Straight Shot® Hot Sprue Bushings

High-Performance Series Straight Shot ®
High-Performance Straight Shot® bushings are available as S-type
“S” Type (Standard Tip Configuration) • .062 or .125 DIA. Tips with .08 Land area • Seven shoulder lengths from 7 ⁄ 8 to 3 7 ⁄ 8
• .500 And .750 Spherical radius for machine nozzle • Replaces conventional cold sprue bushings to reduce cycle time and save material costs • Efficiently processes commodity grade resins • Provides low vestige gate cosmetics (.062 or .125 Gate diameters available)
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:
• High-watt density heater with distributed wattage to help prevent tip freeze-offs
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.
