Abstract
A toner extruder for the preparation of a toner resin extrudate from a resin is provided. The extruder includes a housing defining a housing aperture and a resin inlet opening in the housing. The extruder also includes a conveyor for conveying the resin through the housing aperture. The extruder further includes a member adjacent the resin inlet opening for inhibiting the heat transfer from the housing and/or the conveyor to the resin at the opening. The flow of resin adjacent the opening is thus improved.

A toner extruder for the preparation of a toner resin extrudate from a resin comprising:
- a housing defining a housing aperture and a resin inlet opening therein;
- means for conveying the resin through the housing aperture;
- and
- an insert disposed at least partially within the resin inlet opening for inhibiting the heat transfer from said housing to the resin at the opening, whereby the flow of resin adjacent the opening is improved.
A method for preparing a toner resin from a base resin, comprising:
- conveying the base resin to an aperture in the housing of a toner extruder, the housing surrounding a conveyor;
- positioning an insert at least partially within the aperture so as to inhibiting the heat transfer from the extruder to the base resin at the aperture
- adding chemical initiator to a toner extruder;
- mixing the base resin and the chemical initiator within the extruder to form the mixed resin;
- and
- conveying the mixed resin within the extruder to an extruding die.
