Custom Necklace Manufacturing: Full OEM & ODM Process Explained

From Concept to Production: Necklace Design Process

Clarifying Design Requirements

• Before customizing a necklace, it is essential to clarify the design objectives, including style (such as minimalist, luxurious, or vintage), material (brass, 925 silver), budget, and target market.
• Different materials affect cost and wearing experience. For example, brass is suitable for large-scale production, cost-effective, and can be plated in various colors; 925 silver is more high-end, ideal for premium or collectible pieces.
• Clarifying these basic parameters provides guidance for subsequent design, material procurement, and production planning.

Concept Sketches and Digital Design Tools

• Initial concepts can be presented through hand-drawn sketches, but modern design relies more on digital tools such as Rhino, MatrixGold, and ZBrush.
• These software solutions transform 2D designs into 3D models, enabling detailed engraving, texture effects, and structural analysis.
• Digital rendering also visually demonstrates metal finish, plating colors, and gemstone settings, giving clients a realistic preview of the final necklace.

Structural Design and Manufacturability Assessment

• Design must not only be aesthetic but also manufacturable. Designers need to consider chain thickness, clasp strength, gemstone setting space, and overall balance.
• Unreasonable designs can increase casting difficulty or cause finished products to be fragile. Early assessment allows structural optimization at the design stage, reducing rework later.

3D Modeling and Rendering

• After conceptual design, 3D modeling creates precise models to ensure dimensions, proportions, and weight meet requirements.
• Rendering can simulate different materials, plating options, and lighting effects, helping clients confirm the final appearance before production and minimizing revisions.

Design Confirmation and Specification Documentation

• Before formal production, the design team produces detailed specifications, including dimensions, weight, plating thickness, gemstone types, and setting methods.
• These documents serve as technical references for production and are critical for communication with a custom necklace manufacturer / Custom necklace factory.
• Professional manufacturers also provide design optimization advice to ensure the design is both beautiful and manufacturable, improving production efficiency.

Complete Necklace Manufacturing Process

• Wax Model Production: The first step in customizing a necklace is creating a wax model for metal casting. Fulcol produces wax models by hand or via 3D printing according to client designs, ensuring complex textures and fine details are accurately reproduced. Wax model precision directly affects the final product detail and is the foundation of high-quality custom necklaces.
• Casting Process: Using lost-wax casting, the wax model is encased in refractory material, melted out, and molten brass or 925 silver is poured in. Fulcol adjusts temperature and timing according to material to ensure smooth metal flow and complete castings. After casting, debris removal and preliminary polishing prepare the piece for fine finishing.
• CNC Precision Machining:For complex pendants and specialized clasps, Fulcol uses CNC machines with precision up to 0.01mm, ensuring tight fit for chain links, clasps, and gemstone areas. This step guarantees structural reliability while preserving design aesthetics.
• Polishing and Surface Treatment: Each custom necklace undergoes multi-stage polishing, including coarse, medium, and fine polishing, for a smooth metal surface. Surface finishes such as high gloss, matte, brushed, or textured are applied according to client requirements, highlighting unique design. Polishing also provides a smooth foundation for plating and gemstone setting, ensuring uniform craftsmanship.
• Gemstone Setting: Based on client customization, prong, bezel, or micro-pave settings are performed, ensuring gemstones are secure and visually optimized. Layout strictly follows design specifications, reflecting creativity and brand style. Experienced setters handle intricate and micro-jewelry designs.
• Plating Process: Fulcol provides high-precision plating to achieve gold, rose gold, white gold, and other custom colors. Plating thickness is adjustable per client requirements, typically 3–5 microns, ensuring wear resistance and long-term durability. Corrosion and abrasion tests are performed to guarantee both beauty and functionality.
• Final Quality Check and PackagingEvery custom necklace undergoes strict inspection for dimensions, weight, plating thickness, and gemstone stability, ensuring alignment with design. Approved pieces are packaged according to client specifications, including gift boxes, labels, and instruction cards, reflecting brand personalization and premium quality.
