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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for controlling the temperature of molds, dies, and injection barrels using fluid media","description":"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","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8501060","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
