Aluminum extrusion is a widely used manufacturing process that allows for the creation of complex shapes and profiles. However, surface defects can significantly impact the quality and performance of extruded products. Understanding the causes and implementing effective prevention strategies is crucial for manufacturers aiming to minimize these defects. This article explores common aluminum extrusion defects and remedies, providing insights into how to achieve high-quality extrusions.

Aluminum extrusion is a widely utilized manufacturing process that shapes aluminum into various profiles by forcing it through a die. While this process offers numerous advantages, including versatility and efficiency, it is not without its challenges. One of the most significant issues faced by manufacturers is the occurrence of surface defects in aluminum extrusions. Understanding how to identify and rectify these defects is crucial for maintaining product quality and meeting customer expectations.
