Abstract
A molding machine for producing plastic hollow bodies and including at least one extrusion die, an injection plunger element for delivering plasticized plastic material to the at least one extrusion die, two blow mold halves arranged between the extrusion die and triggering device and displaceable toward each other for forming a blow mold in which the preform produced by the extrusion die is received and a hollow body is formed, a computerized control system for controlling parameters of the produced hollow bodies, a pressure-measuring device for determining pressure of the plasticized plastic material delivered to the injection die, weight and height measuring devices for determining weight and height of the produced hollow bodies, data-transmitting and control lines connecting the control system with the measuring devices, and a transfer gripping device for transferring hollow bodies from the blow mold station to the weight and height measuring devices.
