Small hot-runner nozzles with replaceable heaters are new from Synventive Molding Solutions, Peabody, Mass. The 04C and 06C nozzles replace Synventive’s 10-year-old CA nozzle. Besides replaceable heaters for quick, easy maintenance, the nozzles have new tip inserts designed for direct gating of polypropylene and for fast cycles. Synventive also introduced the MultiZone temperature controller with up to 192 zones. It is said to be compact and simple to operate. The 8- or 12-in. color touchscreen shows graphic displays of system performance. Diagnostics check the mold for heater, thermocouple, and wiring faults and can predict imminent heater failure.
