Basics of Aluminum Extrusion Dies

Selecting the right type of aluminum extrusion die is essential to achieving the desired profile characteristics and ensuring efficiency of the extrusion process. Here are some general guidelines for selecting the appropriate type of aluminum extrusion die based on your project requirements:

1.Solid Profiles

For profiles that do not have any enclosed voids or openings, such as structural components, bars, and rods, solid dies are the most appropriate choice. Solid dies are designed to create solid profiles with uniform cross-sections and are commonly used in various industries that manufacture structural components.

2.Partially Enclosed Profiles

If the required profile has partially enclosed voids or openings, semi-hollow dies are the most appropriate choice. Semi-hollow dies are designed to produce profiles with partially enclosed voids, striking a balance between structural integrity and lighter weight. These are often used to manufacture profiles that require strength and lightness, such as window frames and railings.

3.Fully Enclosed Profiles

For profiles that have fully enclosed voids or openings, such as tubes and pipes, hollow dies are the most appropriate choice. Hollow dies are designed to create profiles with fully enclosed voids or openings and are commonly used to manufacture tubes, pipes, and other hollow structures.

4.Complex profiles

For profiles with complex shapes or multiple materials, a coextrusion die or a multi-opening die may be required. A coextrusion die can extrude two or more different aluminum alloys through the same die simultaneously, thus forming a single profile with different properties in different cross-sections. A multi-opening die has multiple openings and is used to produce multiple profiles simultaneously.
