APPARATUS FOR PRECISION VOLUMETRIC CONTROL OF A MOLDABLE MATERIAL IN AN INJECTION MOLDING PROCESS ABSTRACT OF THE DISCLOSURE A molding machine having a pair of separable mold elements forming a mold cavity therebetween is arranged for separation along a part-line. Means is provided for controlling the molded product which comprises means for measuring the separation of the mold elements resulting from the introduction of the moldable material into the mold cavity. Means is provided for detecting a predetermined separation of the mold elements, and means is provided for changing the pressure from the first pressure to the second pressure in response to the detection. The separation measuring means is arranged to measure the separation of the mold elements following changing the pressure. Means is provided for sensing when the separation of the mold elements stops increasing and for determining whether the cessation occurs within a predetermined cessation window. Means is provided to generate a signal of the cessation is not within the window to indicate that the cycle has exceeded the product limit. If the cessation is within the window, the second pressure is maintained until the material has cured.
