Aluminum Extrusion in Vietnam: Process, Shapes, and Industry Growth

What is Aluminum Extrusion in Vietnam?

Aluminum extrusion in Vietnam is a key manufacturing process that shapes heated aluminum billets into strong, lightweight, and versatile products. Factories heat aluminum billets until they become malleable, then press them through precision dies to create profiles with the desired cross-section. After extrusion, workers cut the aluminum into specific lengths and may add machining or surface finishing to meet final product requirements.

Because extrusion combines speed, precision, and strength, this method is especially suitable for large-scale production. Industries such as construction, automotive, aerospace, and renewable energy increasingly rely on aluminum extrusion in Vietnam to produce durable, cost-efficient components.

Shapes of Extruded Aluminum

Aluminum extrusion produces continuous lengths of material with consistent cross-sections. Depending on design needs, products fall into three main categories:

• Solid extrusions – profiles with no enclosed voids, such as beams, rods, or angles.
• Hollow extrusions – profiles with one or more openings, such as tubes and rectangular channels.
• Semi-hollow extrusions – shapes that are partly enclosed, allowing more complex geometries.

Thanks to this flexibility, Vietnamese factories manufacture a wide variety of extruded shapes including channels, pipes, rails, and custom profiles for specialized industries. Consequently, aluminum extrusion in Vietnam provides both standard and tailor-made solutions for global buyers.

Steps of the Aluminum Extrusion Process

To understand how aluminum extrusion in Vietnam works, let’s break down the typical steps involved:

1. Die Preheating – Technicians preheat the extrusion die to 450–500°C before loading it into the press. Proper heating ensures stability and accuracy during production.
2. Billet Preheating – Aluminum billets are heated to 400–500°C until they reach a malleable state, making them ready for extrusion.
3. Lubrication – Workers lubricate the billet to prevent sticking between the billet and the ram.
4. Billet Loading – The billet is placed into the container, and the ram begins to apply pressure.
5. Extrusion – As pressure increases, the billet flows evenly across the cavity and presses against the die, creating the desired profile.
6. Runout Table – The newly extruded profile emerges from the press and moves along a conveyor called a runout table.
7. Quenching and Cooling – The extrusion passes through a quench section with water or air to cool evenly before reaching room temperature.
8. Stretching – Operators correct any distortions and ensure the profile meets dimensional accuracy by using stretchers.
9. Cutting and Heat Treatment – Finally, the extrusion is cut into lengths between 8 and 21 feet. At this stage, profiles typically reach T4 temper. T5 or T6 tempers can be achieved through further aging in specialized ovens.

Because each step requires precision, Vietnamese factories follow strict quality control standards to ensure consistent results for international buyers.

Aluminum Extrusion in Vietnam: Industry Strengths

Vietnam has quickly developed into a reliable hub for aluminum extrusion thanks to advanced equipment, skilled engineers, and strong international demand. Local suppliers invest heavily in production lines imported from Spain, Germany, Japan, and Taiwan. This modernization allows Vietnamese factories to meet global quality standards while keeping costs competitive.

• Common alloys: 6005, 6063, 6061.
• Heat treatments: T5, T6.
• Maximum length: up to 21 meters.
• Annual production capacity: 55,000 tons of construction and industrial aluminum, plus 60,000 tons of aluminum billets.

In addition, many factories operate integrated processing lines that include anodizing, PVDF painting, powder coating, and precision machining. As a result, global clients receive complete, ready-to-use aluminum extrusion products directly from Vietnam.
