COLD
FEED TYPE EXTRUDERS
| Cold feed type extruders are constructed with specially designed
screws best suited for cold feeding. The primary components
of each machine are an extruder unit, a temperature control
unit, a drive motor, and a temperature control panel. |
|
FEATURES
& BENEFITS
-
Ordinary temperature rubber in the form of tapes,
pellets or slabs can be fed directly to the extruder, with no
preheating in warmingmills before the extruder.
-
A range of screws is available for a wide variety
of compound and.extrusion applications.
-
During the extrusion process, uniform
temperature and plasticity is applied
to the
.rubber compound to provide greater
in the shape and size of extruded components.
-
Rubber feed to the extruder can be automatic,
reducing the number of operating personnel.
-
An automatic temperature control unit with a
circulating pump controls.barrel
temperature to within ±1¼C, so the shape and size of
the extruded products are uniform.

VENT
TYPE EXTRUDERS
| Single screw vent type extruders have screws of an original
and unique design. The primary components of each machine
are an extruder unit, a temperature control unit, a temperature
control panel, and vacuum pump. Compound can be cold fed to
the feed section. |
|
FEATURES & BENEFITS
- A single, specialty geometry screw and vacuum pump completely
vent bubbles out .of extruded components.
- Screw can be replaced quickly when .necessary.
- The machine is easy to inspect and maintain.
- An automatic temperature control unit, with a .circulating
pump, controls barrel temperature to within ±1¼C, so the
shape and size of the extruded products are uniform.
- Requires a small floor area.

PIN
TYPE EXTRUDERS
| The pin type extruder
incorporates a special design with 60 to 100 pins protruding
from the cylinder wall toward the screw's center. These pins
enhance the mixing and dispersing of the rubber as it is kneaded
between the screw and the cylinder, making the pin type extruder
extremely flexible as a universal extruder that is applicable
to many rubber compound formulations for diverse applications. |
 |
FEATURES & BENEFITS
- Pins enhance mixing
to provide high uniformity in dispersion and plasticization
of material.
- Applicable to a wide
range of rubber compounds.
- Output is 20% to
60% higher than a conventional cold feed type extruder of the
same size.
- Rubber can be extruded
at relatively low temperatures.
- The low energy consumption
(WH/KG) helps keep costs down while.conserving
resources.
- System is self-cleaning.
