In the luxury jewelry market, a high-quality chain isn’t just a “support” for pendants or bracelets—it’s a statement of craftsmanship. Consumers judge premium jewelry by the chain’s flexibility, durability, link consistency, and finish. However, traditional chain production faces pain points like uneven links, fragile welds, limited style options, and high labor costs.
SuperbMelt automatic gold chain making machines solve these challenges by integrating precision machining, automation, and advanced welding technology. This comprehensive guide will walk you through every step of high-end chain production—from raw material preparation to post-processing and custom design—while highlighting how SuperbMelt’s equipment elevates efficiency, quality, and versatility for jewelry manufacturers, studios, and custom workshops.

High-end chains (used in luxury necklaces, bracelets, and pendant chains) stand out for their structural integrity, aesthetic consistency, and functional flexibility. SuperbMelt machines are engineered to produce chains that meet these strict standards

1.1, Versatile Chain Structure & Style Options

SuperbMelt machines support a wide range of chain configurations to cater to diverse market demands:

• Strand combinations: Single-strand (delicate pendant chains), double-strand (elegant bracelets), triple-strand (statement necklaces), and multi-strand (custom layered designs) chains—all achievable with quick mechanical adjustments, no need for separate equipment.
• Link movement & flexibility: Chain links are designed to rotate and twist freely, ensuring the chain drapes smoothly on the body (critical for comfort) while maintaining structural strength. Unlike cheap chains that feel stiff or break easily, SuperbMelt-produced chains balance flexibility with durability—tested to withstand 50,000+ bending cycles without link deformation or breakage.
• Classic & custom styles: Specializes in high-demand styles like Curb chains (flattened, interlocking links), Cable chains (simple oval links), and custom combinations (e.g., dual-execution spirals, long-short link mixes). The machine’s programmable link torsion allows for innovative designs, making it easy to launch new styles or replicate vintage chain patterns.

1.2, Application Scope for Luxury Jewelry

The chains produced by SuperbMelt machines are ideal for:

• Necklaces: Delicate 0.2–0.5mm wire chains (for dainty pendants) to bold 1.0–1.2mm multi-strand chains (for statement pieces).
• Bracelets: Flexible single/double-strand chains (everyday wear) and sturdy triple-strand chains (designer collections).
• Pendant chains: Precision-calibrated link spacing ensures pendants sit evenly without sliding or tangling.
• High-end custom jewelry: Supports small-batch production of limited-edition chains (e.g., brand signature styles) and one-of-a-kind custom designs (e.g., personalized link patterns).

The quality of a chain starts with raw materials—SuperbMelt machines are optimized for precious metals and require specific material preparation to ensure consistent forming and durability.

2.1, Supported Metal Materials & Selection Criteria

SuperbMelt machines are compatible with all premium metals used in luxury jewelry:

• Precious metals: Gold (14K, 18K, 24K), white gold (rhodium-plated or alloyed), platinum, and 925 sterling silver. These materials require precise processing to avoid waste and maintain purity.
• Hard alloys: Tungsten carbide, titanium alloy, and stainless steel (for fashion luxury chains). These harder materials demand machines with robust torque and precision—SuperbMelt’s industrial-grade motors handle them seamlessly.

Material selection tips:

• Soft metals (24K gold, pure silver): Choose wires with slightly higher tensile strength (≥300 MPa) to prevent stretching during twisting.
• Hard metals (platinum, tungsten carbide): Opt for annealed wires to reduce brittleness and ensure smooth bending.
• Mixed-material chains (e.g., gold-plated silver): Ensure the base metal (silver) has consistent thickness to avoid plating unevenness after chain formation.

2.2, Gold Wire Specifications & Requirements

Wire diameter directly impacts chain style and functionality—SuperbMelt machines support a wide range to cover most high-end applications:

• Wire diameter range: 0.2–1.2mm (the sweet spot for luxury chains).
  • 2–0.5mm: Ideal for delicate pendant chains and thin bracelets (lightweight, comfortable for daily wear).
  • 6–0.9mm: Perfect for medium-weight necklaces and bracelets (balances durability and elegance).
  • 0–1.2mm: Used for bold statement chains and multi-strand designs (sturdy, visually striking).
• Wire quality standards:
  • Uniform diameter (tolerance ±0.01mm): Ensures consistent link size—no “thick” or “thin” sections that ruin the chain’s appearance.
  • Smooth surface: Free of scratches, oxidation, or impurities (prevents defects during twisting and welding).
  • Consistent hardness: Avoids uneven stretching or breaking during production—SuperbMelt recommends wires with Rockwell hardness (HRB) of 60–80 for optimal results.

