With nearly 20 years of profound experience, we focus on the customized production (OEM/ODM) of brass and stainless steel jewelry. We are familiar with the strict quality and regulatory standards of global brands (such as RoHS/REACH), and can respond quickly and provide full-link solutions from material selection, collaborative design to small-batch agile production. Relying on mature technology and strict quality inspection system, we ensure product consistency and on-time delivery, helping medium and large brands and growing e-commerce companies to expand the market with better cost and higher efficiency.
We have mature brass and stainless steel jewelry production lines with an annual production capacity of more than 4 million pieces. We are equipped with multiple precision equipment to achieve one-stop production from mold development to finished product processing.
Whether it is delicate hollow carving, multi-layer electroplating, or difficult special-shaped welding, we can accurately meet your creative needs.
Support small batch quick proofing, large batch production, and can adjust production schedule according to sales rhythm. Flexible order management mode and provide you with real-time feedback on production progress.
Average order delivery cycle is 15-25 days. Urgent needs can be communicated for expedited production. Relying on a complete logistics system and long-term cooperative freight channels, we ensure on-time delivery to the global market.
We continue to invest in the research and development of new alloys and environmentally friendly materials, such as nickel-free stainless steel (in compliance with EU nickel release standard EN 1811) and hypoallergenic brass alloy (suitable for sensitive skin). The laboratory is equipped with a spectrometer and salt spray test equipment to ensure the corrosion resistance (neutral salt spray test ≥ 72 hours without oxidation), ductility (elongation at break ≥ 20%) and cost controllability of the materials.
By optimizing electroplating formulas (such as cyanide-free gold plating) and vacuum plating (PVD) processes, we achieve precise control of coating thickness (±0.1μm), color stability (ΔE≤1.5) and wear resistance (5,000 steel wool tests without bottom exposure). The “double coating technology” (bottom layer wear resistance + surface layer color development) developed for the North American market can extend the life of gold-plated products by more than 3 times.
CNC precision engraving (accuracy ±0.05mm) and laser welding (weld strength ≥90% of base material) technologies are used to solve the burr and deformation problems of traditional jewelry production. The independently designed “multi-station linkage production line” realizes seamless switching between small batches ( starting from 200 pieces) and large batches (average 3,000 pieces per day), shortening the product delivery cycle by 30%.
We have established 12 quality inspection nodes from raw material storage (XRF spectrum detection) to finished product shipment (full inspection + AQL sampling). We have introduced AI visual inspection system (defect recognition rate ≥ 99.7%) and mechanical tester (hook durability test ≥ 2,000 times) to ensure that each product meets customer technical drawings (GD&T tolerance standards) and European and American market regulations.
From material selection, casting, assembly to electroplating, polishing and packaging, we have set up strict quality inspection checkpoints at more than 60 key nodes, covering material composition and environmental testing (such as nickel release, lead content), physical performance testing (salt spray anti-discoloration, torque, drop, snap-fit function) and process inspection (electroplating layer thickness adhesion, polishing uniformity, welding strength) to ensure that each batch of products meets your design specifications and safety standards, and achieves stable quality delivery.
Each product has been subjected to 1000+ friction tests to ensure that the coating, electroplating and surface treatment are durable and wear-resistant. Real simulation of long-term wear and tear, strict quality control
High-precision automatic wax injection, with an error control of ±0.05mm, ensures smooth jewelry lines and precise details, reduces manual mold repair costs , and shortens sample development cycle by more than 20%.
The process from design to sample can be completed within 48 hours , supporting complex hollowing, three-dimensional carving and other fine structures, accelerating design iterations, and helping brands seize market opportunities.
The 72-hour anti-corrosion test strictly verifies the ability of stainless steel and brass alloys to resist sweat and seawater corrosion, ensuring that the product will not oxidize when worn for a long time in the high humidity environment of Europe and the United States.
