1. Precision Winding Wire (Copper / CCAW / Aluminum)
Sourced from top-tier brands. We use high-purity round or flat wire with exceptional temperature coefficients to ensure maximum conductivity and magnetic field efficiency.
2. High-Temperature Formers (Kapton / Glass Fiber / Aluminum)
Selected based on your thermal and mechanical requirements. Formers are precision-slitted and treated to withstand continuous high heat without deformation.
3. Aerospace-Grade Bonding Adhesives
Specialized thermosetting resins that lock the turns securely in place, preventing loose windings or coil rubbing even under extreme excursion and high power.
4. Lead-out & Reinforcement Papers
Durable, fatigue-resistant lead-out wires and high-strength reinforcement papers designed to protect solder joints from vibration stress.

Frequently Asked Questions
Quick answers regarding custom specifications, MOQ, sampling, and global shipping.
Can you produce voice coils according to custom technical drawings?
Yes, absolutely. We specialize in OEM and ODM custom manufacturing. You can provide your detailed blueprints, CAD drawings, or specs (such as ID, wire size, height, and resistance), and our engineering team will review and manufacture accordingly.
What is your Minimum Order Quantity (MOQ) for custom voice coils?
To support both growing brands and large-scale speaker manufacturers, our MOQ is flexible depending on the model and tooling requirements. We also support rapid prototyping and small-batch trial orders.
What wire materials and former options are available?
We offer high-purity Copper, Copper-Clad Aluminum Wire (CCAW), and pure Aluminum wire (both round and edge-wound flat wire). For formers, we supply Kapton, Glass Fiber, and Aluminum with high-temperature resistance ratings up to 220°C–300°C.
How long does it take for custom samples and mass production?
Standard custom samples typically take 5 to 7 working days to produce and dispatch. Mass production lead times range from 15 to 25 days depending on the order volume and complexity.
How do you ensure safe shipping for delicate voice coils?
We use anti-static, moisture-proof custom blister trays and robust export-grade cartons to prevent any deformation or vibration damage during international air or sea shipping.
