How to prevent cracks and scratches on aluminum alloy extrusion dies?

Translation: "Cracks and scratches on aluminum extrusion dies are caused by cracks in the mold, resulting in sharp projections at corners or acute angles of the extruded parts. They often appear at corners of extruded aluminum alloy products, and are difficult to detect visually at acute angles, so they are typically found by touch.

Methods to eliminate cracks and scratches on aluminum extrusion dies include:

Inspecting the mold.

Detecting them early through inspection of the extruded parts.

During mold design, minimizing stress at corners as much as possible.
