            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:   Replacement Parts
             BE = “A” dimension x 0.00000633 x nozzle set
             point - 68ºF (assuming the mold is at 68ºF during   SUB-ASSEMBLY   BODY   HEATER TYPE   THERMOCOUPLE   NOZZLE BODY
             operation). If mold temperature is different,   REFERENCE  TYPE  (240 VAC, 250 WATT)  (36" LEADS)  ONLY
             substitute 68ºF with actual mold temperature.

            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.
