Press forming of aluminum foam during foaming using pin screen mold

Guar Foaming Albumin – A Foam Stabilizer

Expansion Mechanism in Foaming Aluminum Melts

The expansion of molten aluminum foam was studied to determine flow mechanisms in the cellular melt. The structure of the foaming melt evolved through a series of deformation stages before the foam stabilized and solidified. Changes in cell geometry during foam expansion were observed at different positions within the mold cavity and analyzed to determine flow mechanisms. The deformation patter...

Simulation of Foaming and Deformation for Composite Aluminum Foams

In this study, at the first stage, the rupture criterion of bubbles wall in Aluminum metal foam liquid was investigated by using Lattice Boltzmann. The two phases modeling were accomplished by using a modified Shan-Chen model. This model was run for several bubbles in A356+3wt.%SiC melt system. Then, bubbles morphologies (virtual metallographic) for A356+3wt.%SiC foams were simulated. Results s...

Screen Space Foam Rendering

We propose an approach to simulating and rendering physically based fluid effects in a VFX production environment using a client/server architecture that is practical for distributed simulation resources and that can be seamlessly integrated into commercial 3D animation packages. The fluid simulation implements smoothed particle hydrodynamics (SPH). We extend the concept of surface particles by...

Characterization and Control of Pin Diameter during In-Mold Assembly of Mesoscale Revolute Joints

Macro-scale revolute joints can be formed by first molding the hole and then molding the pin inside the hole. As the pin shrinks during the solidification process, it moves away from the hole and provides the clearance for the joint to function. The value of clearance in the macroscale joint can be controlled by carefully selecting the process parameters and the material for the pin. However, i...
