How long is the life of plastic mold?
The life of plastic molds is determined by a number of factors, including material selection, design quality, conditions of use and maintenance. Generally speaking, the life of plastic molds can be divided into design life and service life, injection mold design life is generally about 10 years, injection mold service life is generally between tens of thousands to hundreds of thousands of injection cycles.

Here are the four main factors that affect the life of injection molds:

(1) Material selection: The choice of mold material has an important impact on life. Common mold materials are tool steel, stainless steel and so on. High-quality mold materials with high hardness, wear resistance and corrosion resistance provide a longer service life.

(2) Design quality: The design quality of the mold directly affects its life. Reasonable mold design can reduce the stress concentration and fatigue crack, and improve the strength and stability of the mold. At the same time, taking into account the dimensional accuracy and surface quality requirements of the product, avoiding excessive design is also the key to extending the life of the mold.

(3) Conditions of use: The conditions of use of the mold will also affect the life. Factors such as temperature, pressure and number of cycles during injection molding will cause certain damage to the mold. Proper control of injection molding parameters, avoiding excessive temperature and pressure, as well as frequent cycles, can extend the service life of the mold.

(4) Maintenance: Regular maintenance is essential to extend the life of the mold. Including cleaning mold surface, lubricating mold parts, repairing damaged and worn parts, etc. In addition, timely treatment of adhesion and corrosion on the surface of the mold is also an important measure to maintain the performance and life of the mold.

It should be noted that the life of plastic molds is a relative concept and is affected by a combination of factors. Different molds in different conditions of use, its life may have a large difference. Therefore, in practical applications, it is assessed and managed according to the specific situation, and the mold is regularly checked and maintained to ensure its normal operation and extend its service life.

At the same time, the continuous progress of technology and the application of new materials also provide more possibilities for improving the life of plastic molds. By optimizing design, improving materials and processing technology, the service life of plastic molds can be further extended, and production efficiency and product quality can be improved.
