Extrusion dies 

Extrusion dies can be made to form a virtually limitless array of shapes and sizes.
The die itself is a steel disk (normally H13) with an opening, the size and shape of the intended cross-section of the final extruded product, cut through it.

Dies are broadly grouped as solid (or flat) dies, which produce solid shapes, and hollow dies,which produce hollow or semihollow shapes.

Combinations of solid, semihollow, and/or hollow shapes may be incorporated into a single die.

SOLID DIE

A solid die may have one or more orifices or apertures through which the softened alloy is extruded.

Multiple apertures in a single die produce multiple extrusions with each stroke of the press.

Hollow Die

Hollow dies take a variety of forms: bridge, porthole, and spider dies, for example, include a fixed stub mandrel as an integral part of the die.

Each type of hollow extrusion die serves certain functions and carries its own advantages and disadvantages. The manufacturing methods and costs vary widely.

The choice of design, and even manufacturing methods, will depend on the profile, press and container size, and production requirements.

A semihollow die extrudes a shape that is nearly hollow, partially enclosing a void, the area of which  is large in comparison with the gap where the tongue is connected to the main body of the die.

Aluminum Profile Extrusion Die is a precision tool used in the aluminum extrusion process to produce aluminum profiles with various shapes, sizes, and specifications. It is designed to withstand high pressure, high temperature, and continuous production conditions while maintaining accurate profile dimensions and stable extrusion performance.

Made from high-quality die steel, aluminum profile extrusion dies are processed through advanced CNC machining, heat treatment, and surface finishing technologies. These manufacturing processes improve the die’s strength, wear resistance, and service life, helping manufacturers achieve efficient and consistent aluminum profile production.

The extrusion die design directly affects the quality, appearance, and dimensional accuracy of the final aluminum profiles. Professional manufacturers use advanced design software and precision manufacturing equipment to develop dies with optimized structures, smooth surfaces, and reliable performance. Proper die design can reduce material waste, improve extrusion efficiency, and ensure stable production results.

Aluminum Profile Extrusion Dies are widely used for producing profiles in construction, industrial equipment, transportation, electronics, solar energy systems, and other industries. They can be customized according to different aluminum alloys, profile designs, wall thickness requirements, and application purposes.

OEM and customized services are available to meet specific customer requirements, including die design, profile development support, material selection, and production solutions. Strict quality inspection is carried out throughout the manufacturing process to ensure accuracy, durability, and reliable operation.

With excellent precision, strong durability, and flexible customization options, Aluminum Profile Extrusion Die provides an essential solution for producing high-quality aluminum profiles for various industrial applications.