2.3, Critical Preprocessing Steps (Non-Negotiable for Quality)

Raw metal wire requires four key preprocessing steps to ensure stable chain formation—SuperbMelt machines work seamlessly with preprocessed wires, and skipping these steps leads to defects (e.g., deformed links, weak welds):

Step 1: Annealing (Softening the Metal)

• Purpose: Reduces internal stress in the wire (caused by manufacturing) to improve flexibility and prevent cracking during twisting.
• Process: Heat the wire to 600–800°C (varies by metal: gold 700°C, silver 650°C, platinum 800°C) in a controlled atmosphere (to avoid oxidation) and cool slowly.
• SuperbMelt compatibility: The machine’s feeding system handles annealed wires gently, avoiding reintroducing stress.

Step 2: Cleaning (Removing Impurities)

• Purpose: Eliminates oil, dust, and oxidation from the wire surface—contaminants cause poor welding adhesion and surface defects.
• Process: Ultrasonic cleaning (15–20 minutes) with a mild detergent (pH 7–8) followed by rinsing and drying. For precious metals, use a non-abrasive cleaner to avoid scratching.
• Why it matters: Clean wires ensure laser/microspot welding penetrates evenly, creating strong, seamless welds.

Step 3: Drawing (Refining Diameter & Surface)

• Purpose: Reduces the wire to the exact target diameter (0.2–1.2mm) and creates a smooth, uniform surface.
• Process: Pull the wire through diamond dies (gradually reducing diameter) to ensure consistency. For hard metals, use multiple drawing passes with intermediate annealing.
• SuperbMelt advantage: The machine’s tension control system adapts to drawn wires of different diameters, preventing stretching or breakage during feeding.

Step 4: Precision Cutting (Preparing for Spiral Formation)

• Purpose: Cuts the drawn wire into spools of uniform length (typically 50–100kg per spool) for easy loading into the machine.
• Process: Use a precision cutter with a tolerance of ±0.5mm to avoid uneven spooling.
• Efficiency tip: SuperbMelt machines accept standard 50–100kg spools, reducing downtime from frequent spool changes.

Link formation is the core of chain production—SuperbMelt’s automated system eliminates manual errors, ensuring every link is identical (a must for high-end jewelry).

3.1, Automated Spiral Formation & Link Cutting

The machine’s core workflow for link creation is fully automated, with zero manual intervention:

• Spiral formation: The preprocessed wire is fed into a precision spiral-forming module, which twists the wire into a continuous spiral (the shape of the spiral determines link style: e.g., round for Cable chains, flattened for Curb chains). The spiral’s pitch (distance between turns) is programmable via the machine’s PLC, ensuring consistent link size (tolerance ±0.02mm).
• Automatic cutting: A high-speed precision cutter slices the spiral into individual links—each link is identical in size and shape. For example, a Cable chain with 3mm links will have every link measure exactly 3mm, with no variation (unlike manual cutting, which often has ±0.1mm errors).
• Waste reduction: The automated process minimizes scrap—SuperbMelt machines achieve a 99.5% material utilization rate during link formation, critical for expensive precious metals.

3.2, Quick Style & Direction Switching (Maximize Versatility)

One of SuperbMelt’s key advantages is its ability to switch between chain styles and directions in minutes, eliminating the need for multiple machines:

• Style switching (Curb ↔ Cable): A simple quick-change mechanism allows you to switch from Curb chains (flattened links) to Cable chains (round links) in ≤15 minutes—no tools required. This is ideal for manufacturers producing multiple styles for different clients or collections.
• Direction switching (left ↔ right twist): The machine’s programmable torsion system lets you switch between left-twisted and right-twisted links, enabling the production of two chains with identical pitch (perfect for coupling into double-strand designs or matching necklace/bracelet sets).
• Multi-style compatibility: Beyond Curb and Cable chains, the machine supports custom link shapes (e.g., square, oval, rectangular) via interchangeable forming dies—simply swap the die and adjust the PLC settings to launch a new style.

3.3, Full Automation: From Feeding to Density Control

SuperbMelt machines are fully automated, covering every step from wire feeding to link assembly:

• Automatic wire feeding: A motor-driven feeder with adjustable tension (0.1–1.0N) feeds the wire into the forming module at a consistent speed (synchronized with spiral formation to avoid stretching).
• Link assembly: The cut links are automatically aligned and interlocked—no manual sorting or assembly. The machine’s vision system checks for misaligned links and rejects them (reducing defects to ≤0.3%).
• Density control: A built-in chain density sensor adjusts the link assembly speed to ensure uniform link spacing. For example, a necklace chain with 5 links per centimeter will have consistent spacing across its entire length (no “crowded” or “spaced-out” sections).
• Torsion angle adjustment: The PLC allows precise control of link torsion (0–360°), enabling custom designs like twisted Curb chains or spiral-link chains. Torsion settings are saved as recipes, so you can recall them instantly for repeat orders.

