Injection blow molding machines have more features in terms of automation, environmental performance, maintenance convenience, process scalability, etc.:

一. Automation and intelligent upgrade
1. 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. 2. 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.

二. Environmental protection and energy-saving design

1. 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. 2. 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.

三. Maintenance and operation convenience

1. 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). 2. 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.

四. Process expansion and special functions

1. 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). 2. 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. 3. 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.

五. Product post-processing integration

1. 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). 2. 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).

六. 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.
