A. Integrated molding, simplified production process
Complete two processes at one time: The injection blow molding machine integrates the two steps of "injection molding preform" and "blow molding" on the same equipment. There is no need to transfer the preform from the injection molding machine to the blow molding machine as in the traditional process, reducing the transportation, storage and secondary processing of the intermediate links.
Reduce manual intervention: The full automation operation reduces the errors in manual handling, positioning and other links, while saving labor costs, which is especially suitable for large-scale batch production.

B. High product precision and stable quality
Good dimensional consistency: Since the injection molding and blow molding of the preform are completed on the same equipment, and the mold positioning is accurate (usually mechanical linkage or servo system control), the wall thickness uniformity and bottle mouth size accuracy (such as thread fit) of the product are much higher than the step-by-step process, which is especially suitable for products with high sealing performance requirements (such as medicine bottles and cosmetic bottles).
No parting line or hidden parting line: During the blow molding process, the preform is formed in a closed mold, avoiding the secondary mold error that may occur in the step-by-step process, and the product surface is smoother and the appearance quality is better.

C. High production efficiency and low energy consumption
Shortened molding cycle: The integrated process reduces the process conversion time. The single-mold production cycle is usually 20%-30% shorter than the "injection molding + blow molding" step-by-step process, which is especially suitable for small-size and large-volume products (such as 50-500ml plastic bottles).
Outstanding energy saving: Compared with the two devices running separately, the power system and heating system of the injection blow molding machine can be shared, reducing energy loss; at the same time, the preform directly enters the blow molding link after injection molding, and the waste heat can be used, reducing the energy consumption of secondary heating.

D. Clear scope of application and strong pertinence
Suitable for small and medium-sized hollow products: Injection blow molding machines are better at producing hollow products with smaller volume (usually less than 500ml) and relatively simple structure, such as medicinal bottles, cosmetic bottles, food packaging bottles, small-capacity chemical containers, etc.
Compatible with a variety of plastic materials: mainly suitable for thermoplastics, such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), etc., especially for crystalline plastics (such as PP) The molding effect is excellent.

E. Compact equipment structure and small footprint
The injection blow molding machine integrates the injection unit, blow molding unit, demolding unit, etc. on a frame. The overall structure is compact. Compared with the injection molding machine and blow molding machine placed separately, it can save 30%-50% of the workshop floor space, which is suitable for production environments with limited space.

F. High degree of automation and easy to realize intelligence
Modern injection blow molding machines are generally equipped with PLC control systems and touch screen operation interfaces, which can realize accurate setting and monitoring of parameters (such as temperature, pressure, and time); some high-end models also support docking with the MES system to realize intelligent functions such as production data traceability and remote diagnosis, which is in line with the development trend of Industry 4.0.

G. Limitations and applicable scenarios
Not suitable for large products: Due to the limited clamping force and blow molding stroke of the equipment, it is difficult to produce products with large capacity (such as more than 1L) or complex structures (such as special-shaped bottles, containers with handles). Such products are more suitable for traditional extrusion blow molding or stretch blow molding processes.
High mold cost: Injection blow molds need to meet the precision requirements of injection molding and blow molding at the same time, with more complex structures and slightly higher initial investment costs than ordinary injection molding or blow molding molds. Therefore, they are more suitable for large-scale, long-term and stable production needs.
