China Aluminum Industry Net reports that extrusion dies used in industrial aluminum extrusion are subjected to extreme conditions, including high temperatures and intense friction, leading to significant wear. Although high-quality heat-resistant tool steels are typically selected for die materials, the traditional heat treatment methods fail to provide sufficient hardness, wear resistance, and thermal fatigue resistance. As a result, the service life of these molds remains relatively short. Additionally, the surface hardness of the mold is low, causing the working section's surface roughness to decrease over time. This leads to poor anti-adhesion properties, making it easy for material buildup or "stuffing tumors" to stick to the working area. These issues cause pitting, scratches, and surface imperfections on the extruded profiles, severely affecting their overall quality. Applying appropriate surface strengthening treatments to aluminum profile extrusion dies is one of the most effective ways to enhance their performance and extend their service life. Gas nitriding was an early method used for surface hardening of molds. However, due to its long processing time and the brittleness of the nitrided layer, the effectiveness in improving the durability of aluminum extrusion dies has been limited. Currently, China's surface treatment technology for extrusion molds still lags behind foreign advanced standards. With the rapid growth of the aluminum profile industry in recent years, especially in construction applications, there has been increased attention on the issue of surface hardening for extrusion dies. Researchers have started exploring new surface hardening processes to improve die performance and meet the growing demand for high-quality aluminum profiles.
