When manufacturing silicone parts by injection molding, removing air from the mold before injecting the material is a crucial step to ensure optimal product quality.
This process, known as mold evacuation, is used to avoid air bubbles and inclusions in the final product,
which could otherwise negatively affect the mechanical properties and aesthetic appearance.
By removing air from the mold cavity, the viscous silicone material can be evenly distributed and fill all areas of the mold.
This leads to increased accuracy of the component geometry and improved surface quality.
The use of this process is particularly important in silicone processing, as it ensures product consistency and significantly reduces the likelihood of production errors.
