Porthole Die Stress checking.This is a quick and simple method used to check if a given die design has sufficientstrength and the likelihood of failure of the die during the die’s life time. This system isbased on the calculation that is used by the Die-maker and has been adjusted to a tableform. Th

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
