The production process of glow plugs generally includes the following main steps:

• Material Preparation: Prepare all raw materials required for glow plug production, including metal wires, ceramics, insulating materials, etc.

• Metal Wire Processing: Process the metal wires (e.g., wire drawing, compounding) to make them suitable for manufacturing heating elements.

• Heating Element Fabrication: Process the metal wires into heating elements with specified length and diameter.

• Heating Element Installation: Assemble the heating elements onto ceramic or other insulating material brackets to form the core components of glow plugs.

• Encapsulation: Encapsulate the heating elements and brackets in insulating materials to ensure safe operation.

• Testing: Conduct performance tests on the finished glow plugs to ensure they meet quality standards.

• Packaging: Package the qualified glow plugs (after testing) for transportation and sales.
