Such as the comprehensive production process of copper earringsRobin Wong
Pressed film. A mold is formed by pressing with the inner glue and the outer glue. Then using the bistoury cutting, digging, stirring up and pressing to make a mold that can be waxed. The production staff’s elegant and skillful professional movements show all the craft skills.
Injection wax. Using semi-automatic waxing machine to press the high quality wax material into the mold. Wax mold, the rudiment of each product comes out.
Wax setting. Inserting the micro zircons into the wax mold one by one. Undoubtedly, it is a detailed work. Look at the micro zircon, which is sucked up by the air pipe and inserted into each stone position. If you use too much force, it will damage the wax table. If you use too little force, it will not be inserted properly. Just by this way to demonstrate the craftsmanship of the producer.
Tree planting.The wax models are attached to the core of the wax tree, just as the seedlings were grafted onto a big tree. Gaps, inclination and so on are all testing the work experience of the production staff.
Molding. Molding is an important process of transferring wax mould into copper workblank, also the representative process of copper casting jewelry. The wax trees are irrigated by high-heat copper liquid to form initial copper workblank. It seems like a magic.
Cutting. Cutting the copper tress which are molded. Cutting the copper workblanks down one by one.
Polishing. Polishing the finished copper jewelry workblank with grinding wheel and abrasive paper to make the design beautiful and the surface smooth, then manual repair and gradual formation are carried out.
Manual paving. Placing the polished copper workblanks on the copper platform,inserting zircons and tightly clamping the copper claws with a tong. It is a testing for workers skill to finish this important step with such a small tong.
Burn-in. Burn-in, also known as welding, is often used for the stitching of accessories that can’t be turned out of a model, common in earring and needle splicing.For this process, we also need to make a mold, which seems to use more time, but actually it is sharpening the knives without delaying the job of cutting wood. While welding, we pay attention to control the size and firm degree of soldering point to make the design beautiful and sutructure stable.
