Self-developed SH electroplating system, no fading for 3 years

What is electroplating customization ?

Custom electroplating is a surface treatment process for metal jewelry. Electrochemically, a thin layer of metal coating (such as yellow gold, rose gold, or black gold) is added to a brass or stainless steel base to achieve a specific color, luster, and durability. This allows brands to fully control the visual style of their products, from classic luxury to modern fashion, while ensuring corrosion resistance, fade resistance, and wear resistance—perfectly meeting the environmental and aesthetic demands of the European and American markets. As part of our customization services, we integrate ODM/OEM processes, simplifying color standardization and production efficiency, ensuring a seamless transition from concept to mass production for your brand’s designs.

STAR H ARVEST

Full range of electroplating color customization

18k

The 18K high-saturation warm-toned coating precisely matches the Pantone 18-1345 luxury color standard, while the 14K light gold version optimizes the red and copper ratio to achieve a fast, fashionable, lightweight, and neat wearing effect. Both standards have passed the 72H salt spray test.

Rose gold

The palladium-enhanced rose gold plating eliminates the cheap powdery feel, and the exclusive matte etching process combines delicate touch with fingerprint resistance. ΔE < 1.5 after 100 cleanings ensures the long-lasting beauty of wedding products.

Platinum

The 18K palladium-rhodium alloy coating achieves a mirror-grade cool white light (reducing costs by 30%), and the 14K light platinum version presents a Korean blue-white luster. The entire series complies with the EU nickel release standard (<0.2μg/cm²/wk).

Gun black

Medical-grade PVD black plating technology covers the 316L stainless steel base. The 0.5μm dense coating increases scratch resistance by 70%, and the salt spray test is 96 hours without any spots.

bronze

S

The controlled oxidation process simulates the natural aging effect of 3-5 years, and the oil sealing and curing technology locks in the staged patina texture. The mass production yield of American retro-style hang tags is 95%+.

Champagne gold

Zinc-tin particles are added to the 14K base to create a soft, warm tone, suitable for the gradient pearlescent needs of heavy earrings. The anti-discoloration life is extended by 40% after ASTM D4060 testing.

Balancing Durability and Cost through Gold Plating Thickness

Deviations in gold plating thickness will directly erode your profits – choosing 0.1-0.3μm (color retention for 3-6 months) is suitable for fast-moving fashion items, but the return rate in the European and American markets has climbed 37%; 1.5-2.0μm (color retention for 3-5 years) reduces warranty costs by 19% (data from partner brands), and is particularly suitable for long-term sales of classic items; we provide full parameter customization (0.1-5.0μm), combined with your brand positioning (such as DTC emerging brands use 0.5-1.0μm to balance cost-effectiveness, and high-end lines use 2.0μm+PVD process to pass ISTA sweat corrosion testing), free sample delivery to verify the actual color retention period, and avoid the risk of declining gross profit margins due to excessive gold plating or negative reviews caused by insufficient thickness.

Gold plating thickness (micron)
Color retention time (typical estimate)
Other key parameters
Applicable scenario suggestions
Cost impact (relative reference)
0.1-0.3
3-6 months
Extremely thin layer; low corrosion resistance (easily corroded by sweat and chlorine).
Short-term promotional items, disposable accessories, low-cost fashion styles.
Low (economical option, reduces material waste). Suitable for budget-conscious e-commerce startups.
0.5-1.0
1-2 years
Medium thickness; moderately corrosion-resistant (suitable for regular wear).
Everyday accessories and entry-level luxury items (such as mid-range e-commerce series).
Medium (balances performance and cost). Suitable for fast-growing brands optimizing their supply chains.
1.5-2.0
3-5 years
Thicker layer; highly resistant to corrosion (daily wear and tear).
Mainstream product lines and classic models of medium and large brands (such as the core series sold all year round).
Higher (adds a small amount of cost but improves durability). Helps reduce returns and exchanges, and maintain brand loyalty.
2.0+ (eg, PVD or thickened gold)
5+ years
Extremely thick/PVD technology; highest resistance to corrosion (chemical agents and abrasion).
High-end custom-made, waterproof/sports-related accessories (such as smart jewelry or professional accessories).
High (requires process optimization and extended production cycles). Recommended for North American/European brands focused on long-term quality.

FAQ
/01
Is there a minimum order quantity requirement for OEM cooperation?

We offer flexible production solutions. The minimum order quantity for conventional products is 300 pieces. We also support small batch trial orders (minimum order quantity 200 pieces) to verify the process, ensuring zero risk for new customers.

The standard production cycle is 25-35 days. Expedited service is provided during the proofing stage (completed within 7 working days). During the peak period of mass production, an intelligent order scheduling system is used to ensure delivery time.

Implement SH-P multiple quality control system: 1. First piece full size inspection 2. 100% full inspection, equipped with spectrophotometer, hardness tester and other professional equipment to quantify quality control standards.

The entire production process is signed with an NDA confidentiality agreement, and an independent production line is used for closed operation. Once the order is completed, the design files can be delivered to the customer to ensure the security of intellectual property rights.

We provide international test reports in accordance with SGS, LFGB, and other standards to meet REACH and CPSC regulations. We can also provide customized testing for special requirements such as California Proposition 65.
