Classification of aluminum extrusion dies?

(1) According to the section shape of the die hole compression zone, it can be divided into: flat die, conical die, flat cone die, streamlined die and double cone die, etc., as shown in Figure 1;

(2) According to the types of extruded aluminum profiles, it can be divided into bar molds, ordinary solid profile molds, wall panel molds, variable-section profile molds, pipe molds, and hollow profile molds;

(3) According to the number of die holes, it can be divided into single-hole die and multi-hole die;

(4) According to the extrusion method and process characteristics, it can be divided into hot extrusion die, cold extrusion die, hydro-static extrusion die, reverse extrusion die, continuous extrusion die, water cooling die, wide expansion die, horizontal extrusion Machine molds and vertical extrusion machine molds, etc.;

(5) According to the mold structure, it can be divided into integral mold, split mold, removable mold, movable mold, tongue-shaped combined mold, plane split combined mold, embedded mold, fork mold, front mold, protective mold, etc.;

Cylindrical-conical molds for cones, reinforced molds, etc.;

The above classification methods are relative, and often a mold has both the above several features in the classification. Moreover, factors such as the process characteristics of the body and the shape of the aluminum profile are subdivided into several subcategories. For example, the rod mold can be divided into round rod mold, square rod mold, hexagonal rod mold and special-shaped rod mold, etc.;