3.4, Key Advantages of Automation for High-End Production

• Consistency: Every link is identical in size, shape, and spacing—critical for luxury jewelry, where even minor variations are noticeable to consumers.
• Efficiency: The machine processes 80–120 meters of chain per hour (depending on link size), 5–10x faster than manual production. For example, a 50-meter batch of 0.5mm Cable chain takes just 30–45 minutes to produce.
• Labor savings: A single operator can manage 2–3 SuperbMelt machines, reducing labor costs by 70% compared to manual production (which requires 1 operator per machine).
• Scalability: The automated system handles both small-batch custom orders (e.g., 10 meters of a unique chain) and large-scale mass production (e.g., 1,000 meters for a retail collection) with the same consistency.

Welding is the most critical step for chain durability—poor welds lead to broken chains (a nightmare for luxury brands, as they damage reputation and lead to returns). SuperbMelt uses advanced welding technology to create strong, seamless welds.

4.1, Welding Technologies: Microspot vs. Laser Welding

SuperbMelt machines offer two welding options, tailored to different metals and chain styles:

• Microspot welding: Ideal for soft metals (24K gold, pure silver) and thin wires (0.2–0.5mm). Uses a small electrical current to create a precise weld spot, avoiding heat damage to the delicate links.
• Laser welding (updated models): Perfect for hard metals (platinum, tungsten carbide), thick wires (0.6–1.2mm), and high-volume production. A fiber laser delivers concentrated heat to the link interface, creating a seamless, strong weld. The laser welding torch automatically locates the link interface (via vision system), ensuring accurate positioning even for tiny links.

4.2, Weld Quality: Strength & Aesthetics

SuperbMelt’s welding process sets high-end chains apart from cheap alternatives:

• Weld strength: The weld joint’s tensile strength reaches 95% of the base metal—meaning the chain is just as strong at the weld as it is at the link itself. For example, a 18K gold chain with laser-welded links can withstand 150–200N of tension (enough to support heavy pendants or resist pulling).
• Seamless appearance: The weld spot is nearly invisible (≤0.1mm in diameter), so the chain looks smooth and uniform—no unsightly bumps or discoloration (common with manual welding).
• Flexibility retention: Unlike over-welding (which makes links brittle), SuperbMelt’s controlled welding process preserves the link’s flexibility. Welded links can still rotate and twist freely, ensuring the chain drapes naturally.

4.3, Automated Welding Quality Control

To ensure every weld is perfect, the machine includes built-in quality control:

• Vision inspection: A camera checks each weld spot for size, position, and integrity—rejecting any links with incomplete welds or misaligned joints.
• Tension testing (optional add-on): For high-volume production, an integrated tension tester pulls every 100th link to verify strength, providing real-time data to the operator.
• Error alerts: If the machine detects a welding issue (e.g., laser power fluctuation), it stops automatically and sends an alert—preventing a batch of defective chains.

After welding, the chain undergoes post-processing to refine its appearance and performance—this step is what makes a “good” chain into a “luxury” chain.

5.1, Annealing & Shaping: Perfect the Chain’s Form

• Post-weld annealing: The chain is heated to 400–500°C (lower than preprocessing annealing) to relieve stress from welding and link formation. This step ensures the chain retains its shape and flexibility, even after repeated wear.
• Precision shaping: The chain is fed through a series of shaping rollers that straighten it (ensuring no kinks) and adjust link alignment. For Curb chains, the rollers flatten links to the exact desired thickness (e.g., 0.8mm for a medium-weight chain).

5.2, Cleaning: Remove Contaminants from Welding & Shaping

• Ultrasonic cleaning: The chain is placed in an ultrasonic cleaning bath (with a pH-neutral cleaning solution) to remove welding residue, oil, and metal dust. This step is critical for surface finishing—contaminants cause uneven polishing or plating.
• Rinsing & drying: The chain is rinsed with deionized water to remove cleaning solution, then dried in a heated air chamber (to avoid water spots). For precious metals, a nitrogen gas dry is available as an option to prevent oxidation.

