After aluminium parts are cast, they typically undergo post-processing to improve surface quality, mechanical properties, and fit for assembly:

  • Machining: To refine the dimensions and surface finish of the part (milling, drilling, grinding, etc.).
  • Heat Treatment: To enhance the strength and hardness of the casting by altering its microstructure (e.g., T6 heat treatment).
  • Surface Finishing: Including sandblasting, polishing, painting, or anodizing to improve surface appearance, durability, and resistance to corrosion.
  • Inspection and Testing: To ensure the casting meets the required standards, which may include dimensional checks, visual inspections, non-destructive testing (NDT), and mechanical property testing (tensile strength, hardness).
