The glow plug production process generally includes the following key steps:

Material Preparation: Prepare the various raw materials required for glow plug production, including metal wire, ceramic, and insulating materials.

Wire Processing: Process the metal wire through processes such as drawing and laminating to create the heating wire.

Resistance Wire Fabrication: Wire is processed to a predetermined length and diameter to form the heating wire.

Resistance Wire Installation: Attach the heating wire to a support made of ceramic or other insulating material, forming the core component of the glow plug.

Packaging: Encapsulate the heating wire and support in insulating material to ensure safe use.

Testing: Performance testing is performed on the produced glow plugs to ensure they meet quality standards.

Packaging: Qualified glow plugs are packaged for transportation and sale.
