If you're looking to perform a thermal analysis for the cyclic heating of molds for container forming processes, our meshless CFD software NOGRID points is an excellent solution. It delivers detailed insights into the thermal behavior of molds under cyclic heating conditions, allowing engineers to optimize mold design and improve product quality.
Using a geometrical model - either imported from your CAD system or created with our CAD preprocessor COMPASS - you can quickly generate a computer model of a specific geometry. Compared to traditional mesh-based methods, this process is significantly faster and allows you to analyze the thermal characteristics of the design in advance.
Periodic heat loads or cyclic heating of molds are very common in many industrial processes. Beginning with a cold, solid mold, the temperature gradually rises over time with each cycle until a steady-state temperature distribution is reached within the mold. At that stage only the temperature at boundaries where the heat load is applied will change with the given period.
Simulation of cyclic mold heating with NOGRID points
NOGRID points can compute and display how the heat is transferred either through heat conduction, heat radiation or by convection via fluid flow. These heat transfer mechanisms can also be fully coupled within a single simulation. In the example on the left, you can see an animation of the temperature distribution as the mold heats up through cyclic loading of a glass gob. This model provides a better understanding of the temperature distribution inside the mold, depending on all relevant process parameters in the glass container forming process. This helps to improve your design regarding efficiency and costs.
NOGRID points is ideally suited for the design of container forming molds. It enables precise prediction of thermal homogenizing as well as heating and cooling rates. By visualizing temperature distributions and heat fluxes within the molds, NOGRID points provides valuable insights into the process. Additionally, it delivers integral quantities that can be used to analyze heat transport efficiency.
