Demystifying the whole process of making alloy jewelry

The origin of ornaments was originally used to cover the body, and later with the improvement of people's living standards, it slowly evolved into decoration-oriented products. Alloy jewelry is used to decorate and wear. Good jewelry can play the role of fragrance, cleaning and beautification. Now almost everyone owns accessories, from hairpins and earrings to bracelets and bracelets. Of course, because of price and other factors, alloy jewelry is more popular. So how are these beautiful and colorful alloy jewelry produced? Here is a detailed introduction to the production process and craftsmanship of alloy jewelry. 1. To produce a piece of jewelry, if we don't have pictures or samples, we need the designer to collect the data and draw it on the plane drawing. After that, the pattern maker needs to use alloy materials to make three-dimensional masters according to the requirements of the drawings. 2. If we have a sample or have produced it before, we don't need to make a plate, but can directly enter the second step of the compression mold. The first step: plate making The following engraving machine is the plate making machine. Step 2: Revision After the alloy is carved by the precision engraving machine, our plate maker will then need to review and revise the template. Step 3: Compression Mold Production of alloy jewelry requires a mold. Compression mold is the key to mass production of single jewelry. The quality of the compression mold will directly affect the yield of the next process. The physical properties of special rubbers are very special. They are quite soft and have good plasticity during compression molding, but after a certain temperature change, they will be formed into a mold with a certain strength and a higher melting point than the alloy. The fourth step: during sand foundry 'sand castingParting agent, put on the sand box, fill the sand box, compact and smooth, turn the upper sand box 180 degrees, take out the upper and lower halves respectively, and then turn the upper mold 180 degrees and close the lower mold. , Waiting for pouring. This set of craftsmanship is commonly known as 'Furnishing'. After sanding, trim the formed alloy material to remove large burrs! The following is the fifth step of the sand-finishing machine and the alloy formed after sand-finding: Although the large burrs have been removed from the alloy material after polishing and trimming, the surface smoothness is far from reaching the surface bright process requirements of jewelry. Therefore, the blisters of the alloy material must be removed through the polishing process. Step 6: Welding After the alloy jewelry is processed, some accessories such as chains, clips and springs must be connected or welded. This is an important link in the combination of ornamental decoration and functionality. For example, the ear pins on the ear studs, because of the different materials, can only be welded on the link and cannot be found by sanding. After the welding is finished, we have to inspect these semi-finished products, and the qualified ones will be sent to the electroplating workshop for electroplating. Step 7: Electroplating The dazzling artificial jewelry we have seen are all electroplated. There are also many kinds of plating colors, such as gold plating, silver plating, copper plating, nickel plating and white steel plating are more common plating colors. Step 8: Point drilling and packaging. Some of the electroplated jewelry can be packaged directly, but some need to be drilled according to the design. Point drilling is already the last step in the production process of alloy jewelry. Usually the diamonds used for point drilling are rhinestones, which are glued on with an adhesive and can be arranged in various patterns by design. After ordering the diamond, you can ask colleagues in the packaging group to pack this piece of golden jewelry! These are all the production processes of alloy jewelry, and a set of such processes can produce those beautiful jewelry. How is it, does it feel amazing?
