is the most demanding process in the jewelry making process. The silver plate must be smooth and traceless, the structure of each part must be reasonable, and the position and size of the inlaid gemstones must be accurate.

Wax injection into the rubber mold: After the rubber mold is opened, the wax injection operation is carried out. The wax in the wax injection machine should be kept between 70-75 degrees, and the wax liquid is injected into the glue. film, take out the wax mold after cooling, and repeat in sequence to obtain multiple wax molds.

Select matching stones: According to silver Patterns and wax models, and select matching stones of suitable size, shape and color.

Complete wax model: ready All wax plates required for this batch production.

Planting wax trees: Each wax ring is individually hand-welded to a wax stick, resulting in a wax tree shaped like a large tree, ready for casting.

Weigh the wax tree: Weigh the rubber chassis before planting the wax tree, and after planting the wax The tree is weighed again, and the weight of the wax tree is calculated by subtracting the two weighings. The weight of the wax tree is converted according to the density ratio of gold or silver to determine the amount of metal to be cast.

Gypsum filling: Plant well Put the wax tree and the base plate into a stainless steel cylinder, and slowly inject the corresponding weight of gypsum slurry along the inner wall of the steel cylinder to cover the wax tree. After vacuuming, it will naturally stay for 6-12 hours to allow the gypsum to solidify.

Baking plaster: Place the plaster mold Baking is used for dewaxing, drying and casting heat preservation.

Take out the plaster mold: Take out the baked plaster mold and prepare the metal solution to be cast.

Pouring liquid gold: will have Melt the prepared gold water and pour it into the water port.

Centrifugal casting: using vacuum Casting by induction centrifugal casting machine.

Gypsum mold blasting and cleaning: The cast gypsum mold is in a high temperature state. After being taken out from the casting machine, leave it naturally for 10-30 minutes, and then put it into cold water for blasting and cleaning. After the gypsum bursts due to shrinkage, take out the golden tree, brush off large pieces of gypsum with a steel brush, soak it in 30% hydrofluoric acid for 10 minutes, clamp it out and rinse to remove the remaining gypsum until the surface of the golden tree is clean.

Cut the casting: cut the gold The jewelry from the tree is cut out along the bottom of the spout and left to dry.

Roller polishing process: stainless steel Abrasives and active organic synthetic solutions are put into the drum and rubbed with rotation to make the surface smooth and bright.

Calendering process: Calendering is all done by hand, using a special calendering knife to push back and forth on the surface of the jewelry. This process requires certain techniques and techniques.

Polishing process: use polishing machine Polish the jewelry until the surface is smooth, smooth and bright.

Selecting diamonds: hand-cut diamonds Sorting, picking out the ones that match the color, cut, and size, and prepare them for inlay.

Inlaid diamonds: each set by hand A diamond.

Quality control: The finished jewelry will be carefully inspected one by one to ensure qualified quality.
