1. Hand -painted sketch, and then use the drawing software to draw the sketch with accurate size to complete the initial design drawings.
2. Craftsman carving wax: Jewelry craftsman with reference to the drawing of the wax version, and then pour out the silver version with the method of casting the wax. This is the highest process in the jewelry production process. The silver version must be smooth and no trace, the structure is reasonable, and the position size of the inlaid gem is correct.
3. Plastic mold injection wax: After the rubber mold is good, start injecting the wax operation. The wax in the wax injection machine is kept at 70-75 degrees, the wax liquid is injected into the glue film, and the wax mold is taken out after cooling.
4. Select the stones: Select the right size and shape.
5. Pymal wax tree: Manually welded the wax ring to a wax rod to obtain a wax tree that resembles a large tree, preparing to cast it.
6. Calculating wax trees: The rubber chassis is weighted. After planting the wax trees, the weight of the wax tree is obtained. According to the density ratio of gold or silver, the amount of metal casting is obtained.
7. Slash gypsum: The stainless steel tube is covered with a good wax tree, and the corresponding weight gypsum pulp is slowly injected. Without the wax tree, it is naturally placed for 6-12 hours after being vacuum, so that the gypsum is slowly solidified.
8. Baking gypsum: Gypsum mold baking, the effect is dehydration, drying, casting insulation.
9. Take out the gypsum mold: Take it out and prepare the metal solution that needs to be cast at the same time.
10. Watering liquid gold: The melted gold water is injected from the water inlet.
11. Corporation of centrifugal process: Vacuum sensor centrifugal casting machine casting.
12. Gypsum mold frying and cleaning: After removing from the casting machine for 10-30 minutes, fry in cold water. After the gypsum is bursting, take out the golden tree, brush off the gypsum with steel, soak it in 30%of the hydrofluoric acid for 10 minutes, sandwiched and rinsed, and remove the remaining gypsum.
13. Cut the casting: Cut the golden tree's jewelry from the bottom of the water inlet and dry it.

15. Light process: All the light of the light is handmade, and the knife is repeatedly promoted on the surface of the jewelry.
16. Polishing process: polishing machine polishing to jewelry.
1. Concepts and design: Hand your own concepts to draw a sketch, and then use the drawing software to draw the sketch with accurate size to complete the initial design drawings.
2, craftsman carving wax: Jewelry craftsman with reference to the design drawings hand -carved a wax version, and then pour out the silver version with the method of losing wax casting. This is the highest process in the jewelry production process. The silver version of the silver must be smooth and non -trace, the structure of each part is reasonable, and the position size of the inlaid gem is accurate.
3, rubber mold injection: The rubber mold is opened and the waxing operation is performed. The wax in the wax injection machine should be kept between 70-75 degrees. The wax solution is injected into the glue film.
4. Select the stones: According to the silver version and wax mold, select the size, shape and color of the stones.
5, the wax type is finally completed: so the wax mold is made formed.
Hello, first use the glue mold to make wax molds, and then plant wax trees in batches, then inject gypsum, wait for the baking oven to bake until the wax is completely swinging.
