Cyclic heating of molds for container forming processes

Parent Category: Features

If you want to make a thermal analysis by using simulation then our meshless CFD simulation software NOGRID points is a great choice. Based on the geometrical model which can either be imported from your CAD or created with our CAD pre-processor Compass you can generate a computer model of a specific geometry in a very short time (compared to mesh-based methods) and see its thermal characteristics in advance.

NOGRID points shows how the heat is transferred either by heat conduction, heat radiation or by convection means by the flow of a fluid. You can couple also all kinds of heat transfer mechanisms. In the example below you can see an animation of the temperature distribution while the mold is heating up by cyclic loading of a glass gob. This model gives you a better understanding of the temperature distribution inside the mold depending on all process parameters within the glass container forming process. This helps to improve your design regarding efficiency and costs.

NOGRID points can perfectly be used for designing of container forming molds. The thermal homogenizing and the cooling/heating rate can be predicted. NOGRID points helps to understand the process by visualization the temperatures and the heat fluxes inside the molds. You can receive integral quantities which you can use to analyze the heat transport efficiency (see Figure 2).

What is CFD from NOGRID?

CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID simulation software you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
