The life of a plastic mold is determined by multiple factors, including material selection, design quality, operating conditions, and maintenance. Generally speaking, the life of a plastic mold can be divided into design life and service life. The design life of an injection mold is generally about 10 years, and the service life of an injection mold is generally between tens of thousands and hundreds of thousands of injection cycles.

The following are the four main factors that affect the life of an injection mold:

 

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

 

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

 

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

 

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

 

It should be noted that the life of a plastic mold is a relative concept and is affected by a combination of multiple factors. Different molds may have a large difference in life under different conditions of use. Therefore, in actual applications, evaluation and management should be carried out according to specific circumstances, and the mold should be regularly inspected and maintained to ensure its normal operation and extend its service life.

 

At the same time, the continuous advancement of technology and the application of new materials have also provided more possibilities for improving the life of plastic molds. By optimizing the 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.
