Generally speaking, the technological elements of aluminum extrusion die design mainly include the following contents:
(1) the shape and dimension of the outlet section of the die cavity;
(2) the shape and length of the hole working band;
(3) the rounded radius of the end of the die;
(4) thrust angle or angle of flow;
(5) the transition zone between the die angle and the surface of the extrusion barrel to the surface of the mold;
(6) the population angle of the hole work belt is called the obstruction angle;
(7) the shape, size and fillet radius of the transition region of the material pocket in the aluminum profile stage variable profile die;
(8) the arrangement of the cavity on the mold surface and the distribution of metal;
(9) the number of holes and their distribution;
(10) the thickness and size of the mold;
