Details of Production Line
- Process of Flat Magnet Wire Manufacturing
1. Raw Material Preparation
High-purity copper or aluminum is selected and cleaned to remove impurities, ensuring optimal conductivity.
2. Wire Drawing
The wire is drawn through specialized dies to achieve a precise flat shape. To meet various wire size requirements, we offer a range of wire drawing machines, including rough drawing, intermediate drawing machine a, and precision drawing models, ensuring optimal efficiency and precision for different production needs.
3. Annealing
The wire is heat-treated to relieve internal stresses, enhancing flexibility and conductivity. Temperature control is crucial to prevent defects.
4. Rolling
We utilize a 2-Hi cold rolling mill, featuring two horizontally positioned rolls, to precisely transform round wire into flat shapes with enhanced dimensional accuracy and surface finish.
5. Winding & Spooling
The insulated rectangular wire is carefully wound onto spools with controlled tension to prevent damage and ensure uniform winding.
6. Quality Control & Testing
The wire undergoes dimensional checks, electrical resistance tests, insulation integrity analysis, and magnetic property evaluations to meet industry standards.
7. Packaging & Shipping
After final inspection, the wire is coiled, labeled, and packaged to prevent damage during transportation.

Sky Bluer Industries China specializes in manufacturing wire flattening and shaping machines, as well as fine wire drawing machines.
The production process follows a precise and controlled sequence to ensure high-quality output:
Pay-off → Rough Rolling → Measuring Instrument → Tension Control → Rolling Mill → Measuring Instrument → Tension Control → Rolling Mill → Measuring Instrument → Tension Control → Take-up
Each stage is carefully monitored with measuring instruments and tension control systems to maintain precision, consistency, and optimal performance throughout the rolling process.
Magnet wire is classified by temperature rating, insulation type, and application.
1. Temperature Class: Ranges from Class 105°C (basic insulation) to Class 240°C (high-performance applications like aerospace and generators). Common classes include 130°C, 155°C, 180°C, and 200°C, each suited for different environments.
2. Insulation Type:
o Single Build (SB), Double Build (DB), Triple Build (TB), Quadruple Build (QB) – Increasing insulation thickness for better protection.
o Materials: Polyurethane (PU), Polyester (PE), Polyester-imide (EI), Polyimide (PI) for varying heat resistance.
3. Specialty Grades: Self-bonding wire, corona-resistant wire, and high-frequency wire cater to specialized needs.
Choosing the right grade depends on temperature demands, electrical stress, and industry-specific applications. Our equipment can meet all the above materials
