MANUFACTURING & QUALITY

Igniter Manufacturing Process

Consistent igniter performance depends on control throughout the manufacturing process — from incoming materials and ignition-head preparation to electrical connection, resistance inspection, batch testing, and final packaging.

Ignition-Head Process
Material Preparation & Incoming Inspection → Copper-Clad Board Preparation → Bridge-Wire Welding → Ignition Composition Application → 100% Initial Resistance Inspection

Parallel Lead-Wire Preparation
Lead wires are prepared separately according to the required conductor specification, insulation, length, color, and configuration.

Final Assembly & Verification
Component Assembly & Electrical Connection → 100% Second Resistance Inspection → Daily Batch Ignition Testing → Final Visual Inspection → Packaging & Batch Release

The exact manufacturing sequence may vary depending on product structure, application requirements, and customer specifications.

Electrical Testing & Quality Control

Electrical checks are carried out during production rather than relying only on a final inspection.

Resistance is checked at two critical production stages, allowing abnormal values to be identified before the product proceeds further through assembly or release.

Resistance Inspection
Each ignition head undergoes 100% resistance inspection after ignition-head preparation. A second 100% resistance inspection is carried out after welding and final assembly.

These two inspection stages help identify variation related to the ignition element, electrical connection, lead wire, or assembly process.

Assembly & Connection Inspection
Welding points, electrical connections, and product structure are inspected during production. For products using connectors, terminals, PCB structures, or application-specific assemblies, relevant connection points are checked as part of the same process.

Sample Ignition Testing
Daily batch ignition testing is conducted using samples from production batches under defined test conditions.

The purpose is to verify that electrical measurements and actual ignition performance remain consistent with product requirements.

Final Inspection
Before packaging, finished products are checked for visible defects, incorrect assembly, configuration errors, and other issues that could affect use or shipment.

Materials & Component Control

Lead wires, conductors, PCB materials, terminals, connectors, and other components can affect resistance, connection stability, assembly quality, and suitability for the intended application.

Incoming materials and components are therefore reviewed before entering production.

Lead-wire configuration can vary by:

• Length
• Conductor specification
• Insulation
• Color
• Application requirement

Wire selection is evaluated together with the electrical and application requirements of the finished igniter.

PCB & Ignition Components
PCB-based and other structured igniters use different combinations of substrates, conductive materials, ignition elements, and assembly methods. Final construction is selected according to product design and intended application.

Connectors & Terminals
Connector and terminal selection is matched to the igniter structure, lead wire, firing equipment, installation method, and operating environment.

OEM & Custom Igniter Manufacturing

Many ignition applications require more than a standard product configuration.

For OEM and application-specific projects, key specifications are reviewed before production so the product can be manufactured around the actual requirement rather than modified after assembly.

Configuration can include:

• Lead-wire length and conductor specification
• Wire color and insulation
• Resistance requirement
• Connector or terminal type
• Igniter structure
• Packaging
• Labeling and branding
• Selected semi-finished supply formats

Semi-Finished Supply

For qualified B2B customers with their own assembly capabilities, selected semi-finished ignition components can also be supplied. Availability depends on the product, assembly process, intended application, and applicable compliance requirements.

Application Review

• Intended application
• Required electrical characteristics
• Lead-wire and connector requirements
• Firing equipment
• Installation or operating conditions
• Required supply format
• Expected order volume

Firing System Support

For applications requiring matched ignition and firing equipment, AURAN can support product selection and system configuration based on the igniter type, electrical requirements, operating conditions, and intended application.

Compatibility requirements are reviewed before system configuration or supply.
