THE FEATURE OF PVC PIPE EXTRUSION MACHINE:
Conical twin-screw extruder: It equipped with forced fixed-quantity
material feeding system, automatic temperature control system,
vacuum exhaust system and automatic speed control system.
This structure assures accurate controlling for the material
temperature, plasticization stability and greatly improving
production speed. The main motor is direct convertor or frequency
convertor.
PVC extruding molds: Material is high quality 40Cr. Molds surface
is dealt with polishing and chrome plating. it adopts the structure
of multiple head spiral. The melt has low pressure. Extruding at
high quantity, the die head still maintain low temperature.
Vacuum calibrating water tank: The material of body is high
hardness and good quality stainless steel board. It is
high-pressure resistance, corrosion-resistance and two-stage for
large diameter pipe.
Electricity controls water temperature.
The nozzle material is ABS engineering plastic. The frame of the
machine can be adjusted three dimensions. The moving from front to
back adopt cycloid reducer drive and up & down and left & right
adopt screw adjustment.
Water spray cooling tank: The body is made of stainless steel and
the shade is transparent soft PVC curtain. Stainless steel float
adjusts water level and electricity controls water temperature. The
nozzle material is ABS engineering plastic.
Haul-off machine: It adopts frequency conversion approach. Every
traction frame transfers with chain which ensures every track
moving simultaneously. It is pneumatic flexibility clamping.
Cutting machine: It is planetary cutting for large diameter. The
blade takes rotation and cutting part and inserting blade part take
revolution. It has angle cutting structure, pneumatic aluminum half
clamping and cleaning device.
Control system: We can offer Siemens PLC controlling system which
is intelligent controlling system. Also we can offer ordinary
controlling system which use Siemens electrical parts, Omron
temperature controller. Operation is simple.
