In the aluminum profile manufacturing industry, the extrusion die is a critical component that determines the shape, quality, and precision of the extruded aluminum profiles. At Viet Y Aluminium Co., Ltd., the die design and machining process is conducted methodically and professionally, using modern machinery and a team of experienced engineers to ensure the highest product standards.

What is an Aluminum Extrusion Die?

An aluminum extrusion die is a heat-resistant steel tool designed with a specific cross-sectional shape. When hot aluminum billets are forced through the die under high pressure, they form aluminum profiles that exactly match the die’s design. Each die corresponds to a unique aluminum profile, used in various applications such as doors, curtain walls, braces, machine frames, furniture, and industrial structures.

Steps in Extrusion Die Manufacturing at Viet Y Aluminium

- Receiving Requirements and Technical Drawings

Customers provide technical drawings or real product samples. Viet Y Aluminium will assess the design’s functionality and suggest adjustments if needed to ensure extrudability and prolong die life.

- Die Design Using CAD/CAM Software

Engineers use CAD/CAM software to create precise 2D and 3D models of the die. The design ensures accuracy in shape, dimensions, strength distribution, and wall thickness of the aluminum profile.

- CNC Machining of the Die

Specialized die steel is processed using 3- to 5-axis CNC machines to precisely cut details such as channels, vents, and extrusion openings. Tolerances are tightly controlled to ensure long-lasting and stable die performance.

- Heat Treatment and Cooling

After machining, the die undergoes heat treatment to increase hardness, wear resistance, and thermal resistance. The cooling process is carefully managed to prevent cracking from thermal shock.

- Installation and Test Extrusion

The die is installed on the extrusion line and tested with real aluminum billets. The resulting aluminum profile is checked for shape, straightness, surface finish, and dimensions. The die is then fine-tuned if necessary.
