Abstract

In a low-pressure casting process using two-stage pressure control, the novelty is that, in the low pressure mould filling stage, the vol. flow of the gas is kept constant by pressure-controlled flow regulation when the back pressure increases during the filling of the mould and the solidification of the casting.
