Twin screw extruders (TSE's) and systems--Leistritz manufactures twin screw extruders (12 to 260 mm) used for compounding, reactive extrusion, devolatilization and direct extrusion
. Services include a fully equipped process laboratory and TSE workshops.
* Direct extrusion
for sheet, film, fibers and profiles
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.
Due to the lack of published information on the processing conditions that extrusion processors use to produce specific geometries across multiple materials, the best way for a design engineer to specify a material For a particular multilumen design without his or her having direct extrusion
experience is to discuss the dimensional and functional performance requirements of the tubing with the processor so that relevant processing experience can be relied upon to shorten the cost and timeline to produce unique solutions to product development initiatives.
Sofabran gives remarkable direct extrusion
results and is easy to use in industrial processes.
A larger amount of shear deformation by ES extrusion can be introduced than that by direct extrusion
with the same extrusion ratio.
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.
However, when PP/EPDM/HDPE (70/20/10) blend was prepared by direct extrusion
, an obscure interface forms between PP and HDPE (Fig.
The process of extrusion, in the case of ACB extrusion press (***-Loire, 1976) of 2500 tons-force (arround 24.5 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.
