Injection blow molding machines have more features in terms of
automation, environmental performance, maintenance convenience,
process scalability, etc.:
. Automation and intelligent upgrade
. Full servo drive technology ◦ The new generation of injection
blow molding machines uses servo motors to drive injection, mold
opening and closing, blow molding and other actions, with a
positioning accuracy of ±0.01mm, and a response speed that is 30%
faster than traditional hydraulic systems (such as injection speed
acceleration time from 0 to 200mm/s <0.1 second), and energy
consumption is reduced by another 20%-30%. ◦ Case: A certain brand
of servo injection blow molding machine produces 100ml cosmetic
bottles, with an energy consumption of only 0.03kWh/bottle, saving
0.02kWh/bottle compared to hydraulic models. Intelligent process
optimization system ◦ The control system equipped with AI
algorithms can automatically optimize parameters (such as real-time
adjustment of injection speed according to raw material temperature
and pressure fluctuations), reduce manual machine adjustment time,
and control the defect rate below 0.5% (the defect rate of
traditional models is about 1%-2%). ◦ Supports real-time monitoring
of OEE (overall equipment efficiency). Data such as production
capacity, energy consumption, and fault records can be viewed
through the touch screen, which is convenient for digital
management of the factory.
. Environmental protection and energy-saving design . Low noise and
low pollution ◦ The operating noise of the servo system is less
than 75dB (about 85dB for the hydraulic system), which meets the
environmental protection standards of the workshop; the mold
cooling adopts a circulating water system, and the water resource
utilization rate is greater than 95%, reducing industrial
wastewater discharge. ◦ Some models are equipped with exhaust gas
collection devices. For the irritating gases generated during the
production of materials such as PVC, they are discharged after
being filtered through activated carbon, which meets the VOCs
emission standards. Waste recycling and energy-saving accessories ◦
It comes with a bottle embryo sprue material crushing device, which
can crush the sprue material (about 5% of the raw materials)
generated during the injection process and directly reuse it in
production, reducing the cost of raw materials (based on an annual
output of 10 million bottles, it can save about 50,000 yuan in raw
material costs). ◦ The heating system uses electromagnetic
induction heating, with a heating efficiency of >90% (the
efficiency of traditional resistance heating is about 60%), and the
surface temperature of the heating coil is <50℃, which reduces
the heat radiation in the workshop.
. Maintenance and operation convenience . Modular structure design
Each unit of the equipment (injection module, blow molding module,
control system) is installed in a modular manner. When replacing
parts, there is no need to disassemble the entire unit. For
example, it only takes 2 hours to replace the injection screw
(traditional models take 4-5 hours), and the maintenance efficiency
is increased by 50%. ◦ Key components (such as mold guide pillars
and screws) use self-lubricating materials (such as hard chrome
plating + PTFE coating), and the maintenance cycle is extended to
5000 hours (about 2000 hours for ordinary parts). Human-computer
interaction optimization ◦ The touch screen supports multi-language
switching (Chinese/English/Japanese, etc.), the operation interface
is graphically displayed, and the training time for novices is less
than 1 day; the fault alarm system can display the problem code in
real time (such as "E003" means that the mold is not locked) and
provide solution prompts.
. Process expansion and special functions . Multi-layer
co-injection blow molding technology ◦ Some high-end models support
2-5 layers of co-injection blow molding, such as inner layer PE
(food contact) + outer layer EVOH (oxygen barrier) + middle
adhesive layer, which is used to produce high barrier sauce bottles
with oxygen transmission rate <0.05cc/day (single-layer bottle
is about 0.5cc/day). Embedded accessories integration ◦ Metal
threaded inserts, sealing rings and other accessories can be
directly embedded in the molding process. For example, when
producing medical bottles with threaded caps, the insert
positioning accuracy is ≤0.1mm to avoid assembly errors in the
later process. Special material adaptability ◦ Optimize the screw
structure (length-to-diameter ratio L/D=28-30) for biodegradable
materials (such as PLA, PBAT) to avoid thermal degradation of the
material. The tensile strength of the molded degradable bottle is
≥30MPa, which meets the ASTM D6400 standard.
. Product post-processing integration . Online inspection and
sorting ◦ Equipped with a visual inspection system, it can detect
online defects in bottle thread and cracks on the bottle body, with
an inspection speed of 500 bottles/minute and a sorting accuracy of
>99.9%, reducing the cost of manual quality inspection (based on
an annual output of 5 million bottles, it can save 2-3 quality
inspection personnel). Online printing and labeling ◦ Some models
integrate thermal transfer or screen printing modules, and the
pattern is directly printed on the bottle body after molding. The
overprint accuracy is ≤0.3mm, which is suitable for small-batch
customized production (such as customized toiletries bottles for
hotels).
. Safety protection design • Multiple safety interlocks: The mold
area and heating area are equipped with infrared sensing devices,
and the equipment automatically slows down or stops when people
approach; the hydraulic system is equipped with pressure overload
protection, and the pressure is automatically relieved when the
pressure exceeds 110% of the set value to avoid the risk of pipe
explosion. • Fireproof design: The outer layer of the heating coil
is wrapped with heat insulation cotton + metal mesh to prevent the
molten raw materials from dripping and causing fire; the electrical
cabinet has a built-in temperature sensor, which automatically
starts the cooling fan when it exceeds 60°C. Summary The advanced
features of the injection blow molding machine are mainly developed
around "intelligence, greening, and flexibility", which not only
improves production efficiency, but also meets the diversified
needs of high-end products, environmentally friendly materials,
customized production, etc. In practical applications, these
features can help companies reduce costs and improve product
competitiveness, especially suitable for large-scale production
scenarios with high requirements for automation and product
precision.
