Several aspects should be paid attention to during the whole heat treatment process of aluminum alloy profile extrusion die:

        A. The temperature raising rate should be fast in the high temperature section, and the heat insulation time should not be too long to prevent the extrusion mold from being overheated or too hot. Overheating - thick crystal, overheated - low dissolved point elements and miscellaneous factors cause melting;

        B, aluminum extrusion die after heat treatment should be immediately quenched to prevent cracks;

        C, extrusion die found hardness after heat treatment or inadequate strength uneven distribution, quenching, should he carried out according to the process again to carry out heat treatment (when the strength value laser cutting aluminum extrusion die die when working with electricity flow not easy too, in case of melting layer too thick, because of the melting layer is die work embrittlement with sexual fall off one of the primary factors, The gap between charge and discharge in production and processing is operated at 0.01mm; Wedm extrusion dies when work with empty tool, power flow is not easy too, in case of scald, production, processing and surface 5454 aluminum charge and discharge gap control in 0.05 ~ 0.1 mm, thick at the knife from the work with the most high level 1 mm off electric grinding, on the basis of die hole work overall width adjust electric level working face with bevel shape (the surface of a right, The surface roughness should be low), replace the positive and negative poles and carry out deep processing, which can ensure timely production and processing, and the vertical surface of the connecting knife is bright and flat, and reduce the surface mold line of the workpiece.
