Abstract
An injection molding machine control device where mold element separation distance is measured and integrated as a function of time while moldable material is being introduced in the mold cavity between the mold elements. When the integral value reaches a preselected value, the mold injection pressure is changed and the moldable material is allowed to cure within the cavity.
