Aluminum profile extrusion die plays an important role in aluminum profile extrusion process, which is a basic tool to ensure product forming and make it have correct shape, size and accuracy.

In the process of using aluminum profile extrusion die, in order to make better use of extrusion die, we can use the appearance of aluminum die extrusion die, but we must check the correlation, otherwise it will affect the performance use of aluminum profile extrusion die, in the process of its use, we can pay attention to six kinds of inspection points of aluminum profile extrusion die.

1, the outer surface of the aluminum profile extrusion die should be the finishing surface after heat treatment;

2, the guide hole and welding chamber of the extrusion die should be smooth, without obvious convex and concave unequal defects, and must be at the corner of the die;

3, the die processing is smooth, smooth transition, no sharp angle or uneven;

4, split hole, split bridge machining level;

5, die core hollow knife and die hole hollow knife machining leveling;

6, the positioning pin and fastening bolt are installed completely.

The extrusion die design of the aluminum profile is different from the general mechanical juice. It is a technological design between mechanical design and pressure processing. in addition to that principle to be follow in reference to the mechanical design of the ship, it is also necessary to consider various process factors in the hot extrusion condition, which is determined by various factors, including the cause of the extrusion die design of the aluminum profile, The factors to be taken into account in the mold manufacturer and the factors to be taken into account in the extrusion of the producer.

From the aluminum profile extrusion die designer point of view. The structure of the extruder is the primary consideration. Which type of extruder is used to produce the juicy die, whether the profile can be extruded on the extruder, whether the extruder can extrude the required extrusion length, whether the required shape, size and position tolerances of the product can meet the requirements, the material, structure and shape size of the chess piece, the number of die holes, the size of the die hole, the tongue shape ratio and the extrusion ratio, as well as the various stresses during extrusion, Strain and so on, that is the designer to consider the problem.

From the perspective of the mold manufacturer, the size and processing of the die: the precision, the machining accuracy of the working belt and the surface roughness are the primary consideration. These requirements can be achieved so that the quality of the mold will be directly affected, that is, the quality of the produced product will be directly affected. There is also a problem of the strength of the mold, that is, the heat treatment at the time of processing, the surface diagnosis, the decarburization, and the change in surface hardness.

From the point of view of extrusion producer, the assembly and support of industrial aluminum profile die, the heating temperature of casting pad, die and extrusion simplicity, extrusion speed and process lubrication, control and adjustment of press, etc., are the problems to be considered by extrusion producer.
