A set of high-quality injection molds, the service life is an important factor to judge it, but any object has a certain service life, injection molds are no exception, the service life of injection molds is affected by many factors, only if it is completely Understanding, can produce molds that last longer. The factors that affect the life of injection molds are as follows:

1. The geometry of the mold

The geometric shapes that affect the life of the injection mold include the fillet radius of the mold, the shape of the end face of the punch, the cone angle of the die, and the size of the change in the die section.

2. Working conditions of the mold

The material of the molded part and the temperature during molding are important factors that affect the life of the mold. The material of the molded part is different, the required molding pressure is also different, and the force of the mold is also different. The smaller the molding pressure, the smaller the force on the mold and the longer the service life of the mold; the molding temperature has an impact on the strength of the material, and also affects the contact surface between the mold and the molded part.

3. Precision and rigidity of equipment
The higher the guiding accuracy of the slider movement, the higher the positioning accuracy of the front and rear molds, the less likely it is to generate lateral loads and torques, and to make the mold wear evenly. The longer the mold life is. The rigidity of the equipment, the smaller the elastic deformation generated during molding, the better the front and rear molds can cooperate.

Only by understanding these factors that affect the life of the mold can we achieve a more refined effect in daily manufacturing and produce molds with longer service life.
