PMC Optimized Thermal Management System (OTMS) Mold Temperature Control Effectiveness Electric Heat vs. Pressurized Water

PMC Smart Solutions

Many materials used for injection molding of medical applications require higher mold temperatures for proper processing than typical water based mold temperature controllers can deliver. Polyetheretherketone (PEEK), polyaryletherketone (PAEK), polysulfone (PSU) and polyphenylsulfone (PPSU) are some of these materials that require mold temperatures in excess of 220 degrees F. Heat transfer oils are typically used for mold temperature control in these high heat applications; however, due to the potential for product contamination, systems that use these oils have traditionally not been used in clean room processing. For this reason, electric cartridge heaters are commonly used to provide mold temperature control in clean room molding for materials requiring these high mold temperatures.
