Aluminum alloy gravity casting in the process of work with the degree of complexity of its casting shape, the casting mold of its products are also different, even if it is the same part, using different casting processes, mold forms are often different, but in any case, aluminum alloy gravity casting mold or have their commonalities.

Aluminum alloy gravity casting in the operation must choose the appropriate casting process, the casting process is directly related to the quality of casting and process yield. Some domestic mold manufacturers have begun to use solidification simulation to assist the casting process design, through the computer simulation of the filling and solidification process, it is found that the casting defects of hot-bound aluminum alloy casting parts are easy to be overcome, which is very important and effective to improve the reliability of the casting process design and effectively prevent unnecessary rework in the debugging process of the mold.
The mold should have a good heat capacity. The thicker mold frame and module that meet the requirements are not only an effective guarantee of the life of the mold, but also play a very important role in the adjustment of the temperature field in the continuous working process of the mold. The mold should have a more reliable cooling system and extraction system. Through cooling, not only can effectively improve labor productivity, but also can adjust the casting temperature field, control the casting cooling speed, and then affect the internal structure and grain size of the casting, to achieve the purpose of effectively controlling the casting mechanical aluminum alloy casting energy.
As the name suggests, gas extraction is to artificially exhaust the gas inside the mold cavity to the outside of the mold cavity to reduce the possibility of porosity defects in the casting. At the same time, by installing the exhaust plug can also adjust the mold temperature of the local small area, which has a very important role in preventing and overcoming the cracking and shrinkage of aluminum alloy.

It is necessary to have a mold positioning device that matches the casting machine and a convenient mold installation system. The positioning device is not only the key to ensure the size of the casting, reduce the seam and burr, but also the key to ensure the normal work of the casting machine, it can be said that the mold has no good positioning device, no good qualified castings.
The composite die-cast aluminum radiator has the following advantages in structure and performance:
1, corrosion resistance, high pressure resistance, durable, suitable for different water quality heating systems.
2, simplify the heat transfer thermal resistance and expansion tube composite process, improve the heating system overall heat dissipation performance.
3, excellent thermal performance, high metal thermal strength.
4, to avoid the heat flow smoke wall, and heat dissipation effect.
5, free assembly, flexible assembly, easy installation.
6, radiator body surface no harmful substances volatilization, will not cause harm to the environment and human body.
7, simple, beautiful, generous, can live in harmony with die casting, symbiosis, safe die casting reliable
