How to clean hardware stamping parts

1. The purpose of cleaning metal stamping parts is to remove surface stains, and different cleaning fluids need to be selected according to the cleaning object. There are two types of cleaning fluids: water-based cleaning fluids and solvent based cleaning fluids.

2. Hydrocarbon hardware cleaning agents have good effects in removing oil and grease, and have a corrosion inhibition effect on metals such as steel. There is no corrosion to equipment, copper, stainless steel, and other combinations of different materials during cleaning, and the operation is simple, safe, and reliable.

3. The main methods for degreasing and removing oil stains on hardware and metal include organic solvent method, chemical method, electrochemical method, and water-based cleaning agent cleaning method. The commonly used organic solvent trichloroethylene cannot completely remove polishing wax, especially metal oxides, carbides, and polishing materials on metal surfaces that cannot be effectively cleaned; Trichloroethylene not only has significant toxicity, but also has a tendency to hydrolyze when used improperly, and is corrosive to metals under wet conditions.

Hardware stamping parts cleaning category:

1. General industrial cleaning: General industrial cleaning includes the cleaning of vehicles, ships, and aircraft surfaces, which can only remove relatively coarse dirt.

2. Precision industrial cleaning: Precision industrial cleaning includes the cleaning of various product processing and production processes, as well as the cleaning of various materials and equipment surfaces, characterized by the ability to remove small dirt particles.

3. Ultra precision industrial cleaning: Ultra precision cleaning includes the ultra precision cleaning of mechanical parts, electronic components, optical components, etc. in the production process of precision industry, with the aim of removing extremely small dirt particles.
