After the metal stamping parts are processed, they need to be cleaned in time. In fact, there are two main categories of metal stamping parts cleaning, namely industrial cleaning and precision industrial cleaning. General industrial cleaning includes the cleaning of the surfaces of vehicles, ships and aircraft, and precision industrial cleaning includes the process cleaning of various products and the surface cleaning of various materials and equipment. The cleaning fluids are divided into two categories: water-based cleaning fluids and solvent-based cleaning fluids.
First of all, the main methods of deoiling metal stamping parts include organic solvent method, chemical method, electrochemical method, water-based cleaning agent, etc. Trichloroethylene is a common organic solvent, which cannot completely remove glossy wax, especially metal oxides. The carbides and brighteners on the metal surface cannot be cleaned effectively. Trichloroethylene is not only toxic, but also easy to hydrolyze if used improperly. Trichloroethylene will corrode metal stampings in wet conditions.
Secondly, the use of hydrocarbon-based hardware cleaning agents has good degreasing and degreasing effects. When cleaning, it has a good degreasing effect on metal stamping parts and other metal parts. It has no corrosion to copper, stainless steel and other materials, and is easy to operate, safe and reliable.
The third is the use of ultra-precision industrial cleaning for metal stamping parts. Ultra-precision industrial cleaning refers to the ultra-precision cleaning of mechanical parts, electronic parts and optical parts in the process of precision industrial production to remove particulate matter in dust.
