fine copper wire drawing

In fine copper wire manufacturing, achieving ultra-fine diameters with consistent softness and high surface quality is essential for electronic cables, magnet wires, automotive harnesses, and specialty conductors. The RLB Double-Wire Intermediate Copper Wire Drawing Machine and Continuous Annealing Production Line (RZL280 series) is a high-efficiency solution that draws incoming copper wire from Ø2.6–3.5mm down to a minimum of Ø0.4mm while performing online annealing in a single continuous pass. Available in single-head and double-head configurations, this intermediate drawing line maximizes output, reduces floor space requirements, and delivers bright, uniformly annealed fine wire ready for further processing or bunching.
