Die life is related to die type and structure, it is a certain period of die material performance, die design and manufacturing level.The comprehensive reflection of die heat treatment level and use and maintenance level.To a certain extent, die life reflects the level of metallurgical industry and

Introduction to Heat TreatmentThe aluminum extrusion dies use hot steel as the base material. It needs to go through the heat treatment procedure to improve the hardness and toughness to meet the extrusion conditions of high temperature and high pressure.Generally, during heat treatment, in order to

Some problems about hollow dies and die corrections 1.Twisting and side bending of square and round tube diesThe causes of torsion and side bending defects of aluminum extrusion profiles are mainly caused by uneven flow velocity caused by uneven metal supply.The picture below is a schematic diagram
