Digital DC, AC vector
or brushless DC drive systems available for all polymer
applications. Connected to gear reducer via fully guarded
matched belts and sheaves allowing interchangeability to meet
different torque and speed requirements.
parallel shaft helical reducer with generous mechanical and
thermal ratings. Self contained splash type oil bath.
cylindrical roller type bearings mounted in a separate thrust
housing with its own oil bath which does not allow any cross
contamination with the gear reducer.
High density class 40
iron casting jacketed for water cooling. The large rectangular
feed hole is tangetial to the bore, which has a pressed fit
removable bimetallic liner. A powder seal is fitted in the rear
of the feed throat. A high capacity hopper complete with sight
glass and dump chute is included. An optional dual shutter
magnet box is also available.
achieved via cast aluminum heating elements, each zone
individually shrouded to guide cooling air directly over barrel
elements. Cooling air provided by externally mounted blowers.
Liquid cooling via closed circuit cooling pump system optionally
bimetallic lined barrel, base material 4140 or JP38 tube steel,
precision machined taper grip flanges threaded and welded for
added strength. Designed for maximum operating pressures of
10,000 PSI. Optional superior corrosion, wear resistant and
vented barrels available.
Heavy duty structural
steel base provides for exact alignment between all
plastification components. Extruder components including motor
control panel and transformer pre wired in a compact unitzed
package for easy component accessibility and minimal
installation time. The front barrel support is heavy duty
weldment with horizontally inserted dowl pins allowing for
linear barrel expansion. The adjustment feature of the front
barrel support allows for precise barrel alignment.
Single stage metering
type, base material pre hardened 4140, chrome plated, colmonoy
hardened flights, and optional coring for cooling. Special
performance designs engineered to suit individual applications
for superior outputs and melt quality available including
barrier type and special mixing sections.
Base mounted control
panel containing microprocessor based temperature controllers,
circuit breakers, ammeters, load contactors, and control
transformer for each barrel and die zone. The drive operator
keypad station containing the following; speed regulation,
start/stop, screw speed indicator, load indicator as well as
other drive data and fault indicators which are remote mounted
near head on operator side. A die heating stepdown transformer
is included. Power requirements 460/3/60 standard, 230/3/60 or
Three piece taper
grip clamp with single swing bolt fastening capability provides
positive seal and alignment between barrel and die flange. Two
piece double hinged swing bolt design and adjustable hinged die
support optionally available.
Deltatech PLC-based touchscreen extrusion control system with
multi microprocessor control, PID temperature control, closed
loop speed control, direct access menus, full drive
synchronization capability, alarm diagnostics, and RS232
