The ceramic cartridge  is the heart of the faucet, and the ceramic disc is the heart of the cartridge. All components of WANHAI cartridges are produced in-house and the discs are handled with the utmost care, so every step of the production must be fully controlled to ensure that the finished product is accurate, durable and reliable.


It first selects the best raw material made by dry pressing, sintering process in high temperature oven, grinding, cleaning, drying and final surface inspection.


Seals are also produced in-house, including material mixing, stamping and vulcanization. 


No third-party suppliers of components are involved, only select raw materials sourced from around the world go into the factory.
