New D-Max single-drop hot sprue bushings from DME, Madison Heights, Mich., have two zones of heating with separate thermocouples. They have a square coil heater on the head of the nozzle and DME’s standard slip-on, cast-in heater on the nozzle body, which is said to give better control than square coils and last about 50% longer. D-Max nozzles use the same type of heater and tip as in a DME multi-drop system, so prototyping with a single cavity will mimic a production system effectively, DME says. D-Max nozzles come in three sizes with 0.250 to 0. 625 in. flow channels. They will be displayed at NPE 2012 in Orlando, Apr. 1-5, at booth 2803).
