A. Better sealing to meet special packaging needs • Products produced by the injection blow molding process (especially the bottle mouth) are formed in one step by injection molding, with a complete thread structure and tight connection with the bottle body. With the precise mold control, it can effectively avoid the leakage caused by poor sealing at the interface in traditional blow molding. • This feature makes it particularly suitable for containing liquids, pastes (such as cosmetics, sauces) or volatile and oxidizable substances (such as essential oils and solvents). It is a key advantage in the medical field (such as vaccine bottles and oral liquid bottles) to ensure the stability of the contents.

B. Support the molding of complex structural products • Although injection blow molding machines are more commonly used for symmetrical products, with the improvement of mold technology and equipment control accuracy, some models can produce products with simple protrusions, grooves or special-shaped bottle mouths. • For example, beverage bottles with anti-theft rings and medicinal dropper bottles with scales can complete these additional structures in one molding through the fine design of the mold cavity, reducing subsequent processing steps.

C. Accurate temperature control system, adapted to material characteristics • The injection blow molding machine is equipped with a multi-stage temperature control system, which can set different temperatures for the injection screw, parison mold, and blow molding mold to meet the plasticization and molding requirements of different materials. • For example, when processing PET, a higher injection temperature (about 270-290℃) is required to ensure fluidity, while the temperature is lower when processing PP (about 180-220℃). The temperature control accuracy of the equipment (within ±1℃) can ensure the stable performance of the material performance and avoid product defects caused by temperature fluctuations.

D. ​​Relatively small footprint and high space utilization • Compared with the split production line of "injection molding machine + blow molding machine", the injection blow molding machine integrates two processes into one equipment frame, especially the turntable structure, which has a compact layout and can reduce the floor space by 30%-50% under the same production capacity. • For small and medium-sized enterprises with limited plant space, this can effectively save site costs and improve the flexibility of workshop layout. 15. Comply with industry compliance requirements • In industries such as medicine and food that have extremely high safety standards, the production process of the injection blow molding machine is easier to achieve full clean control (such as equipped with a closed structure suitable for dust-free workshops, food-grade lubricants, etc.). • At the same time, the equipment can record key parameters in the production process (such as injection pressure, blow molding time, temperature curve, etc.), which is convenient for traceability and meets the audit requirements of industry certifications such as GMP (Good Manufacturing Practice) and FDA (U.S. Food and Drug Administration).
