Anfu Adopted suitable screw
design and machine configuration, it is widely used in manufacturing PP or PC
hollow profile boards of various specifications(Max. width: 2300mm; thickness
range: 2mm-12mm). It is widely used in the fields of advertisement, decoration,
sound-proof, packing. Because it is featured by light-weight, strong, dampproof,
anticorrosive advantages, it trends to replace the paper carton gradually and
become the first choic to make packing cases.
? Extruder: The special designed screw and the advanced temperature control
system ensure the good plasticizing, stable extrusion and high output.
? Screen changer: it is of hydraulic style fast screen changer and ensures the
short course of the exchanging filters. Double filters and special leakage-proof
structure guarantee its stable performance.
? Die: Made of super quality alloy and adopted adjustable restrictor bars,
provide the even pressure of the plastic flow at the die lips. It ensures even
thickness of the board with adjustable lips
? Vacuum calibrator: The vacuum system and calibrating system including a
heat-convection system array interleaved. This kind of design guarantees the
high precise degree of the calibration. The vacuum system consists of two
independent subsystems, which is equipped with many pieces three point type
closed loop vacuum line. Each closed loop is equipped with vacuum regulating
system and vacuum display system. This guarantees the good calibration and the
smooth surface of the board.
? Take-off unit: There are two haul-off units. First one consists of multi-rolls
and is driven by a strong motor with a speed reducer with a big gear ratio. It
has strong take-off strength and performs well at slow speed so that it can draw
the board up from the calibrator evenly and synchronally. Second one is put
after the infrared stabilizing oven. The slit unit fixed on the take-off unit
ensures the smooth cut of the edges.
? Infrared stabilizing oven: Its advanced huge area conductive heating style can
relieve the stress of the products so as to ensure the board is flat.
? cutting machine: Setting accurate instant fixing-length cutting and automatic
ascend and drop unloading system; the special alloy steel sharp blade ensures a
good cut effect.
? The electrical control system of the line: Provide two kinds of control
system: first: automatic control by the conventional control panel for the line;
Second: a microprocessor unit (PLC) which can act as a central control of the
related parameters of the machines: (screw revolutions, temperatures, pressure,
alarms, out-put etc ) and be optimized with the operation characteristics of the
