Lost Foam Casting Workspace

Lost Foam Casting Workspace Highlights

    • State-of-the art foam residue tracking
    • Advanced foam vaporization and metal front turbulence modeling
    • Solidification, porosity and surface defect analysis

Workspace Overview

The Lost Foam Casting Workspace provides lost foam casters with all the tools needed to simulate the filling, solidification and cooling subprocesses. Each subprocess is based on a template design which is tailored to provide a clean, easy-to-use setup interface that speaks the language of the casting process engineer. Since most defects in lost foam castings can be traced back to the filling profile, FLOW-3D CAST’s extraordinary accuracy in simulating metal flow and foam burning provides invaluable insights for producing high quality lost foam castings. Filling defects such as foam residue formation are accurately tracked and located in the final casting.

Description

This simulation is used to identify cold shuts that can develop due to foam residue accumulation near the end of the fill. FLOW-3D CAST‘s lost foam workspace can effectively simulate casting patterns with complex geometries, variable pattern foam densities, and adhesives. Foam residue and wicking behavior can be tracked to inform sound casting design based on accurate defect prediction. Quickly and easily output comparative design cases for expedited design cycles.
