Mould storage conditions for Injection Moulding
Injection molding is a widely used manufacturing process for producing plastic products of various shapes and sizes. In this process, the melted plastic material is injected into a mold cavity under high pressure and temperature, where it solidifies and takes the shape of the cavity. However, the molds used in injection molding require careful storage to maintain their quality and prevent damage. In this article, we will discuss the best temperatures to store molds when not being used for injection molding.
The temperature at which the molds are stored is a critical factor that determines their longevity and quality. Ideally, the molds should be stored in a temperature-controlled environment that is free from moisture, dust, and other contaminants. The temperature of the storage area should be maintained within a specific range to prevent the molds from warping, cracking, or developing other defects.
The optimal temperature range for storing molds is between 50°F and 70°F (10°C and 21°C). This temperature range is suitable for most types of molds used in injection molding and helps to prevent thermal cycling that can lead to mold damage. However, it is essential to note that the temperature range may vary depending on the type of mold material, size, and shape.
For example, molds made of aluminum or steel can be stored at a slightly higher temperature range of 70°F to 80°F (21°C to 27°C). These materials have higher thermal conductivity and can dissipate heat more efficiently, making them less susceptible to thermal cycling. On the other hand, molds made of plastic or composites should be stored at a lower temperature range of 50°F to 60°F (10°C to 16°C) to prevent deformation or warping.
In addition to temperature, it is also crucial to store the molds in a dry environment with low humidity levels. High humidity levels can cause moisture absorption, which can lead to corrosion, rusting, or mold growth on the mold surface. Therefore, it is recommended to store the molds in a controlled environment with relative humidity levels between 35% and 50%.
It is also essential to store the molds in an upright position to prevent any deformation or warping due to their weight. The molds should be placed on a level surface and covered with a protective layer to prevent dust, debris, or other contaminants from settling on the surface.
In conclusion, storing molds at the correct temperature is essential to maintain their quality and prevent damage when not being used for injection molding. The optimal temperature range for storing molds is between 50°F and 70°F (10°C and 21°C), depending on the type of mold material, size, and shape. Molds should also be stored in a dry environment with low humidity levels and in an upright position to prevent deformation or warping.
