Italian firm is presenting plants for direct extrusion
of around 5000 lb/hr of PET sheet from 80% to 90% post-consumer bottle flake without predrying, using co-rotating twin-screw extruder with multiple vents.
Twin screw extruders (TSE's) and systems--Leistritz manufactures twin screw extruders (16 to 180 mm) used for compounding, reactive extrusion, devolatilization and direct extrusion

Kiani acts as a consultant for a company in this region that plans to make railroad ties from post-consumer HDPE reinforced with glass-fiber, using a direct extrusion
Teknor Apex has launched new PVC compounds for automotive exterior mouldings that it says enable direct extrusion
of smooth, textured surfaces that stay blemish-free, even after prolonged outdoor exposure.
The reason why direct extrusion
can be done at lower gsms is because it is possible to handle the extruded film at very low gsms, even as low as 8 gsm or less.
Sofabran gives remarkable direct extrusion
results and is easy to use in industrial processes.
This process is divided into two types depending on the direction of motion for metal, the first type is called direct extrusion
which is used in this study as shown in Fig.
One was direct extrusion
, in which PP, EPDM and HDPE pellets were simultaneously added to the twin screw, and directly melt blended.
This step can be bypassed for the direct extrusion
of a sheet or profile.
5 MN) used for metal of brass and copper, is an usual direct extrusion
process as following: stock material (the blank, also called "billet"), in the form of dollops of 220 mm diameter and the length of 250-750 mm, is continuously fed to heating chambers and carried along by a feed-device within (Fig.
