Is aluminum fin stamping oil seriously polluted? Oil selection is the key!
December 31, 2022
The aluminum fins of air conditioners are the basic components of condensers and steam generators, which are mainly used for heat dissipation and are made by stamping process. The materials used are generally aluminum and aluminum foil. The thickness is about 0.10-0.20mm, which is processed by high-speed punching through punching, flanging, stretching, thinning, shearing and other processes.
Aluminum foil is thin and easy to deform. In the process of flanging and thinning stretching, if the lubrication is not enough, it will lead to flanging cracks, cracks, scratches and other problems at the connection between the flanging and the body. In addition, the air conditioner condenser pipe is in close contact with the flanging on the aluminum fin of the air conditioner, and the stamping oil on the contact surface is difficult to remove, so the aluminum fin stamping oil is required to have good volatility. Of course, the lubricity of aluminum fin stamping oil is also very important. In the process of aluminum fin stamping, there is not only fluid lubrication, but also boundary lubrication. The lubrication between die and metal is maintained by boundary lubrication film. In order to ensure that there are no burrs, scratches and other problems in the processing of air conditioner aluminum fins, aluminum fin stamping oil must have a certain degree of lubrication. In addition, in order to prolong the service life of the die, the aluminum fin stamping oil must not only have lubricity, but also have certain extreme pressure performance. Corrosion resistance. The aluminum fin stamping oil you choose also needs certain corrosion resistance, otherwise it will oxidize your aluminum foil. The chemical properties of aluminum elements are relatively active, and electrochemical corrosion is easy to occur. The correct selection of aluminum fin stamping oil can maximize the service life of the mold by more than 40%, which is volatile and free of cleaning. The imported anti-wear agent, extreme pressure agent and oily agent are used to improve the surface quality of the air conditioner aluminum fin stamping.
