The expansion factor must be taken into consideration prior
to machining for and installation of the bushing. This factor cycle time and save material costs
(BE) must then be added to the A dimension. The formula for
determining this expansion factor is as follows: • Efficiently processes commodity or engineering grade
BE = “A” dimension x 0.00000633 x nozzle set point - 68ºF
(assuming the mold is at 68ºF during operation). If mold resins
temperature is different, substitute 68ºF with actual mold
temperature. • Provides low vestige gate cosmetics (.062 or .125 Gate

EXAMPLE: diameters available)
Given a setpoint of 500°F:
BE = 1.375 × .0000063 × (500 – 68) = .004 thus 1.375 + .004 = 1.379. • High-watt density heater with distributed wattage 5.28 5.00
Please note that the above information is given as an example. (E-TYPE) (S-TYPE)
Variations may occur based on mold configuration and cooling to help prevent tip freeze-offs
