Cooling greatly influences the solidification of melt in plastic molding, which affect potential deformation occurred during the mold ejection and occupy 70%-80% of the entire molding cycle time. A well-designed cooling system will shorten the molding time and enhance production; an improper one will cause warpage, non-uniform shrinkage, displacement, etc.

Moldex3D Cool, based on true 3D technology, is an efficient tool which can precisely analyze the mold temperature, the efficiency of cooling channel and estimate the cooling time. Moldex3D Cool provides the troubleshooting tools to detect possible mold cooling system defects, such as unbalanced cooling, hot spots, prolonged cooling time due to poor cooling efficiency. With Moldex3D true 3D technology, users can further optimize the cooling system design for better product quality and reduce cycle time.
