Two new developments from Single Temperature Controls, Inc., Charlotte, N.C., broaden the capabilities of hot-water mold-temperature control. The company now offers pressurized hot-water systems for temperatures up to 225 C/437 F, suitable for molding PEEK and other high-temperature resins. The compact unit has a heating capacity of 6 kw and flow rate up to 30 l/min. Flow metering is standard.
Also new is a 1-kw Micro system for injection molds using micro-runners of 1- to 3-mm diam. A frequency-controlled, high-speed pump with solenoid coupling and low power consumption provides water at up to 150 C/320 F, 8 bar pressure (116 psi), and 1 to 2 l/min.
