1. The cleaning and drying work of the hinge in the early stage should be done as required, otherwise no matter how good the electroplating treatment is in the later stage, it will not be able to achieve the purpose of rust prevention. Some unscrupulous merchants use unclean water when cleaning or the drying operation is not done well, which will cause the hinges to rust.
2. The material of the hinge is not up to standard. Although many businesses in the market claim that the hinges they produce are made of 304 stainless steel, in fact, the chemical composition they contain cannot meet the national standard, so it will also cause the hinges to rust.
3. Consumers do not give the hinges good protection. For example, some cabinets are made of synthetic stone panels. If the hinges on the cabinets are not well sealed, the chemical composition of the synthetic stone will corrode the hinges and cause the hinges to rust.
