Deformation is a common issue in aluminum alloy die-casting production. It affects product appearance and reduces dimensional accuracy and performance. Therefore, adequate measures must be taken to mitigate this problem.
Adjust parameters such as machine pressure, molten metal temperature, and injection speed to ensure uniform cavity filling, reducing porosity and shrinkage. Strictly regulate pouring temperatures and pressure to prevent deformation due to improper parameter settings.
Adjust ejection positions and increase the number of ejector pins in open areas to minimize stress concentration during demolding. Implement appropriate mechanical processing and heat treatment to reduce internal stresses.
Additionally, post-processing of castings should not be overlooked. Severely deformed castings can be corrected through calibration or reshaping. Implement rigorous quality inspections during production to promptly identify and address deformation issues, preventing defective products from advancing to subsequent stages.
