What Is Aluminum Extrusion?
Aluminum extrusion is a manufacturing process where heated aluminum billets are pushed through a precision die to form continuous profiles with custom cross-sectional shapes. It is an efficient solution for producing lightweight, durable, and dimensionally consistent components with simple or complex geometries.
This process is widely used to manufacture custom aluminum products for construction, transportation, electronics, and consumer industries, including window and door frames, curtain wall systems, heat sinks, enclosures, rails, and structural components. Combined with machining, finishing, and fabrication operations, aluminum extrusion supports both prototype and production requirements.
Aluminum Extrusion Process
Aluminum extrusion produces profiles with defined cross-sectional geometries by forcing a heated alloy billet through a precision-machined die. At ZH Precision, the process follows a controlled sequence to ensure dimensional accuracy and material consistency, beginning with custom die fabrication matched to solid, hollow, or semi-hollow profile requirements, followed by billet preheating to a precise 400–500°C range to achieve optimal plasticity for forming.
Extrusion is executed using direct or indirect methods, selected based on alloy grade and target mechanical properties. Post-forming steps include controlled quenching, stretch straightening, and cut-to-length operations, with optional thermal treatments such as T5/T6 aging to enhance hardness, tensile strength, and dimensional stability.
Secondary processes, including CNC machining and surface treatments (e.g., anodizing, powder coating), are applied per specification. Each profile undergoes dimensional verification, surface defect inspection, and material performance testing before final packaging and shipment.
