1.The quality of the mill affects the density and hardness of the toilet, and these two factors are the key indicators of the quality of the toilet. The good factory uses a large-tonnage ball mill, which is more powerful and can grind finer than the small-tonnage ball mill of ordinary manufacturers. The ball milling time of a good factory is also longer, so that the powder can be ground finer. Only by grinding the powder finer, the pressed billet will be denser, and it will be more wear-resistant and anti-fouling.
2.A good toilet factory high-pressure grouting adopts a high-pressure grouting machine, which can be raised to a working pressure above 4500psi (300kg/cm2) within 3-6 seconds, and the liquid water-stopping agent can be effectively poured into 0.1mm. The efficiency is more than three times faster than the traditional technology, and the waterproof and leak-proof effect is more durable and effective. But the high-pressure grouting machine is very expensive, and small manufacturers do not have it, so the toilet has osteoporosis and there are air bubbles in it.
3.Put to drying room around 8 hours, reduce the moisture of the ceramic body and improve the firing quality.
4.Fettling ,we need to ensure that the ware is well finished and free from cracks and pinholes, the surface to be flat and smooth.
5.De-dusted and sponged smooth the formed toilet.
6.Our skilled worker was checking every toilet by hand to keep it straight and flat,then they will check half-finished produc wares one by one to ensure no flaw.
7.Automatic spray glazing with imported self-cheaning glaze,it make the surface of each product flat and smooth.
8.Final check the half-finished ware.
9.At present, in the whole sanitary ware industry, high-temperature kilns are roughly divided into two types: the first is: traditional high-temperature kilns that rely on manual control account for more than 80% of the industry. Unstable quality. The second is: imported computer-controlled high-temperature kiln, the temperature in the kiln is as high as 1280 °C, the temperature difference at any point in the kiln is less than 5 °C, the cost is high, and the quality of the produced products is stable.
10.Visual inspection,first inspection step after releasing form the kiln,classify the wares,if the surface with spot,crazing,fire crack,pinhole that will be unacceptable and then make sure all the install holes are standard and round enough.
11.Air pressure ware leakage test,We have blocked the inlet&outlet hole of the toilet bowl,air is inserted from the top,any invisible crack inside can be dectived by measuring the air the pressure.if air doesn't leak out with a certain level of air pressure bumped in from outlet hole,then it mean water will not leak from the bowl.
12.Flushing function test(Full flush test 3 times;Half flush test 3 times)
①water seal height test
②Flush 16 pcs toilet papers,all washed off
③toilet with color ink test,all washed off
④Flush 100 PP balls,minimum flush 43 PP balls
⑤splash test
13.Final inspection,make sure there is no glaze damage.
14.Packing,each piece will be packed in one 5-ply or 7-ply export carton,extra packing with fixed styrofoam.
