5 , Ceramic production
 

1, the purchase of ceramic powder back through the ball mill grinding, grinding out the appropriate size and density of particles.
 

2, tune the good particles through our pipeline transportation, delivery to the granulation tower.
 

3, granulation tower is our unique ceramic production process - isostatic pressing technology, mainly grinding the particles with isostatic pressing technology directly dry forming, so that there is no air between the particles and the gap between the particles to ensure that Density. Isostatic technology At present, except for our industry only NGK, DENSO, champion, Bosch and the torch has a set of technology, the technology than the traditional hot melt technology, high pressure, resistance to wear, high temperature ability times several times.
 

4, after the formation of particles through the constant temperature tunnel kiln, which is through the natural gas calcination molding - the temperature up to 1580 degrees, higher than the engine normal operating temperature (500 degrees -800 degrees). 5, after the ceramic insulator after the glaze, make it smooth, bright. And then printed on the outside of the corresponding printing.

6 , Assembly production

1, through the automatic powder machine, the amount of resistance powder (with Bosch the same supplier) + center electrode + screw + expansion powder into the finished ceramic insulator inside, after heating, the internal structure of the spark plug has been formed.

2, after forming the need for internal voltage test, after 25000V high voltage on each of the detection of whether the breakdown of insulation and leakage, excluding unqualified products.

3, through the hot-pressing assembly line, the insulator and iron shell welding. And we are using hot riveting welding technology, this technology is currently Bosch's spark plug is also being used. Because the welding is the need for heating, so in the hexagonal screw will be under a circle of light blue halo. The NGK is the use of cold riveting technology, so the insulator and iron shell where there will be a small layer of pale white powder.

4, after assembly into the finished product, will be simulated air pressure detection, simulation of the engine cylinder operating pressure, the finished product installed into the test center electrode and the distance between the side of the electrode to achieve the ignition requirements of the engine to detect its performance and quality.

5, the detection of quality problems of finished products, for packaging.
