‌Ignition Coil‌

The ‌ignition coil‌ is the core component of the gasoline engine ignition system. It steps up the vehicle's low-voltage electricity to tens of thousands of volts of high voltage, and ignites the mixed gas in the cylinder through the spark plug. Inside the coil are the primary winding and secondary winding, which generate high-voltage pulses based on the principle of electromagnetic induction. The main types of ignition coils include pencil ignition coils, dual-output ignition coils, and modular high-voltage ignition coils. The voltage boost performance and insulation strength of the ignition coil directly determine the engine's combustion efficiency, power output and emission levels. Under the precise control of the Engine Control Unit (ECU), the ignition coil must complete charging and discharging within an extremely short period of time.

I. Common Ignition Coil Winding Types

Layered Segmented Winding‌

Split the secondary winding into insulated sections to lower inter-layer voltage gradient and avoid partial discharge. Requires auto paper padding, segmented turn counting and multi-station synchronous operation.

Parallel Winding with Tap‌

Double-wire parallel winding on primary/secondary, with pre-set taps for adjustable ignition energy or signal feedback. Supports independent dual-wire tension control and auto tap positioning.

Full-Auto Tape Wrapping Winding‌

Auto-apply high-voltage resistant tape after each winding layer for solid inter-layer insulation. Integrated with tape feeding, break detection and auto tail pasting.

II. Benefits of Automated Ignition Coil Production Line

Reliable inter-turn insulation, consistent withstand voltage‌

Precision wire arrangement and constant tension control eliminate manual winding defects like overlapping turns or scratched film. Paired with auto paper padding, it delivers high pass rate in inter-turn HV tests.

Damage-free fine secondary wire winding‌

Low-inertia tension system with zero start/stop impact, plus ceramic guides and anti-static setup, cuts fine wire breakage and enamel film scratches drastically.

Full-auto line for high consistency & output‌

One line integrates primary/secondary winding, padding, taping, soldering and testing. It replaces multi-step manual work, keeping batch electrical parameters fully compliant with automotive standards.
