Straight Shot® Hot Sprue Bushings T-Series Straight Shot
84
The DME standard “T” Series Straight Shot improves the performance of three-plate molds by virtually eliminating the sprue from the runner system. It is available with 1 / 2 " spherical radius, and 240 volt heater and a 7 / 8 " or 1 3 / 8 " long stripper plate bushing to suit the application.

Typical Application
NOTE: The expansion factor must be taken into consideration prior to machining for and installation of the bushing. This factor (BE) must then be added to the A dimension. The formula for determining this expansion factor is as follows: BE = “A” dimension x 0.00000633 x nozzle set point - 68ºF (assuming the mold is at 68ºF during operation). If mold temperature is different, substitute 68ºF with actual mold temperature. EXAMPLE: Given a setpoint of 500°F: BE = 1.375 × .0000063 × (500 – 68) = .004 thus 1.375 + .004 = 1.379. Please note that the above information is given as an example. Variations may occur based on mold configuration and cooling factor. In some instances, it may be necessary to obtain an empirical factor.
