摘要： For controlling temperature in the molding of plastics, metal, ceramic, or die-casting, a circulator supporting a molding machine includes a fixed displacement pump driven by an electronic servo motor for volumetric metering of thermal fluid to or from the molding machine. A pre-set or dynamically controlled volume and flow rate profile matches the heating and cooling requirement of a molding machine and process. Volumetric metering may be based on parameters such as time, machine cycle status, temperature, pressure, and/or flow rate. Fluid may be circulated through the mold at positive or negative pressure at fixed, variable, or pulsed flow. The supply side in a fluid loop may be restricted so as to cause a pressure drop in or upstream of the mold, die or barrel, and seed bubbles may be injected into the fluid flow to excite vaporization and lowering of the fluid temperature.

摘要： In a method for thermally controlling a mold, initial measurements of flow versus pressure or pumping speed for a thermal exchange liquid are used to select an achievable flow within a maximum pressure. Subsequently, the system's identity and integrity are verified by repeating at least one measurement before and/or during a process run. An energy exchange rate can be adjusted to a moving average over preceding cycles. Thermal equilibrium can be detected by sensing changes in temperature to or from the process, or in energy exchange rates, from cycle to cycle. An energy exchange rate set point can be set to an initial value during startup, and then reset to an equilibrium value. Energy efficient operating conditions can be determined by comparing circulator energy consumption with thermal energy exchange rates over a range of flow rates and/or temperatures to the process. Cooling flow pulse timing can be graphically adjusted.

摘要： A method and apparatus are disclosed for managing thermal energy transfer between a mold, die or cavity and a thermal transfer fluid. The thermal energy being exchanged with the mold, die or cavity is calculated in real time as a function of the temperature differential between inlet and outlet fluid temperatures, the volumetric rate of fluid delivery, and known characteristics of the fluid. The rate of thermal energy exchange is controlled by varying the fluid delivery rate in accordance with a desired thermal energy exchange profile.
