Car water tank plastic blow moulding machine SRB70S-1 is widely
used in car water tank making field, auto vent pipes and hollow
parts, engine oil bottle packing field, cooking oil tank packing
field, petrol tank making field and toys making field, also used
for other round or square jars, containers and tanks. In normal
production, the cycle time is about 50 seconds. Its production
capacity is 70 pcs/hour, daily output is 1700 tanks. The key
technical points lie in precise die and core size, blow pin head
diameter and design, also the suitable depth of mould cutting
overflow grooves to insure the on-line deflashing result. Besides
EBM machine, we also provide on-line auto deflashing plastic bottle
moulds, and auxiliary machines such as auto-loader, color mixer,
scraps crusher, water chiller, air compressor, air accumulating
tank, leakage tester, in-mold labeling machine and so on. We help
customers to get one stop service of manufacturing, exporting and

The extrusion system includes gear box, extrusioin motor, inverter,
screw, barrel, head and die. The extruder adopts gradient mixing
type with high-speed energy saving design. 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. The
head runner has good design and head matel is processed for higher
hardness. The die and core will be made according to your product
design and size.
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. Our nether bent arm central clamping
structure insures the clamping force bearing to mould in balance,
easy for scraps auto-deflashing, also good for mould's lifespan.
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.
The 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. Our hydraulic system has been updated with
proportion valve and mechanical shuttle valve for action stability
and precision. It insures the oil pressure output fast but smooth,
action performance is quick but with less impact.
Water & Air 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 0.4~0.6 Mpa, air consumption is 0.6~0.8 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 2500L/hour.
our machine supports auto-deflashing control system and pneumatic
hardware, the scraps can be on-line removed automatically through
auto-deflashing mould. Scraps fall down and slide outside of
machine through a slide channel. The finished products are pushed
out from another side together with platen carriage down action
with the guidance of bottle collective shelves. The conveyer system
can be equipped to take scraps into crusher, and convey the
finished products to leakage tester or packing table. During the
producing period, the machine can work automatically without the
Working Flow Arrangement
The whole producing line totally need 2 workers. Worker No.1 takes
charge of material mixing and feeding, he collects the crushed
scraps into color mixer, operate the material mixing of new
material, crushed material and color master batch. After mixing he
carries material into material source tank, the auto-loader will
feed material automatically. The other worker takes charge of
bottle packing, and take the packaged bottles into storage area.
