1. The wall of aluminum alloy die-casting parts is not suitable for being too thin, and problems such as under-casting and cold separation are prone to occur.
2. The choice of wall thickness for aluminum alloy die castings: under normal conditions of use, the wall thickness is not suitable to exceed 4.5mm, suitable for small and medium-sized castings: zinc alloy materials 1-3mm, aluminum and magnesium alloys 1.5-4mm, alloys Copper 2-4mm.
3. The wall thickness of aluminum alloy die castings should be symmetrical, which is beneficial to increase the additional condensation of the aluminum alloy liquid after "filling". It can prevent forging ground stress, shrinkage, cracks and other problems.
4. For a part of the thick-walled pipe in the aluminum die-casting product variety, ribs or cast inserts can be used to improve its physical properties and change its process performance.
Therefore, in the thick-wall design of aluminum alloy die-casting parts, it is not suitable to increase the thickness of the wall to improve the load-bearing capacity of aluminum alloy die-casting parts. When the thickness of the casting exceeds the required bottom thickness, the impact toughness decreases as the thickness increases. If the wall thickness of the casting is too large, it is easy to produce shrinkage porosity and pores, resulting in long initial setting time, large shrinkage porosity and difficult demolding.
The above is the whole content of the aluminum die casting manufacturer's introduction on how to determine the thickness of aluminum alloy die castings. I hope you can have a better understanding of it after reading it. If you have anything you want to know, please contact us.
