Product Positioning

This high-precision, high-efficiency, non-contact permanent marking solution is suitable for a variety of applications, including industrial manufacturing, precision machining, and customization.

Using 355nm short-wavelength ultraviolet laser, it is specially designed for ultra-fine cold processing and solves the problem of permanent marking of heat-sensitive materials, highly reflective metals and polymer materials.

 

Repair welding: Demonstrate broken chain repair, earring repair welding, claw setting reinforcement, etc.

Non-destructive repair is the biggest advantage of laser welding over traditional flame welding, directly creating economic benefits and reputation for clients.

Broken Chain Repair:
Necklaces and bracelets that break unexpectedly, often with complex links (such as melon seed chains, box chains, and ripple chains), are difficult to repair with traditional methods and are prone to leaving marks.
The laser can precisely focus on the tiny break in a single link, achieving a perfect connection without damaging surrounding links or welds. The repaired joint is highly strong, and the weld is virtually invisible, achieving a "spotless repair."

Ear Stud Repair:
Scenario: The base of an earring stud breaks due to long-term wear or ripping, a common repair procedure.
Precisely locating the connection between the stud and the earring plate eliminates the need for overall heating, preventing heat-sensitive gemstones (such as emerald and tanzanite) from chipping or devitrification due to high temperatures. The weld is secure and perfectly shaped.

Prong Setting Reinforcement and Repair:
Ring prongs can become thinner, deformed, or even broken due to long-term wear, posing a risk of the main stone falling out. Traditional methods require removing and resetting the gemstone, which is risky and time-consuming.
Solution: Without removing the gemstone, fine prongs can be directly reinforced with filler or welded. The laser's minimal heat-affected zone avoids damaging the gemstone, significantly improving repair safety and efficiency.

Bracelet Band Resize: After shortening or lengthening, seamless butt welding is performed. After the weld is finished, the joint can be machined and polished in the same way as the original.
Ring Band Resize: After cutting the shank and adding material, the joint is welded.
Antique Jewelry Restoration: Minimal intervention is performed on fragile and valuable antique pieces, preserving their original historical appearance.

 

Custom made:Complex hollow parts splicing, dissimilar metal welding (such as gold inlaid jade base), etc.

Realizing possibilities allows designers and metalworkers to break through the limitations of traditional crafts and create works that were previously difficult to achieve.

 

Complex Hollow Piece Assembly:
Scenario: Creating pendants or rings with intricate hollow patterns, such as those in Chinese or Gothic styles, requires precise three-dimensional assembly of multiple finely cut components.
Solution: Using a high-definition vision system for magnification, solder points can be precisely placed at extremely small joints, enabling welding from the inside out. No solder points are visible from the front, maintaining an absolutely clean and smooth surface.
Dissimilar Metal Welding:
Scenario:Gold-in-Jade/Gold-in-Porcelain: Creating precious metal (such as gold) bezels for jade and porcelain requires a secure and aesthetically pleasing bond between metal and non-metallic materials.
Two-Tone/Multi-Tone Gold Pieces: Joining different colors of gold (such as 18K yellow gold, 18K white gold, or rose gold), or gold and platinum, creates stylish designs with striking color contrast.
Solution: By precisely controlling energy output and duration, optimal welding parameters can be found for the melting points of the two materials, achieving a strong molecular-level bond and avoiding weld failure, deformation, or color contamination caused by different melting points.

Micro-inlay production: Welding tiny inlays and bases for clusters of small diamonds.
Mechanical jewelry production: Welding precision components such as "Lu Ban locks" and movable joints.
Gold/silver inlay: Pressing gold or silver wire into grooves in steel or titanium, laser welding is used to secure the pieces in place, providing greater control than traditional heat welding.

 

Accessory welding: Precision welding of buckles, pendant rings and other small parts

 

Ultimate precision and efficiency liberate craftsmen from tedious and eye-straining work.

Weld spring clasps, lobster clasps, magnetic clasps, and other accessories to necklaces and bracelets. These clasps are typically small and contain internal spring mechanisms, making them very sensitive to heat.

Solution: Lasers precisely strike the connection point between the clasp and the bracelet, preventing heat transfer to the inner clasp and damaging the spring. This results in fast welding speeds, a high yield rate, and virtually no scrap.

Welding Pendant Rings/Jump Rings:
Welding bail rings or jump rings for pendants. The rings must close perfectly, smoothly, and without snagging.

Solution: Welding seamlessly to the rings, requiring minimal or no post-weld polishing. The rings are smooth and round, and their strength far exceeds that of mechanically closed rings.

Ear Hook/Stud Welding: Quickly weld various ear hooks to the main earrings.

Brooch Tube Welding: Precisely weld the pin tube to the back of the brooch, ensuring a vertical, secure connection without penetrating the front.

Nameplate Welding: Welding small nameplates engraved with brand logos or signatures to custom pieces.

1-Wavelength Advantage: The wavelength of a YAG laser is 1.064 μm . This wavelength has a very high absorption rate for precious metals such as gold, silver, and platinum, as well as materials such as copper and titanium. This means that the laser energy is more efficiently absorbed by the material and converted into heat, achieving rapid melting and welding.
