Today, kitchen faucets manufacturers introduces the steps of the faucet spool processing:
1. Precision casting spool.
2. Machine tool processing.
3. Assemble rubber ring and plastic parts.

Common faucet spools have steel ball spools and ceramic spools. The steel ball valve core has good resistance to pressure, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. Compared with the steel ball valve core, the ceramic valve core is more resistant to heat and wear.

At the same time, the ceramic valve core itself has a good sealing performance, so that it can achieve a high number of opening resistances, and the nozzle does not leak due to the wear of the valve core. The faucet with ceramic valve core is more comfortable and smooth in hand, and it is quick to open and close. Since the spool is inside the faucet, the consumer can't see the spool when purchasing, but the consumer can simply judge whether the spool is good or bad according to the feel when turning the handle. In general, the consumer turns the handle up, down, left, and right. If it feels light and has no blockage, the spool is better.
