Correct design of extruded 7075 aluminum mold

     The correct design, careful processing, reasonable mold repair and timely nitriding of the extruded 7075 aluminum mold are the key measures to prevent the defects of the structure.

a. The correct design of the extruded 7075 aluminum mold, reasonable layout of the split hole, reasonable determination of the length of the working belt, and the transition of the length change, the mold bridge dripping shape, reasonable welding angle, so that the welding point falls on the plane of the welding chamber In the case of ensuring the rigidity and strength of the core of the mold, deepening the depth of the welding chamber or expanding the sectional area of the welding chamber, and adopting the "sink bridge" when necessary, is a basic measure for preventing the stripe defects of the structure.

b. 7075 aluminum mold should be processed strictly according to the drawings, especially pay attention to improve the surface luminosity of the split hole and the mold bridge is dripping, improve the flow state of solid metal and reduce friction heat;

c. For the extrusion of the mold that produces the streaks, the mold repairer should go to the site to understand the mold discharge situation and determine the correct mold repair plan; the mold repairer personally observes the state of the material discharge moment than the observation material discharge material head. It is much better to determine the effectiveness of the repair program;

d. The extrusion die is nitrided in time to ensure a reasonable flow of solid metal.
