Integrated single and twin screw extruder
An extruder is disclosed, and more particularly, to an integrated single screw extruder and a twin screw extruder for mixing, compounding, kneading and/or extruding of materials. The integrated extruder includes a first barrel assembly and a second barrel assembly. The integrated extruder further includes a first screw having a first threaded portion and a second threaded portion. The first threaded portion is housed within the first barrel assembly and is configured to provide upstream material processing. The second threaded portion is housed within the second barrel assembly and is configured to provide downstream material processing. The integrated extruder further includes a second screw having a non-threaded shaft portion and a threaded portion. The threaded portion of the second screw is housed within the second barrel assembly and is configured to provide the downstream material processing with the second threaded portion of the first screw.
DIE MOUNTED CONTACT APPLICATOR
A slot die assembly for applying at least one material onto a substrate includes an adapter having a passive heat transfer device, a shim package fluidically connected to the adapter, the shim package having a first material discharge slot and a second material discharge slot, and a die plate having a one or more fluid channels fluidically connected to the shim package. The assembly also includes one or more mounting studs extending from the adapter, the mounting studs configured to engage a parent machine.
EXTRUSION FACILITY WITH UNDERGROUND TRANSFER OF THE TOOL MODULE
An extrusion facility comprises a core site (5) designed to receive a tool module (6) in order to connect an extruder (4) to it with a view to producing a profiled element (2), the core site (5) being located at a first level (11), referred to as working level (11), which is provided with a floor (12) on which an operator can move about to access the core site (5), and an underground-transfer device (30) which makes it possible to convey the tool module (6) to the core site (5) and, respectively, to remove the tool module (6) from the core site (5), from and to, respectively, a remote preparation site (40) by using a lift cage (31, 41) to move the tool module (6) through the floor (12) from, or respectively to, a second level (32), referred to as basement (32), which is located below the floor (12).
EXTRUSION MACHINE
Disclosed is an extrusion machine including a head body and a die seat arranged on a front surface of the head body. A die is attached in a removable manner to the die seat. The die includes an extrusion outlet that is in communication with an opening through which plastic material is discharged out of the head body. A holding member is in contact with a front surface of the die. A pressing mechanism presses the holding member against the front surface of the die.
Method and apparatus for handling a die unit for a sheet extrusion system
A method of, and apparatus for, handling a first die unit usable on a sheet extrusion system. The method includes the steps of: obtaining a carriage; placing the first die unit in a supported staging position on the carriage, the carriage configured so that with the first die unit in the supported staging position the first die unit can be moved guidingly around an axis; with the first die unit in the supported staging position, moving the first die unit guidingly around the axis to a desired angular orientation to thereby facilitate access to one or more identified regions of the first die unit; and performing an operation at the one or more identified regions of the first die unit.
Method for two-stage closure of a roller extrusion facility for precise adjustment of the air gap for generating a profiled element
A method for closing a facility (1) for extrusion of a profiled element (2) comprising a roller (3) supported by a bearing (4), a tool module (10) intended to interact with the roller (3) so as to form an air gap (12) for shaping the profiled element (2), and at least a first head module (13) having a first extruder (14) comprises an engagement step (s1), during which the tool module (10) is urged against the first bearing (4) by a preload force (F_Z), in an engagement direction (Z), then a clamping step (s2) during which the tool module (10) is clamped between the first head module (13) and a second head module (23), on either side of the tool module (10), and by subjecting them to a clamping force (F_X), in a coupling direction (X) which is transverse to the engagement direction (Z).
