Sandblasting is suitable for aluminum alloy die castings where high consistency in appearance is required, and is often used before subsequent processes such as painting and electroplating. However, sandblasting itself does not provide functional enhancement; it primarily improves the surface finish.
The appropriate application of surface treatment technologies for aluminum alloy die castings helps to fully leverage the structural and performance advantages of aluminum die casting materials. Analysis of the characteristics and applicability of different processes shows that no single process is suitable for all products. Only by making targeted selections based on specific needs can the practical application requirements of aluminum die castings be better met.
