What Are The Factors That Affect The Life of The Mold?

1.the geometry of the mold

The geometric shapes that affect the life of the injection mold are the radius of the die, the end face shape of the punch, the cone Angle of the die and the size of the change of the cross section of the die.

2.the working conditions of the mold

The material of the forming part and the temperature of the forming part are important factors affecting the life of the mold. The material of the forming part is different, the molding pressure required is not the same, and the force of the mold is not the same. The smaller the molding pressure, the smaller the mold force, the longer the service life of the mold; The forming temperature has an effect on the strength of the material, and also affects the contact surface between the mold and the forming part.

3.the accuracy and stiffness of the equipment

The higher the guiding accuracy of the slider movement, the higher the positioning accuracy of the front and rear die, the less likely it is to produce lateral load and torque, so that the die wear is uniform. The higher the die life. The stiffness of the equipment and the smaller the elastic deformation generated during molding, the front and back molds can be better matched.
