Abstract
A sizer for cooling an extrudate, which includes a core and a housing. The core includes an extrusion channel which accommodates the extrudate, a core cooling channel, and a core vacuum channel in fluid communication with the extrusion channel. The housing includes a housing cooling channel and a housing vacuum channel. The core cooling channel is in fluid communication with the housing cooling channel, and the core vacuum channel is in fluid communication with the housing vacuum channel.
Claims45
A sizer for cooling an extrudate, comprising:
- a core comprising:
- an extrusion channel configured to accommodate the extrudate;
- a core cooling channel;
- and
- a core vacuum channel in fluid communication with the extrusion channel;
- wherein the core is comprised of a metal;
- and
- a housing for housing the core, comprising:
- a housing cooling channel in fluid communication with the core cooling channel;
- and
- a housing vacuum channel in fluid communication with the core vacuum channel;
- wherein the housing is comprised of a polymer;
- wherein the housing cooling channel and the core cooling channel form a cooling pathway adapted to circulate a coolant through the sizer;
- and
- wherein the housing vacuum channel and the core vacuum channel form a vacuum pathway adapted to transmit suction forces to the extrudate.
A method for creating a sizer adapted to cool an extrudate, comprising the steps of:
- creating, from a metal, a core comprising an upper core portion and a lower core portion, each of the upper core portion and the lower core portion comprising:
- an extrusion channel configured to accommodate the extrudate;
- a core cooling channel;
- and
- a core vacuum channel in fluid communication with the extrusion channel;
- creating, from a polymer, a housing for housing the core, comprising an upper housing portion and a lower housing portion, each of the upper housing portion and the lower housing portion comprising:
- a housing cooling channel;
- and
- a housing vacuum channel;
- and
- joining the upper housing portion to the upper core portion, the upper core portion to the lower core portion, and the lower core portion to the lower housing portion, to form:
- a continuous cooling pathway for the circulation of a coolant through the sizer, comprising the housing cooling channel and the core cooling channel;
- and
- a continuous vacuum pathway for the suction of the extrudate, comprising the housing vacuum channel and the core vacuum channel;
- wherein the upper core portion and the lower core portion are separately formed;
- and
- wherein the upper housing portion and the lower housing portion are separately formed.
A sizer for cooling an extrudate, comprising:
- a core comprising an upper core half and a lower core half, each of the upper core half and the lower core half comprising:
- an extrusion channel configured to accommodate the extrudate;
- a core cooling channel having at least one curved segment;
- and
- a core vacuum channel in fluid communication with the extrusion channel and having at least one curved segment;
- wherein the core is comprised of a metal;
- and
- a housing for housing the core, comprising an upper housing half and a lower housing half, each of the upper housing half and the lower housing half comprising:
- a housing cooling channel in fluid communication with the core cooling channel and having at least one curved segment;
- and
- a housing vacuum channel in fluid communication with the core vacuum channel and having at least one curved segment;
- wherein the housing is comprised of a polymer;
- wherein the housing cooling channel and the core cooling channel form a cooling pathway adapted to circulate a coolant through the sizer;
- and
- wherein the housing vacuum channel and the core vacuum channel form a vacuum pathway adapted to transmit suction forces to the extrudate.
