Any jewelry casting to hold mode to repair, plastic, necessary polishing. In addition to the jewelry components cannot cast are combined, and make it complete, such as welding Bracelet all active interfaces, brooch manufacturing hanging nose and welding, stud earrings, ear of the stamping production,

The casting jewelry components scattered into complete jewelry and other work is done in the model in order.

Tens of thousands of jewelry processing factory jewelry casting need repair, shaping,polishing and combined artificial one by one. Apparently they die this process requires a large number of workers, large jewelry processing factory they die personnelproportion should be about 80%. Each of the model workers need to be equipped withthe modular addition

Bench work, they die must jewelry tools, such as crane (all kinds of milling cutter,including supporting grinding needle, drill, steel brush), welding torch, a hammer,scissors, a file (also known as Luo Ju) can be used to grind jewelry ring, withcolumnar, pear shaped milling cutter, can be used to grind jewelry outside,

Umbrella, a cutter for milling, grinding, drilling to drilling concave vacuum bead needleclaw used to grinding mosaic. Crane also can be equipped with a variety of grindingbrush, such as blankets, cotton, silk cashmere brush brush brush, copper wire brush,steel wire brush, polishing brush, which has its own purpose. Wire brush and copper wire brush

To wear jewelry appearance or remove the dirt, and blanket wool brush, brush, brushthe skin silk used to polish jewelry.

Jewelry they die is also an important process, jewelry casting they die bad will directly affect the quality of the jewelry, such as the emergence of rabbet is not positive, floralasymmetry coordination, the surface is not smooth, and even left the rasp mark.Obviously this procedure on the die working requirement is relatively high, especially

Workers need more they die workers, they have high technology, training is moredifficult, the need is divided into teams and workshop, a foreman at any time to checkthe mould quality. They die workers must master the following skills to manufacturequalified and exquisite jewelry inlaid

Jewelry.

1, crane is they die process using the most one of the tools of jewelry, jewelry is the most useful tool. First they die workers must master the use of crane, know they diecrane must match what cutter (Luo Ju) and its application. To understand the internal structure of the electric hoist

The main parts of machine, snake, crane head shaft and gear shift pedal forreplacement and maintenance. The lifting machine skillfully complete grinding, drilling,cutting and polishing, etc..

2, the file is also used a jewelry tools most die. With the burr, file file jewelry blankwelds and file out of plane or concave and rough machining than by Crane fast, andlifting machine grinding is performed in the file after machining, this will speed up theefficiency of the die

. So the correct use of file is hold basic technology model workers must grasp, to be able to skillfully use a variety of file repair jewelry casting plane, arc, rosettes and light side. Even less leave file marks on the finished jewelry on the surface of the work piece as far as possible, such fine play in jewelry

The grinding and polishing are easy, it can not only improve efficiency, but alsoimprove the quality of.

3, the use of the bow according to often have to die in the process, such as the nozzlein the jewelry casting will bow saw sawed off, to expand or shrink ring ring also needhacksaw, so they die workers should master the hacksaw used, only saw off a piece of wire or a metal sheet is not enough

, should also be able to use freely saw saw various patterns and geometric cut the metal plate.

Tiny defect 4, jewelry casting needs repair, jewelry. (bracelet connected) will need to be combined, ring ring port restructuring and casting surface blowhole repair workcannot do without welding process. Obviously, the welding technology is the jewelry making the most basic and the most important skill. Welding

The connection to the hands and feet. In general, the operator hand good tweezersclamping the workpiece, holding the torch hand, foot to keep treading wind ball (bag)to gasoline vaporizing oil can squeeze into torch, torch flame can be adjusted, smallstrong flame as welding

Then, the coarse flame to workpiece annealing. Metal debris can smelting residue.

5, the hammer in the mold is very frequent. Hammer using the seemingly simple, butthe hammer in the jewelry processing using not easily on the surface of the workpieceto leave traces, this will give the processing stage (such as grinding, polishing and other) difficulties. Ring ring

Mouth slightly smaller required in the ring with a hammer to hit, the need to gentlycrush with a hammer, still can not be too hard, otherwise it might cut ring. Good command of using hammer strength is a must for the model workers.

6, for they die workers the most important requirement is to should have certain aesthetic ability. We should know what kind of jewelry styles generous fashion, its arabbet is regular. How to make jewelry dressing more exquisite and beautiful. How tomaximize the performance of jewelry inlaid precious stones

Beauty, if they die out of the jewelry bad not crooked, surface rough, they die the workers themselves did not recognize these problems, which will seriously affect the quality of the jewelry. The above is the most basic technology they die workers must master is the most important in making jewelry, art, the

Model workers should be proficient in mastering these techniques.

Jewelry casting out of tree together, known as the "golden line", this is from the"natural" mold. Gold jewelry blank tree with pliers cut it down. Try to cut on the castingnozzle. Hand strength shear outlet have certain skills

. Casting nozzle with pliers cut fine directly no trouble. And the casting nozzle largerneed right hand grip pliers, the clamp handle close to the table, to the top of theclamp down pressure, shear strength, so the casting. When the left hand to hold the"shear gold tree ’, close to the index finger and

Middle finger cut off by casting, casting and anti shear. From the "golden tree" cutjewelry blank can then they die, they die operation main steps are as follows:

First, water cut in any case castings, always leave the residual water in the jewelryblank, which requires a hacksaw in they die at the beginning of the nozzle completelycut off. Of course not sag sawing. Otherwise it will damage the edge jewelry blank,affecting the quality of the die jewelry.

Second, jewelry casting through washing, cleaning and cutting fried drum saw, forcedoperation, will inevitably cause some deformation damage, especially the rings that circle, with mouth is round, but also from the sides of the finger ring is with the mainstone export in line, and the ring arm and little Shi Xiang

Export coordination. Deformation refers to the circle can be set into the ring with a hammer to tap in the iron, the round. The overall lack of coordination to the ring flaton the anvil with a hammer to correction. Sometimes some jewelry, such asdecoration, line with pliers, tweezers, needle and other jewelry

With the adjustment. They die correction brooch, earring and necklace jewelry have in common with correction ring, also has the difference, the purpose is to make jewelryrestored to its original template modeling.

Third, sometimes need to change the size of the ring finger rings, jewelry, floral mobileconnection lines and with mouth broken jaw and jewelry casting sand hole repair,need welding. Ring ring size sometimes need to be changed, this requires that thering ring off, both shrinkage

Small or expand your mouth will need to re welding. Should be noted that before welding welding must be clean, use the file will end welding export file. So can the ringwelding. Repair broken and broken claw first to remove the residual end of heavycastings, with the right of the line of the claw, the

Welded sturdy.

Jewelry casting they die in the most troublesome is the repair of trachoma, key repairtrachoma is with good welding, such as welding preparation is not good, welding and local jewelry casting the overall color will not be identical, this will affect theappearance of jewelry. Preparation of pads is the prerequisite to ensure the gold content of gold

Adding 2%, 6% zinc. Can also add zinc and cadmium, zinc and cadmium ratio is 2:1,and the total amount of unchanged, zinc is to reduce the melting temperature, repairwelding sheet to melt filling parts trachoma, jewelry blank but does not melt. It is high,low temperature weld
