Abstract
A method of regulating the hardening or setting time of a plastic mass in a mold of an injection molding machine, wherein during a relative movement between two mold halves in the presence of the pressure of the plastic mass the hardening time of the mass is regulated in the mold cavity as a function of the recuperation or recovery of such relative movement.
