❖ This machine employs CNC automatic face-probing and datum-setting technology, as well as a proprietary, adjustment-free integral mechanical structure.

❖ The motion controller is paired with a specialized closed-loop intelligent fine-tuning dense-winding control technology. Its patented closed-loop wire-laying sensor utilizes digital sampling technology, offering robust anti-interference capabilities, precise control, and superior wire-laying performance.

❖ Closed-loop tension control: Prevents wire breakage, ensures high equipment utilization, maintains stable impedance values, and offers high reliability; Neat-array winding reduces material costs, supports rapid adjustments, and lowers maintenance expenses.

❖ This machine is capable of continuous operation and is suitable for winding linear motors, frameless voice coils, self-bonding coils, air-core coils, mobile phone speaker coils, high-end loudspeaker coils, laser head coils, SMD coils, IC card coils, computer hard drive coils, toy coils, camera coils, retail security tag coils, proximity card coils, alarm system coils, vibration motor coils, card reader/writer coils, sensor coils, dual-gang coils, quad-gang coils, various types of irregularly shaped air-core coils, micro-motor coils, and more.

❖ This machine is convenient and simple to operate, requires no human supervision, and offers high efficiency and high speed.

❖ Supports two configuration modes—equal-turn winding and unequal-turn winding—enabling more precise, orderly winding.

❖ This machine can operate in either fully automatic or manual mode.

WHY WISRSUN?

❖ Closed-Loop Tension Control: The controller is capable of programming and monitoring every dual-motor active servo tensioner within the system, and monitors and uploads the tension status of the entire production process in the form of data.

Our standard MOQ is 500 pcs for most coil types. For first-time customers or prototype evaluation, we accept small trial orders of 10-50 pcs. MOQ may vary by product complexity. Contact us for a specific quote.

Yes. Samples are available within 5-7 business days after engineering confirmation. A nominal sample fee applies, which is credited toward your first mass production order.

You can email drawings such as PDF, DWG, or STEP files, or fill out our inquiry form. If you do not have drawings, a written description or physical sample is also acceptable.

We can wind wire as fine as 0.01mm using Zongheng CNC precision winding machines with automated tension control.

Yes. Our special-shaped coil series handles non-circular and irregular geometries. Submit your drawings and our engineering team will assess feasibility.

Standard options include bare copper wire, enameled copper wire, and Litz wire. Custom alloy or coated wire options are available on request.

Yes. Provide your target inductance, frequency, and DC resistance requirements, and we will calculate and wind to specification.

WIRESUN is ISO 9001 certified. Products can ship with test reports and COA. Third-party inspection can be arranged upon request.

All coils are wound on CNC machines with precision control. Each production batch undergoes electrical testing, including inductance, DCR, and impedance checks.

Standard documentation includes packing list, commercial invoice, Certificate of Analysis, and electrical test report. RoHS/REACH documents are available upon request.

We ship worldwide. Regular destinations include Southeast Asia, Europe, the Americas, the Middle East, and Russia. Express and sea freight options are available.

Standard terms are 30% T/T deposit upon order confirmation and 70% balance before shipment. L/C is accepted for larger orders, and Western Union is available for sample fees.

Standard products usually take 15-20 business days. Complex custom coils generally take 20-30 business days. Final lead time is confirmed at quotation stage.
