D-M-E developed Straight-Shot Hot Sprue Bushings to eliminate sprues, permit larger shots and faster fills, and greatly extend heater life. The bushings feature an unrestricted “straightshot” channel to feed the part or runner.Material in the channel is heated by a special helical tubular heater which surrounds the melt stream. This heater distributes heat uniformly throughout the bushing and is virtually impervious to moisture, gases and
plastics contamination. The helical tubular heater (120 or 240 volt) is
thermocouple equipped so temperature can be closely controlled using a D-M-E single-zone Closed Loop Temperature Controller. The Standard S-Series Straight-Shot is designed for direct part gating or for feeding half-round or trapezoidal runners. It is supplied with a .16 diameter gate and no gate land. Available in seven standard shoulder lengths with either a 1⁄2" or 3⁄4" spherical radius and 120 or 240 volt heater. The S-Series Straight-Shot can be retrofitted to almost any mold that uses a conventional sprue bushing.
