Abstract
When compacting mold sand in a mold chamber (not shown) to form a mold or mold part (not shown) by using two co-operating squeeze plates with associated patterns (not shown), in which one squeeze plate is actuated before the other one, the second squeeze plate is not acuated until the pressure in the mold chamber (or a parameter depending on or derived from this pressure) has reached a predetermined value. By proceeding in this manner it is possible to manufacture molds or mold parts in series with practically the same hardness or solidity.
