Manufacturing Excellence: High-Precision Automotive Clutch Coils

Automotive clutch coils are essential components used to control the engagement and disengagement of air conditioning compressors, cooling fans, and mechanical superchargers. While they may appear simple, these coils are high-tech components engineered for high reliability, extreme environment resistance, and superior performance.

The winding of these coils is a precision manufacturing process centered on four core principles: Compactness, Alignment, Insulation, and Durability. We ensure peak quality through rigorous tension control, precise turn counts, advanced insulation treatments, and Vacuum Pressure Impregnation (VPI).

Pre-Winding Preparation

Material Inspection: Only specified grades, diameters, and insulation classes of enameled copper wire are used.

Equipment Calibration: Our winding machines undergo precision calibration to ensure tight, neat layers without overlaps or gaps.

The Winding Process

Precision Tension Control: Excessive tension stretches the wire and risks damaging the insulation film.

Neat Layering: Coils must be wound layer-by-layer with zero gaps.

Exact Turn Count: High-accuracy counters ensure every coil has the identical number of turns.

Post-Winding Treatment and Quality Control

Welding and Lead Securing: Solder joints must be robust and smooth.

In-Line Insulation Testing: We perform Inter-turn Insulation Tests and Insulation Resistance Tests.

Vacuum Pressure Impregnation (VPI): Coils are cured in a vacuum tank to enhance mechanical strength and corrosion resistance.
