PRODUCTION PROCESS

AUTOMATIC CNC MACHINE FOR METAL SHELLS

Using CNC machined imported from Germany to process various specifications of the metal shell, so that each size meets the design requirements of the drawings.

AUTOMATIC WELDING MACHINE FOR SIDE ELECTRODES

Fully automated line for welding of ground electrodes with electronic control.

BURNING OF THE INSULATOR

Sintering process in which a qualitative change occurs in the corundum body. A porous, fragile raw insulator turns into a hard, impervious, electrically resistant insulator.

ASSEMBLY OF INSULATOR

Automatic assembling of the insulator with the individual components – center electrode, resistive seal and terminal pin.

FINAL ASSEMBLY OF ALL COMPONENTS

Automatic assembling of the finished insulator and the individual components –Metal shell, Inner and Outer Washer.

QUALIFIED GAP CORRECTION BY CCD VISUAL INSPECTION SYSTEM

The fully automatic assembly line with the most advanced CCD visual inspection system, which can accurately detect and adjust the gap of 0.5um，ensure that the ignition gap tolerance of the spark plug is controlled at ± 0.05mm, which is top important key for the quality of iridium and platinum spark plugs.
