How to determine the thickness of aluminumalloy die castings?

In the design process of aluminum alloy diecastings, many customers are uncertain about the thickness of aluminum alloy die castings, and they do notknow how thin the thickness of aluminum alloy die castings can be.

1. The aluminum alloy die-cast product wall is also not suitable fortoo thin, large-scale and too thin walls are prone to defects such asunder-casting and cold partition.

2. The choice of wall thickness foraluminum alloy die-casting products: under normal conditions, the wallthickness is not suitable to exceed 4.5mm, suitable for small and medium-sizedcastings: zinc alloy material 1-3mm, aluminum and magnesium alloy 1.5-4mm,alloy copper 2- 4mm.

3. The thickness of aluminum alloy die-casting products should be uniform,which is beneficial to the additional condensation of aluminum alloy liquidafter "filling". It can prevent the disadvantages of forging groundstress, shrinkage porosity and cracks.

4. For the thick-walled pipe part of thealuminum die-casting product variety, ribs or cast inserts can be selected toenhance its physical properties and improve process performance.

Therefore, in the thick wall design ofaluminum alloy die-casting parts, it is not suitable to choose the method ofraising the thickness of the wall to increase the bearing capacity of aluminumdie-casting products. When the thickness of the casting exceeds the necessarylimit, its impact toughness will decrease accordingly. Excessive thickness ofthe silicone casting wall willeasily cause shrinkage porosity and air vents, and will cause the initialsetting of the aluminum alloy die-casting production process to cause longinitial setting, large shrinkage, core pulling, difficult demolding and otherunfavorable conditions.

We focus on aluminum alloy die-castingcustomization and have many experienced die-casting production teams. We canalso provide you with reasonable and effective suggestions during the processof thick wall control of aluminum alloy die-casting parts!
