Under the trend of continuous economic development, the northern cast aluminum industry with a long history and culture is also constantly innovating and developing. Castings are widely used in daily life and various fields. Compared with this, we are not unfamiliar with it. These different casting properties also make them glow and heat in different fields. In any case, the northern aluminum casting process is very important and can not be ignored. Today, Xiaobian will introduce to you what you should pay attention to in the process of northern aluminum casting.
If you want to punch aluminum parts well and reduce the defect rate, you must first do a good job in workshop management, especially clean the mold, punch table, assembly line and packaging materials, and ensure that there are no sharp sundries and dirt. The mold shall be cleaned and rectified regularly, and the top and bottom of the mold shall be cleaned without sundries.
Non ferrous metals made of cast aluminum in the north have the characteristics of absorbing gas. The solubility of absorbed gas increases rapidly with the increase of alloy temperature. Therefore, in addition to correctly controlling the whole melting and pouring process, the heat preservation of alloy liquid at high temperature should be minimized to avoid overheating of alloy liquid. The alloy that is easy to absorb should be melted under the protection of covering agent. In this way, the generation of pores and pinholes can be avoided.
In addition, in order to obtain good castings with stable quality when casting aluminum in the north, the mold temperature must be strictly controlled within a certain process range, which requires the mold cooling and heating device to ensure that the mold works within a constant temperature range.
