How to improve the corrosion resistance of metal stamping parts

The current service life is carried out in accordance with industry standards, and theoretically it should have a service life of more than ten years. However, as an accessory for doors and windows, hardware accessories have a certain decorative effect, just like the discoloration and rough profile users are unacceptable. Rough, rust, discolored hardware users are also unwelcome. . The corrosion resistance of high metal stamping parts is imperative.

Improve the corrosion resistance of ferrous metals; currently the materials used in Anhui metal stamping parts are carbon steel, such as transmission locks, lining steel and so on. For carbon steel, how to improve corrosion resistance is the key to its service life. Due to frequent exposure to rain and sunlight, the surface that has been in contact with the profile in Shanghai for less than three years has been severely rusted. Referring to the relevant information, the first reason is that the surface of the PVC profile may liberate under the action of light and heat during the aging process. , which has a strong corrosive effect on the galvanized layer, which explains why the corrosion occurs on the contact surface with the PVC profile.

Generally speaking, China can only be called the largest country in the production of molds and can not be said to be a strong country in production. There is still a gap of 10 to 15 years between products and developed countries. At present, it is still dominated by medium and low grades. In recent years, the industry will continue to grow rapidly while exhibiting the following characteristics: products continue to develop in a larger, more sophisticated, complex and economical direction. The technological content will continue to increase, the manufacturing cycle will continue to shorten, and the production of stamping parts will continue to move. With the development of informationization, digitization, refinement, high-speed and automation, enterprises will further enhance their comprehensive strength and core competitiveness. With the improvement of product quality, the requirements for mold quality and life are getting higher and higher. The most effective way to improve mold quality and life is to develop and apply new mold materials and new heat and surface treatment processes to continuously improve performance and improve processing performance.

The mold used for stamping is called a stamping die, or a die for short. Dies are special tools for batch processing materials (metal or non-metal) into the required punches. Dies are very important in stamping. There are no dies that meet the requirements. Batch stamping production is difficult to carry out; without advanced dies, advanced stamping processes cannot be realized. The stamping process and the mold, stamping equipment and stamping materials constitute the three elements of stamping processing, and only when they are combined with each other can the stamping parts be obtained.
