Abstract
When pouring casting cavities in casting moulds having after-feeding reservoirs, tubular lances are introduced, firstly with their point at a short distance from the after-feeding reservoir, after which the lances are pressurized from a pressure chamber and by means of a member with an inclined surface pressed downwardly through the last short distance to the after-feeding reservoir so as to pressurize the latter. With this arrangement it is possible to pressurize the after-feeding reservoirs without the need of equipping the casting moulds with complicated extra equipment and without risk of the molten metal being pressurized unnecessarily.
