Plastic Blow molding machines for the production of 5L hdpe
Introduction
We are one of the leading names of the industry known for
manufacturing superior quality Extrusion Blow Moulding Machine. We
are manufacturing this machine using optimum quality raw material
with a combination of sophisticated technology.
We are having the finest experts associated with us taking charge
of the manufacturing process. Each machine manufactured by us need
to pass through strict quality check process under various
parameters before reaching the hands of the customers using the
same.
We are offering this machine in wide range with various
specifications at an affordable price range. The design is compact
and consumes less power.
DIE HEAD
Head mode: the continuous extrusion head is designed with material
center coming-in type and removing the plastic melting line on the
product surface, easily for material or color change, saving the
time & material cost with speedy operation.
EXTRUSION SYSTEM
Gradient mixing type with high-speed energy saving design,
gradually changed screw with same distance and different deep.
Material of screw: High quality nitriding steel 38CrMoAlA,with
nitriding surface HV≥800,brittleness≤2. Material of barrel: High
quality nitriding steel 38CrMoAlA,with nitriding surface
HV≥900,brittleness≤2.
HYDRAULIC SYSTEM
The main hydraulic system is mainly composed of motor, pump,
pressure regulating valve block, reversing valve blocks, cylinders
and oil chillers. It controls platens open & close, carriage up &
down, extrusion system up & down, blow pin actions, or even
spinning cut and so on.
ELECTRICAL CONTROL
The electrical control system is composed of operation panel,
temperature control module, PLC, input & output module, proportion
board, contactors, voltage stabilized source, air swtiches, mid
relays, proximity switches, inverter and motors. The operation
panel contains power switch, touch screen, alarm, hot cutter knob,
auto cycle button, emergency stop button, action reversion button,
extruding speed button.
MECHANICAL STRUCTURE
Clamping unit is composed of front & back platens, clamping seat,
carriage seat, mould stroking & clamping hydraulic cylinders,
synchronizing mechanism, with the structure of nether crank design.
Platen movements open & close, carriage up & down is assisted with
linear guide rails & ball bearing sliders to increase action
smoothness and position precision. The end positions & slow speed
positions are controlled by proximity switches or transducers.
AIR & WATER SUPPLY
The pneumatic system contains air cylinder, air valves, air
filters, air tubes, fast plugs and so on, for controlling the
actions of head inner blowing, blow pin blowing, auto-deflashing,
or pushing in & out for some special moulds. The necessary air
pressure is 0.6~0.8 Mpa, air consumption is 0.8~1.0 M3/min. The
water system contains water distributing blocks, ball valves,
tubes, connectors and so on, for chilling the screw & barrel, hard
gear box, blowing units and moulds. The necessary water pressure is
0.2~0.4 Mpa, water consumption is 4500L/hour.
