In this video I do some lost foam casting experiments pouring aluminium.

I share some of the lessons learned. Here we test three different methods for improving surface finishes on aluminum lost foam castings. Transforming complex polystyrene models into solid aluminium , using the evaporative foam casting process.

When the molten metal is poured into the moul the heat vaporises the polystyrene. The casting process is complete when the molten aluminium has completely displaced the EPS and solidified. One difference between full-mould and lost foam processes is in the type of moulding sand used: in full-mould casting a binder . The lost foam casting process, also known as evaporative casting, is a low cost technique for manufacturing intricate, complex thin-walled casting iron and aluminium castings. Das Lost – Foam -Gießverfahren, eine Art des Vollform-Gießverfahrens, ist ein kostengünstiges Verfahren zur Herstellung komplexer .

One example is lost foam aluminium casting for series production with which we have been able to achieve technological leadership in Germany and in Europe. Kontext von „ lost foam “ in Englisch-Deutsch von Reverso Context: Process for the lost foam casting of metal pieces under controlled pressure. In the lost – foam casting process, liquid metal is poured directly onto a refractory- coate foamed polymer pattern which is buried in loose sand. The polymer pattern undergoes thermal degradation and.

The secret of lost foam casting is a continuous pour. No matter whether fire and smoke comes out (which it will) you must keep pouring. It seems the hydrostatic pressure of the incoming aluminium is sufficient to prevent the sand from caving in. Every time if the pour has been interrupted the have .
