DME Co.'s D-Max line of single hot sprue bushings incorporate DME's standard slip-on, cast-in heaters on the nozzle body. The Madison Heights, Mich.-based company said that provides a more uniform heat profile than traditional square coil heaters.
DME will showcase the D-Max line at NPE 2012. The sprue bushings are ideal for prototyping and short-run production. The standardized bushings allow moldmakers to exactly simulate multi-drop systems using the same basic components, with no need for special heaters, tips, retainers or needles.
“Slip-on, cast-in heaters give molders better control of the heat in the nozzle body, so they can reduce stringing,” said Craig Kovacic, DME's hot runner manager. They also last about 50 percent longer than square coils, he said.
