What is the production process of jade bracelets?

1. Interpretation of raw materials

The first element in making a bracelet is to clearly understand the performance of the raw materials, determine the type of finished product and the selling point of the product, is it the highlighting color? Or kind? This will determine the direction of the next step of cutting.

This can be said to be the most important step in all processes, and even the step that determines success or failure. If you lack experience and skills and cut in the wrong direction, the result will be a waste of resources, which is a pity. This is what distinguishes an expert from an average processor.

2. Measure and draw the bracelet ring

Its importance is mainly reflected in the quality and quantity of the output. On the cut jade slices, the size of the raw material and the distribution of color are used to determine the size of the bracelet to be made, so as to achieve the best color distribution and the highest output, which is the optimal result. At this step, the designer's understanding of the texture of the original stone, the market value of the bracelet and design experience are tested. Only people with a high sense of responsibility and a calm mind can undertake such an important step. Therefore, it is better to say that it is measuring the designer's skill rather than drawing a bracelet on a piece of jade.

3. Absorbing the ectoembryo

After drawing the bracelet ring, the jade plate should be fixed on a special diamond drill lathe. According to the size of the outer ring of the bracelet, a diamond drill bit of the same size should be matched. Then, the whole bracelet should be sucked out by pressing down the drill. This is called "sucking the outer embryo".

4. Check the bracelet cake

This is a crucial step in quality assurance. Check and examine whether the sucked-out outer blank meets the original design intention and whether there is any deviation. Half of it comes from the judgment of human negligence and has nothing to do with experience and responsibility, such as the assessment of the impact of cracks; the other half of the reasons are due to unforeseen defects such as color changes, impurities, cracks, etc. in the raw materials. When these problems occur, they must be solved before proceeding to the next step.

5. Sucking Endoderma

Adjust the size of the drill bit according to the size of the inner ring of the bracelet, fix the sucked out outer embryo, press down the drill suction, and drill out the inner ring of jade. This is called "sucking the inner embryo", and the inner embryo is also commonly known as the "bracelet core". After this step, we have obtained a simple rough bracelet.

6. Topping

This step can be explained in two steps: one is to carve out the size of the bracelet rough blank according to needs; the other is to remove defects and cracks from the rough blank.

7. Edge

It means removing the sharp edges of the bracelet and polishing it until it is smooth.

8. Chong Dajiao

It means grinding arc angles on the inner and outer surfaces of the flat and smooth bracelet blank according to the different needs of round and flat bars. The curvature angles of the inner and outer circles of a round and flat bracelet are different. The outer circle of a flat bracelet is flat and the inner circle is flat, while the inner and outer circles of a round bracelet are cylindrical, so the angle and strength of the impact angle are different.

9. Punching embryos

According to the needs, round bracelets and flat bracelets are used to figure out the prototype of the outer surface of the bracelet. Compared with the traditional fully manual blank punching method and the blank punching method using shaping machines on the market, the former is suitable for high-end bracelets, while the latter is suitable for mid- and low-end bracelets.

10. Polishing

Including wood nest and dew, refers to the complete shaping of the inside and outside of the rough bracelet after the blank is punched. Punching the blank is just to grind out the curvature angles of the inner and outer circles of the bracelet. The surface of the bracelet after punching is not the forming surface of the bracelet. It still has many traces of arcs left by the previous processes. Womulushui’s task is to grind these traces of arcs from coarse to fine into a smooth surface.

11. Polishing

It means removing sand and polishing the finished bracelet to show the luster of the jade bracelet. The polishing should be done from the outside to the inside, back and forth several times until each jade bracelet reaches the desired brightness.
