A, high temperature section temperature rate should be fast, heat insulation time should not be too long, in order to prevent extrusion mold caused by coarse crystal or too hot, home decoration aluminum overheating - thick crystal, coarse crystal - low solution point element and miscellaneous caused by melting;

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

C, extrusion die found insufficient hardness after heat treatment process or strength uneven distribution, quenching, should he carried out according to processing technology to carry out the heat treatment process (again when the strength value laser cutting aluminum extrusion die die when work with too much power flow is not easy, in case of melting layer too thick, is due to the melting layer of die working embrittlement off one of the key factors, The gap between charge and discharge in production and processing is operated at 0.01mm; Wedm extrusion dies with empty knife work, the power flow is not easy too, in case of scald, production, processing and surface charge and discharge gap control in 0.05 ~ 0.1 mm, thick at the knife from the work of the most high level 1 mm off electric grinding, on the basis of die hole with overall width adjustment of electrical level of workbench face bevel shape (provisions of its surface, 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.

The cause of the hole caused by aluminum profile:

1) The workpiece of aluminum profile product is not cleaned completely after alkali washing. If the caustic soda solution entered into the hole during alkali washing cannot be cleaned neatly, the caustic soda solution will promote the outflow of the cylinder eye after air oxidation treatment, resulting in the erosion of the air oxide film around the hole

2) The holes around the aluminum profile products are active. When aluminum profile tapping screw hole hair acerbity, operators are still coated with active to moisten, alkali washing if the caustic soda solution is lack of demulsifier, active is not able to get rid of.

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