The specially designed screw and the
advanced controlling system ensure
high output and stable extruding.
1, auto spiral screw feeder
2, drying hopper
3, siemens motor
4, aluminum heater
5, bimetallic screw
There are two tractors. The first one is high
power,high reduction ratio, multi-roller type,
well low-speed operation, high traction and
is able to draw the plate up from the
calibrating table evenly and synchronal.
Quick screen changer of hydraulic
system ensure the continuously working
of screen changing.Double position
combined with special sealing structure
guarantee stable operation of screen changer.
The heating oven made by 304 stainless steel,
the heating oven is equipped with separately
temperature control system for each zone to
ensure the heating to be uniform,
4 meter lengths of heating oven is necessary,
Mould adopts high-quality alloy steel and
throttling device to ensure even pressure
of feed influent at the mould lips, and also
differential action of up-down piece
guarantee even thickness of the plate.
1, customized width and thickness
2, with hydraulic screen changer
3, with melting pump
4, high quality mold for precisionthickness
Heating exchanging and cooling system
of quick speed in calibrating system alternate
effectively and ordinally with vacuum system,
which ensures calibrating precision.
Vacuum system composes two independent
subsystems and each is equipped with several
fixed circulating vacuum lines three-point type.
Meanwhile, each line carries vacuum regulating
system and display system that realize even
stable vacuum degree of plate surface.
