Running a small polyolefin pipe extruder
with a high-speed "hyper drive" doubles output without any extra gear wear, says Cincinnati Extrusion, Erlanger, Ky.
The gear-pump extruder
, highlighted in the literature, is a continuous process.
Options: Oriented discharge and trim, broad range of extruder
Session 2 on pump equipment will discuss the screw extruder
, ram (preform) extruders
, auxiliary devices, drives and transmissions, and temperature control.
CTE's technology has one short and one long screw side by side, changing from a twin-screw kneader to a single-screw extruder
Many extrusion process engineers never get the opportunity to design an extruder
screw, given that prices for custom-made replacements can rival the cost of a new SUV.
Double-sigma blade mixer in carbon steel available with extruder
Use proprietary grinding and drying technology and a conical single-screw extruder
connected to a polycondensation reactor, which upgrades PET's I.V.
A dual-purpose twin screw extruder
system has been introduced for use in wide ranging color and related dispersive mixing applications.
Macchi's syn-torque line had one 7000-Nm Siemens motor and Knoedel/SKF thrust bearing on the 80-mm main extruder
, two 5000-Nm torque motors on each of two 65-mm coextruders, and 200-Nm syn-torque motors driving nip and chill rolls, where they reportedly provide more precise tension control than do servo motors.
This manufacturer of thermoplastic extruders
has introduced a line of single screw extruders
designed for compatibility with screws from other extruder
Fillers are added where the cutter/compactor precuts, prewarms, and mixes material before it enters the extruder
. The result is said to be less expensive pelletized material for film with higher properties.
