Abstract
The blowing-in of the sand into the mould is continued while the pressure in the mould chamber increases through a maximum mould pressure and the blowing-in is terminated at a predetermined time period subsequent to reaching maximum pressure. This method ensures that the mould chamber will be completely filled independently of its size or shape without having to keep the blowing-in mould sand active for a longer time than absolutely necessary.
