Production Process
STAINLESS STEEL WIRE
Cold drawing
Annealing
Spool winding
Metal wire is drawn through a series of progressively smaller dies, using metal plasticity to gradually reduce its diameter.
Heat treatment conditions must be properly adjusted according to product requirements, with the main purpose of restoring the material structure after cold working hardening.
Winding tension directly affects the product's surface quality, and the tightness of the finished spool. Therefore, tension settings must be properly adjusted according to the wire diameter.
Inspection
Quality inspections are conducted at every stage, from raw materials to finished goods, to ensure consistent quality and meet customer requirements.
Packing
Each spool is weighed, labeled, packed, and undergoes a final inspection before shipment.

WIRE DRAWING DIE
Bonding
We use powder metallurgy to sinter the diamond directly into the tungsten carbide body, ensuring a secure bond that prevents loosening during wire drawing and extends die life and stability.
Laser Piercing
New automatic laser drilling equipment from Germany features 0.1-micron high resolution and precise angle measurement, enabling faster and more accurate diamond drilling.
Shaping
Polishing is critical in die manufacturing, as it directly affects wire drawing life and stability. Poor polishing increases resistance, results in rough surfaces, dull finish, unstable wire size, and accelerates die wear.
Finishing
Die angle and bearing length directly affect drawing resistance. Inconsistent angles or lengths can significantly reduce efficiency on drawing machines.
Inspection
Microscopes are used to inspect drawing dies, allowing inspectors to assess and decide if recutting, repolishing, or resizing is required.
