- Suitable for automated production processes
- Good flexibility for high-speed winding
- Strong resistance to tension and breakage
- Reduces processing steps (no varnish/baking required)
- Lowers production time and cost
- Simplifies coil assembly process
- Micro motors
- Transformers
- Voice coils
- Relays
- High-frequency coils
Q1: Is soldering required to remove enamel?
A1: UEW enamel typically supports direct soldering under appropriate temperature conditions, depending on process requirements.
Q2: How is this self-bonding magnet wire processed?
A2: This self-bonding magnet wire can be activated either by heat and by solvent treatment. Heat bonding uses hot air, ovens, or electrical current to soften the bonding layer, while solvent bonding uses alcohol-based or specialized solvents to fuse adjacent turns of the winding.
Q3: Can you provide customized dimensions?
A3: Yes. Customized diameters, color, insulation build, and spool packaging can be supplied according to customer requirements.
Q4: What information is required for a quotation?
A4: To provide an accurate quotation, please share the wire dimensions, insulation type, thermal class, required quantity, packaging requirements, and destination country.
Q5: If the MOQ is not met, can it still be produced?
A5: If the order quantity does not meet the MOQ requirement, we can also produce it for you, but the price will be higher than the MOQ price. Generally, it is calculated based on 3-5 times the MOQ unit price multiplied by the order quantity that you need, and plus a startup/module fee of 1,500 RMB. (If the total price of samples is higher than the MOQ price, then we will follow the total price of MOQ)
