310500 ignition coil for Chevrolet

Description

Ignition coils play a very important role in the engine system. Therefore, we pay attention to the following important aspects in the production of ignition coils:

1. Material Selection

   • Use high-quality copper wire for precise winding and stable conductivity.

   • Select heat-resistant plastics (PA66) for housings to withstand engine temperatures.

   • Ensure insulation materials (e.g. epoxy resin) meet voltage resistance standards.

2. Precision Winding Process

   • Maintain uniform winding of the primary and secondary coils to ensure consistent high-voltage output.

   • Use automated winding machines to reduce human error and improve efficiency.

3. Core Quality and Design

   • Choose ferrite or laminated iron cores with high magnetic permeability.

   • Proper core design ensures maximum energy transfer and spark efficiency.

4. Encapsulation & Insulation

   • Fill coils with high-quality epoxy resin to protect against moisture, vibration, and thermal shock.

   • Ensure air bubble-free encapsulation to avoid short circuits or insulation breakdown.

5. Terminal and Connector Integrity

   • Use corrosion-resistant terminals and ensure a secure fit with OE connectors.

   • Apply strict dimensional tolerances for compatibility and leak prevention.

6. Testing and Quality Control

   • Conduct high-voltage testing, leakage testing, resistance testing, and heat aging tests.

   • Implement 100% testing before packaging to reduce failure rates in the field.

7. Compliance with Standards

   • Meet or exceed IATF 16949, and other relevant quality standards.

   • Ensure compatibility with emission regulations and vehicle onboard diagnostics (OBD).
