1. Introduction



Injection molds are crucial tools in the injection molding process, and their lifespan directly impacts production efficiency and costs. The longevity of injection molds is a complex issue, influenced by numerous factors. This article delves into the lifespan of injection molds, explores the factors that affect their durability, and shares expert knowledge and recommendations to prolong mold life. Our aim is to enhance your understanding and management of mold service life.






2. Lifespan of Injection Molds



The lifespan of injection molds refers to the duration during which they can maintain normal operation and production. Typically, the lifespan of injection molds can be categorized into the following stages:



Initial Use Stage: Immediately after being put into use, the mold experiences a relatively short lifespan during its initial phase. This stage serves primarily to acclimate the mold to its working environment and process parameters, eliminating defects and adjusting mold performance.



Normal Operation Stage: This is the stage where the mold is utilized in regular production. During this phase, the mold's lifespan can vary significantly based on factors such as mold material, mold design, and maintenance practices.





Aging Stage: As the mold's usage accumulates, it gradually undergoes aging and wear. In this stage, the mold's performance and precision may decline, necessitating maintenance and potential repairs to sustain optimal operation.






3. Factors Affecting Mold Lifespan



Mold Material: The choice of mold material has a direct impact on mold lifespan. Commonly used mold materials include tool steel, stainless steel, and aluminum alloys. High-quality mold materials, featuring high hardness, wear resistance, and corrosion resistance, can significantly extend mold life.




Injection Molding Material: The selection and usage of injection molding materials also affect mold lifespan. Some specialized materials may be corrosive or high-temperature resistant, causing damage to the mold. Additionally, the composition and application method of the injection molding material can influence mold wear and damage.







Injection Molding Process: The selection and control of injection molding process parameters play a crucial role in mold lifespan. Optimal process parameters can minimize mold stress and wear, reducing fatigue and deformation.






Mold Design: Mold design significantly influences mold lifespan. During design, it's essential to consider the material properties, dimensional accuracy, and surface quality requirements of the product, avoiding over-design. A well-designed mold can reduce stress concentration and wear, enhancing mold rigidity and stability, thereby extending its lifespan.





Maintenance and Care: The maintenance and care of molds are directly related to prolonging their lifespan. Regular cleaning, lubrication, and rust prevention can minimize mold wear and damage. Furthermore, promptly repairing and replacing worn-out parts are key to maintaining mold performance and lifespan.








Operating Environment: The operating environment of the mold also affects its lifespan. Factors such as temperature, humidity, and vibration can impact mold stability and lifespan.






4. Measures to extend the life of molds



Reasonable mold design: During the mold design stage, appropriate materials and structures should be selected based on product requirements and production conditions to improve the rigidity and stability of the mold.



High-quality mold materials: Select high-quality mold materials with good wear resistance and corrosion resistance, capable of withstanding high-pressure and high-temperature working environments. Such as: S136, 718, NAK80, etc



Precise mold processing: Using advanced CNC processing equipment and techniques, we control the quality and precision of the process, reducing processing errors and deformation.



Optimization of injection molding process: By adjusting the injection molding process parameters, reduce the stress and wear of the mold, and improve the service life of the mold.



Regular maintenance and care: Clean, lubricate and rust-proof the mold regularly, repair and replace worn parts in time to extend the service life of the mold.



Proper use and operation: Use injection molding equipment and molds correctly, avoid excessive use and improper operation, and reduce mold damage and wear.
