Your Copper Wire Drawing Plant – Project Flow & Process Description

Project Overview

This project is designed to manufacture fine copper wire from 8 mm copper rod coils.

Process Flow

Step 1: Raw Material

Copper Rod Coil

The primary raw material is 8.0 mm Electrolytic Tough Pitch (ETP) Copper Rod Coil or CCR, typically purchased from copper rod manufacturers.

Input Material:

• Copper Rod Diameter: 8.0 mm
• Material: ETP Copper Rod, CCR
• Coil Weight: As per supplier standard

Step 2: Rod Breakdown Machine (RBD)

Purpose

The Rod Breakdown Machine reduces the diameter of the copper rod from 8.0 mm to approximately 1.6 mm through multiple drawing dies.

Process

• Input: 8.0 mm Copper Rod
• Output: 1.6 mm Copper Wire
• Continuous drawing through multiple die stages
• High production efficiency
• Suitable for feeding Fine Wire Drawing Machines

Output

• Copper Wire Diameter: 1.6 mm

Step 3: Fine Wire Drawing Machine

Purpose

The Fine Wire Drawing Machine further reduces the wire size to fine diameters required for electrical applications.

Process

• Input: 1.6 mm Copper Wire
• Output Range: 0.15 mm – 0.40 mm
• Multi-wire or single-wire drawing configuration
• High-speed operation
• Precise diameter control

Output

Fine Copper Wire:

• 0.15 mm
• 0.20 mm
• 0.25 mm
• 0.30 mm
• 0.40 mm

(Depending upon customer requirements)

Step 4: 32 Heads Offline Tube Annealing Machine

Purpose

After drawing, copper wire becomes hard and loses flexibility. Annealing restores softness, ductility, and conductivity.

Process

• Input: Drawn Copper Wire (0.15–0.40 mm)
• Annealing through tube-type heating chambers
• Controlled temperature cycle
• Cooling after annealing

Machine Configuration

• 32 Annealing Heads
• Offline Operation
• Suitable for multiple spool processing simultaneously

Output

• Soft Annealed Copper Wire
• Improved Conductivity
• Better Flexibility
• Suitable for further processing

Final Product

Annealed Copper Wire

Diameter Range:

• 0.15 mm – 0.40 mm

The annealed wire can now be utilized in two different manufacturing routes.
