Can die castings be post-processed?

Yes, die castings usually require some post-processing to further improve dimensional accuracy and surface quality. Common post-processing techniques include:

• machining: Such as milling, turning, etc., for resizing parts and removing burrs or irregular surfaces.
• surface treatment: Such as sandblasting, polishing, anodizing, etc., used to improve the appearance quality and corrosion resistance of parts.
• hot treatment (e.g. of metal): To improve the hardness and strength of a part by annealing, quenching, etc., to meet specific work requirements.
