Melt preparation<br />
Extrusion equipment<br />
<strong>Oerlikon</strong> <strong>Barmag</strong> spinning extruders excel at gentle and homogeneous<br />
melt <strong>production</strong> and are noted <strong>for</strong> cost effectiveness,<br />
reliability, and long service life.<br />
The utilization of top-quality, low wear materials – in particular<br />
<strong>for</strong> the extruder cylinders and the extruder screw – ensure<br />
long-term, error-free operation. The screw geometries with<br />
special homogenizing components have been engineered<br />
to ensure short dwell times in order to keep the thermal and<br />
mechanical loads of the melt to a minimum – the basis <strong>for</strong><br />
excellent melt and hence first-class yarn quality.<br />
<strong>Oerlikon</strong> <strong>Barmag</strong> extruders fulfill the e-save energy saving<br />
requirements. The e-save label is awarded to systems and<br />
components that have energy consumptions significantly<br />
lower than standard equivalent systems and components<br />
available on the market.<br />
<strong>Oerlikon</strong> <strong>Barmag</strong> extruders are characterized by their excellent<br />
barrel insulation resulting in energy savings and a low<br />
surface temperature on the barrel jacket. The two-step spur<br />
gear guarantees long service life and smooth running. The<br />
feed area <strong>for</strong> inert gas or vacuum is designed to prevent<br />
oxidation of the polymer, thus ensuring trouble-free spinning.<br />
Specially matched screw and barrel materials result in good<br />
sliding properties and low wear.<br />
26 <strong>IDY</strong> solutions – <strong>Oerlikon</strong> <strong>Barmag</strong><br />
Air-cooled extruder series<br />
These are the perfect choice <strong>for</strong> processing PETP, PA6,<br />
PA66, PP and other spinning polymers in all viscosity ranges<br />
<strong>for</strong> all manmade fiber requirements.<br />
An optional feature offered is the control cabinet, which is<br />
integrated into the extruder frame. This version trans<strong>for</strong>ms<br />
our well-established model into a compact unit with significantly<br />
less wiring.<br />
All versions are available with or without a cooling system <strong>for</strong><br />
the barrel. An injection system introducing master-batches<br />
or liquids into the polymer stream at various locations <strong>for</strong><br />
customized fiber characteristics is also available.<br />
The extruder series ranges from 90-mm to 175-mm screw<br />
diameter and a throughput range from 40 kg/h to 720 kg/h.<br />
Direct spinning<br />
Cost competition in the <strong>IDY</strong> sector is also increasing. There<strong>for</strong>e,<br />
especially <strong>for</strong> high capacity installations/plants, the<br />
direct spinning technology is becoming more and more<br />
attractive. Some of the latest <strong>Oerlikon</strong> <strong>Barmag</strong> <strong>IDY</strong> lines are<br />
already operating successfully in a direct spinning process of<br />
this kind. For this technology, <strong>Oerlikon</strong> <strong>Barmag</strong> can engineer,<br />
design and provide the complete system <strong>for</strong> high IV melt<br />
distribution.
