The instant invention broadly relates to a process and apparatus for filling a cavity with a reactive mixture. More particularly, the invention relates to a process for filling cavities, particularly mold cavities, with a reactive, flowable mixture which preferably forms foam, wherein at least two reaction components are brought into a mixing zone, where they are mixed and then brought into the cavity, the improvement wherein at the beginning of the filling process, during a limited time interval, the reaction mixture is fed into the cavity under low flow velocity until the mixture has reached a certain level in the cavity, and subsequently the remaining mixture to be injected, is fed in under increased flow velocity.

In a process for filling a mold with a reactive, flowable mixture which preferably forms foam, wherein at least two reaction components are brought into a mixing means, where said components are mixed and subsequently brought into a cavity of a mold, the improvement wherein, at the beginning of the filling process, a first portion of the reaction mixture is fed into the cavity of said mold under low flow velocity until the mixture has reached a preselected level in the cavity of said mold, less than full, and subsequently the remaining portion of the mixture to be injected is fed in under increased flow velocity.
