How to determine the thickness of aluminum alloy die casting parts.precision metal stamping parts suppliers

　　.Aluminum alloy die-casting wall is not suitable for too thin, large-scale too thin wall, prone to undercasting, cold insulation and other defects.

　　2. Choice of thickness of aluminum alloy die-casting wall: under normal conditions, the wall thickness is not suitable for more than 4.5mm, small and medium-sized casting parts are suitable for wall thickness: zinc alloy material 1-3mm, aluminum, magnesium alloy 1.5-4mm, alloy copper 2-4mm.

　　3. The thickness of aluminum alloy die-casting products should be symmetrical, which is beneficial to the additional condensation after the "filling" of aluminum alloy liquid. Can prevent the forging ground stress, shrinkage, crack and other shortcomings.

　　4. For a part of the thick wall tube on the aluminum die casting product variety, stiffened plates or cast inserts can be selected to enhance its physical properties and improve the process performance.

　　Therefore, in the thick wall design of aluminum alloy die casting parts, it is not suitable to choose the way of raising the thickness of the wall to improve the bearing capacity of aluminum die casting products. When the thickness of the cast exceeds the necessary bottom limit, its impact toughness will be reduced. The wall of casting parts is too thick, which is easy to cause shrinkage and porosity, and will lead to adverse conditions such as initial setting length, large shrinkage and then core pulling and demoulding in aluminum alloy die casting production process.
