Low Pressure Die Casting Workspace

Low Pressure Die Casting Workspace Highlights

    • Pressure controlled filling for absolute fill accuracy
    • Full process modeling includes void, venting and back-pressure effects
    • Advanced solidification and heat transfer control for precise early freezing and solidification defects like porosity

Workspace Overview

The Low Pressure Die Casting Workspace is an intuitive modeling environment designed for engineers to successfully model low pressure die casting applications with FLOW-3D CAST. Flexible pressure controls allow engineers to accurately reproduce pressure, venting and backpressure conditions in order to deliver a complete analysis of fill, air entrapment and porosity defects. Die thermal management and state-of-the-art solidification models seamlessly connect to the fill through the workspace’s sub-process architecture. The Low Pressure Die Casting Workspace provides a complete and accurate solution for all aspects of the simulation in a simple yet versatile modeling environment.


This FLOW-3D CAST low pressure die casting simulation shows a thermal die cycling of an aluminum wheel die. This type of simulation is used to analyze the thermal saturation in the sliding and closing of the dies.
