Claims
- 1. A method for preparing a toner resin from a base resin, comprising:
conveying a base resin to an aperture in a housing of a toner extruder, the housing surrounding a conveyor; providing a lead-in gap at a feed port end of the conveyor; inhibiting adhesion of melted resin to walls of 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.
- 2. The method of claim 1 wherein inhibiting adhesion includes repelling melted base resin into a flow of base resin.
- 3. The method of claim 1 wherein inhibiting adhesion includes inhibiting heat transfer from the extruder to the base resin at the aperture.
- 4. The method of claim 3 wherein inhibiting the heat transfer further comprises spacing at least one of the housing and the conveyor from the resin at the aperture.
- 5. The method of claim 1 further comprising premixing the base resin with the chemical initiator.
- 6. The method of claim 1 further comprising cooling the base resin.
- 7. A toner resin preparation method comprising:
providing a base resin; providing a toner extruder comprising a housing and a conveyor in the housing; placing base resin in the toner extruder; conveying base resin to an aperture in the toner extruder housing; providing a lead-in gap at a feed port end of the conveyor; inhibiting adhesion of melted resin to walls of the aperture; adding chemical initiator to the base resin in the toner extruder; mixing the base resin and the chemical initiator within the extruder to form a mixed resin; conveying the mixed resin within the extruder to an extruding die; and extruding the mixed resin through the extruding die to form toner resin.
- 8. The method of claim 7 wherein inhibiting adhesion includes repelling melted base resin into a flow of base resin.
- 9. The method of claim 7 wherein inhibiting adhesion includes inhibiting heat transfer from the extruder to the base resin at the aperture.
- 10. The method of claim 9 wherein inhibiting the heat transfer further comprises spacing at least one of the housing and the conveyor from the resin at the aperture.
- 11. The method of claim 7 further comprising premixing the base resin with the chemical initiator.
- 12. The method of claim 7 further comprising cooling the base resin.
- 13. In a toner extruder comprising a housing and a conveyor, the housing comprising an aperture and a lead-in gap at a feed port end of the conveyor, the aperture having at least one wall, a toner resin preparation method comprising:
providing a base resin; placing base resin in the toner extruder; conveying base resin to the aperture in the toner extruder housing; inhibiting adhesion of melted resin to the at least one wall of the aperture; adding chemical initiator to the base resin in the toner extruder; mixing the base resin and the chemical initiator within the extruder to form a mixed resin; conveying the mixed resin within the extruder to an extruding die; and extruding the mixed resin through the extruding die to form toner resin.
- 14. The method of claim 13 wherein inhibiting adhesion includes repelling melted base resin into a flow of base resin.
- 15. The method of claim 13 wherein inhibiting adhesion includes inhibiting heat transfer from the extruder to the base resin at the aperture.
- 16. The method of claim 15 wherein inhibiting the heat transfer further comprises spacing at least one of the housing and the conveyor from the resin at the aperture.
- 17. The method of claim 13 further comprising premixing the base resin with the chemical initiator.
- 18. The method of claim 13 further comprising cooling the base resin.
