Silver Wire, Gold Wire Solution

In the silver and gold wire industries, wire drawing dies are essential for achieving ultra-fine, high-precision wires with minimal material loss, ensuring top performance in jewelry, electronics, and precision manufacturing.

Silver Wire, Gold Wire (precious metal)

Silver and gold wires often require extremely tight tolerances (±0.005 mm or better) for use in microelectronics, bonding wires, fine jewelry, and medical devices.
A flawless surface is essential to prevent defects in bonding (electronics) or visible imperfections in jewelry.
Precious metals are extremely valuable; drawing dies must ensure smooth, efficient reduction without excessive friction or surface damage that could cause wastage.
High-quality drawn wires must be free from micro-cracks or internal stresses to facilitate subsequent plating, coating, or bonding processes.
