Performance Plastics – Factors that Determine Injection Mold ROIMay 25, 2023 | Blog, Engineering Capabilities Blogs
Injection molds are one of the most significant investments a manufacturer can make. The lifespan of the injection mold depends on several factors; the design and construction of the mold, the type of material being molded, the operating conditions, and the maintenance practices employed. Generally, high-quality molds are built to be durable and last for a significant period. Below are some factors that affect the longevity of injection molds:
- Operating Conditions – The conditions in which your injection mold operates have a corresponding effect on the lifespan of your mold. Will the mold be used in dirty or harsh environmental conditions? Or is it run in a clean, sanitary environment? Dirt can take a toll on your mold.
- Time between production runs – In general, the less time between runs the shorter the lifespan of your mold will be. The result of less time between runs is that molds may be less likely to get full mold maintenance between each cycle.
- Cycle times – Longer, slower cycle times can be less taxing on your molds, which in turn may help them last longer. The length of your cycle time is largely dependent on elements of your design, including wall thickness, as well as design complexity.
- Injection mold material – The materials used to create your mold will also play a role in its longevity. Aluminum molds, for instance, won’t last as long as their steel counterparts. The materials being molded also play a role in longevity, as some materials will be harder on molds than others.
It’s important to mention that the lifespan of an injection mold is not solely determined by the number of cycles but also by the overall condition and functionality of the mold. Factors such as wear, damage, and changes in the molding material or production requirements can necessitate repairs.
