Hasung-Tungsten Carbide Flat Wire Rolling Mill Machine For Jewelry Chain Manufacturing

The HS-FWR1 fflat wire rolling machine is designed to reduce round metal wire into precise flat wire for jewelry and precious metal applications. The machine uses tungsten carbide rollers to apply controlled pressure during the rolling process, helping achieve consistent wire dimensions and a smooth surface. It can process materials such as gold, silver, copper, and various metal alloys, depending on the production requirements. With a rolling thickness range of 3–0.1 mm, the machine is suitable for producing flat wire used in box chains, snake chains, and other jewelry components.

Tungsten carbide rollers are used in the flat wire rolling mill because they combine high hardness with strong wear resistance. During continuous rolling, the rollers are exposed to repeated pressure and friction, so roller durability directly affects dimensional consistency and production stability. Their hard working surface helps maintain the roller profile over extended operation, supporting more consistent flat wire thickness and width. Tungsten carbide also provides a smooth rolling surface that is suitable for processing precious metals such as gold and silver, where surface quality is important. For jewelry chain manufacturers, this helps reduce roller wear and maintain reliable results during repeated wire-flattening operations.

Step 1: Round Wire Feeding

Round metal wire is fed into the rolling mill and positioned for stable processing.

Step 2: Rolling & Flattening

Tungsten carbide rollers apply controlled pressure to gradually reduce the round wire and form a flat profile.

Step 3: Thickness Adjustment

The roller gap and operating speed are adjusted to achieve the required flat wire thickness and dimensions.

Step 4: Flat Wire Output for Chain Making

The finished flat wire exits the mill and is ready for subsequent jewelry chain forming and manufacturing processes.

✔Box Chain Manufacturing — Produces consistent flat wire for forming the square links used in box chain production.

✔Snake Chain Manufacturing — Provides flat wire with controlled dimensions for subsequent forming and shaping processes.

✔Gold Jewelry Chains — Suitable for flattening gold wire into precise profiles for different chain designs.

✔Silver Jewelry Chains — Supports consistent silver wire processing for chain production and other jewelry components.

✔Copper & Alloy Wire Processing — Can process copper and selected metal alloys for cost-effective jewelry and decorative chain applications.

✔Custom Flat Wire Production— Allows manufacturers to prepare flat wire in different thicknesses according to specific chain designs and production requirements.