5.3, Surface Finishing: Polishing & Plating

SuperbMelt machines work seamlessly with post-processing equipment to achieve luxury finishes:

• Precision polishing: The chain is fed into a barrel polisher or belt polisher (depending on desired finish) with abrasive media (e.g., ceramic beads for gold, steel shot for silver). Polishing removes minor surface imperfections and creates a smooth, reflective finish. For matte finishes, a specialized abrasive media is used.
• Plating (optional): For white gold or gold-plated chains, the polished chain undergoes electroplating (e.g., rhodium plating for white gold) to achieve a uniform, durable finish. The machine’s consistent link size ensures even plating thickness (no “thin” spots that wear off quickly).
• Custom finishes: The machine supports specialty finishes like brushed (using a wire brush attachment), hammered (via post-processing dies), or antiqued (via oxidation and polishing)—all of which can be integrated into the production line.

5.4, Final Quality Inspection: Meet High-End Standards

Every chain undergoes a rigorous inspection before leaving the factory—SuperbMelt’s quality control process ensures only perfect chains reach customers:

• Link spacing check: A laser measuring tool verifies link spacing is consistent (tolerance ±0.03mm) across the entire chain.
• Straightness test: The chain is laid on a precision flat surface to check for kinks or bending (rejected if deviation exceeds 0.1mm per meter).
• Weld quality inspection: A magnifying camera (100x zoom) checks every weld spot for integrity—no cracks, gaps, or discoloration.
• Tension testing: Random samples are pulled to verify weld strength (must withstand ≥120N for 14K gold chains).
• Aesthetic inspection: The chain is inspected for scratches, oxidation, or uneven finishing—only chains with flawless surfaces pass.

SuperbMelt machines are designed to handle both custom orders and mass production—critical for modern jewelry businesses that need to adapt to market demands.

6.1 Advanced Customization via PLC & Electronic Speed Control

The machine’s PLC (Programmable Logic Controller) and electronic speed regulator give you full control over chain design:

• Torsion adjustment: Program link torsion (0–360°) to create custom twisted chains (e.g., a 45° twist for a unique Curb chain) or multi-twist designs (e.g., alternating 30° and 60° twists).
• Length control: Set the chain’s final length (e.g., 45cm necklaces, 18cm bracelets) with precision (±0.1cm)—the machine automatically cuts the chain to the exact length after assembly.
• Density adjustment: Adjust link density (number of links per centimeter) to create lightweight or heavyweight chains. For example, a delicate pendant chain might have 6 links per cm (lightweight), while a statement chain has 4 links per cm (heavier, more substantial).
• Recipe storage: Save custom settings (torsion, length, density, link size) as recipes—recall them instantly for repeat orders or batch production of custom designs. The machine can store up to 50 recipes, ideal for studios with multiple clients.

6.2 Quick Material & Style Switching (Minimize Downtime)

SuperbMelt machines are built for versatility, allowing you to switch between materials and styles with minimal downtime:

• Material switching: The machine’s feeding system and welding parameters are adjustable for different metals—switch from 18K gold to 925 silver in ≤30 minutes (just adjust tension, welding power, and post-processing settings).
• Style switching: As mentioned earlier, style and direction switches take ≤15 minutes—no need to reconfigure the entire machine. This is perfect for small-batch production (e.g., 50 meters of gold Cable chain, then 30 meters of silver Curb chain).
• Custom link dies: Interchangeable forming dies let you create unique link shapes (e.g., heart-shaped, star-shaped, brand-logo-shaped) for custom orders. SuperbMelt offers custom die design services—send your link design, and they’ll create a die tailored to your needs.

6.3 High Efficiency for Mass Production & Custom Orders

Whether you’re producing 1,000 meters of a best-selling chain or 10 meters of a custom design, the machine delivers efficiency and consistency:

• Mass production capabilities: The machine runs 24/7 (with automatic lubrication and heat dissipation) for high-volume orders. It processes 80–120 meters per hour, so a 1,000-meter batch takes just 8–12 hours (vs. 40–50 hours with manual production).
• Custom order efficiency: Small-batch custom orders (1–50 meters) are processed just as quickly—no setup fees or long lead times. The machine’s recipe storage means you can recall custom settings in seconds, avoiding repeated adjustments.
• Cost savings: The combination of high material utilization (99.5%), labor savings (70%), and low defect rates (≤0.3%) makes the machine extremely cost-effective. For a medium-sized manufacturer, the ROI is typically achieved within 6–12 months.
• Lightweight & hollow chain production: The machine excels at producing thin, hollow, and lightweight chains—ideal for luxury jewelry (where “lightweight comfort” is a key selling point). Hollow chains made with SuperbMelt machines are 30–40% lighter than solid chains of the same size, while maintaining durability (thanks to strong welds and precision forming).
