Brass and stainless steel are the first choice for fashion jewelry brands. As a renewable metal, brass is very environmentally friendly. Compared with silver, the cost of brass is only about 20% of that of silver, which is very cost-effective. At the same time, its good ductility can ensure the perfect presentation of most processes. Stainless steel can use vacuum plating technology to achieve a longer electroplating color retention time and good stability. The material itself has extremely high hardness to prevent scratches caused by daily wear. Stainless steel itself is anti-allergic and recyclable, taking into account the dual advantages of safety and environmental protection for daily wear.
SH has been manufacturing brass/stainless steel for over 20 years. We understand the deep demands of jewelry brands for the supply chain – from the technical transformation of accurate design drafts, to the material system that meets environmental standards, to the agile production model that ensures the rhythm of fast fashion. We are equipped with a 26-person designer team to provide 1:1 drawing optimization, and have an exclusive electroplating factory to ensure electroplating standards. All production lines adopt modular production to achieve a flexible delivery period of 7-40 days. We have completed the delivery of 30,000+ hot products per month in the peak season for more than 300 independent jewelry brands. Unlike conventional factories, we assign an independent product manager to each partner to follow up the whole process, and achieve a 97% order 0 customer complaint rate through the three levels of raw material testing-process quality inspection-final inspection.
With 20 years of experience in brass jewelry customization, we have achieved a 47% higher precision of special-shaped structures than conventional casting processes based on a complete ERP system and CNC precision engraving technology with an error of 0.05mm. Through the combination of medical-grade ROHS substrate and 7-layer electroplating protection technology (including vacuum ion membrane), the color retention life of the product is extended by 3 times compared with conventional jewelry.

More than 3,000 mold sets can verify 140 new drafts every day. The self- developed SH-JZ process shortens the prototype development cycle to 72 hours. It supports the first 200 trial production + mold fee refund policy, and is equipped with EU REACH heavy metal migration pre-inspection service.
The fully automatic conversion from 3D files to fully coated samples is completed in an average of 3-7 days. The laser ion engraving technology ensures that the label will not fade after 10,000 frictions. The integrated recycled steel traceability system and cross-border carbon credit accounting module can reduce carbon emissions by 28kg per 10,000 pieces produced.
The five-axis precision engraving machine tool can achieve 0.3mm ultra-thin silver jewelry without deformation processing. The embedded anti-fracture stress structure has passed the bending test. It is equipped with a visual precious metal flow monitoring terminal, supports silver content detection, and 100% guarantees 925 silver content.
