China Die Casting Supplierintroduces why aluminum alloy die castings are deformed:

There are two characteristics of the deformation of aluminum alloy die castings: one is the overall or local deformation, and the other is that the geometry of the die casting does not match the drawing.

The reasons for the deformation are poor casting structure; the premature opening of the mold, resulting in insufficient rigidity of the casting; improper setting of the ejector rod, resulting in uneven force during ejection; improper gate position or too thick gate, which is easy to remove the gate Deformation: The local rough surface of the mold causes high resistance, and the product deforms when ejected; the temperature of the mold is too high, causing the casting to not completely solidify, or the ejection force is too large, causing product deformation.

For the problem of die-casting deformation, the solution is naturally to prescribe the right medicine, such as improving the structure of the casting; reasonably adjusting the mold opening day and holding pressure; reasonably setting the ejection position and the number of ejector pins; changing the gate position to reduce the gate thickness; strengthening Mold surface treatment to reduce demolding resistance; to control local mold temperature to maintain mold thermal balance.
