Full process customization

우리는 원자재에서 완제품까지 전문적이고 유연한 OEM 맞춤형 서비스를 제공하여 각 제품이 귀사의 시장 위치와 브랜드 톤에 맞도록 보장합니다. 새로운 디자인 및 개발이든 기존 제품 최적화이든 관계없이, 귀하의 요구에 따라 안정적인 품질과 신뢰할 수 있는 납기로 제품을 제작할 수 있습니다. .

Casting customization

We offer flexible options (such as die casting or lost wax) based on your design drawings, supporting both large and small-volume OEM production, addressing customer pain points such as slow prototyping and high tooling costs. Leveraging 20 years of experience to ensure consistency and tolerance control (±0.1mm accuracy), we can shorten first-sample turnaround time to just 5 days. Whether your e-commerce brand requires complex geometries or minimalist, we can match material parameters (for example, optimizing stainless steel hardness), allowing you to focus on brand design rather than production risks.

Customized electroplating

We offer custom colors, thicknesses (ranging from 0.5-3μm), and eco-friendly options (compliant with European and American REACH standards), helping you address the challenges of rapid fading and batch-to-batch color variation. Our ODM partnerships allow for rapid color iteration to match brand positioning (e.g., fast color adjustments for popular e-commerce products). Combined with stainless steel or brass substrates, our customizations extend product lifespan and reduce return rates, while also allowing for small-batch orders to test market response.

Polishing customization

We can adjust the roughness (Ra value 0.2-1.5μm) to suit your product’s style (such as Nordic minimalist style), addressing customers’ pain point of inconsistent surface quality. Twenty years of expertise ensures batch consistency and avoids secondary processing delays. We support ODM needs for brass or stainless steel jewelry, enhancing tactile comfort and adapting to brand owners’ fast-fashion iterations, shortening your time to market.

Logo customization

We can incorporate your brand elements (such as e-commerce logos or cultural icons) to provide in-depth and fast adjustments, addressing issues such as low pattern accuracy or customization delays. Rapid prototyping and an accuracy of <0.05mm support small-batch OEM trial production. This is ideal for personalized upgrades of brass and stainless steel jewelry, enhancing product storytelling and helping brands stand out from the competition without the risk of excess inventory.

Welding customization

We offer material compatibility (such as heat-resistant stainless steel options) and precise positioning control to address customer pain points such as weak welds and poor batch yields. Our 20-year quality control system ensures a 99% pass rate (IP68 waterproof testing). Our ODM service allows you to specify assembly details (such as weld thickness), ensuring the durability of brass products in high-frequency use and reducing after-sales costs. This service is particularly suitable for the mass production needs of medium and large brands.

Inlay customization

We support the matching of sizes and positions of various materials (such as moissanite and rhinestone), addressing issues such as inlay fallout and design limitations. Through modular ODM, we enable rapid prototyping (samples within three days) and accommodate lightweight brass and stainless steel jewelry. This helps e-commerce brands create cost-effective, blockbuster products and increase product premiums without the risk of excessive R&D investment.
