Seal point

from Wikipedia, the free encyclopedia

The sealing point refers to the point in time during injection molding when the plasticized plastic ( thermoplastic ) has cooled down to the point where it has completely solidified at the gate . After solidification, it is no longer possible to fill further plastic into the cavity of the injection molding tool .
