A. Compact structure, optimized floor space • The injection blow molding machine integrates the injection molding and blow molding systems on the same frame. Compared with the combination of split equipment (injection molding machine + blow molding machine), it can save 30%-50% of the workshop floor space, especially suitable for small and medium-sized production enterprises with limited plant space. • The equipment layout is more reasonable, and the moving lines for raw material transportation and product output are shorter, which reduces the interference of workshop logistics and improves the utilization rate of production site.

B. Precise temperature control of the mold and reduces defects • The mold in the injection molding stage is directly cooled and shaped in the mold, and the temperature connection with the subsequent blow molding stage is closer (no secondary heating is required), which can accurately control the temperature distribution of the mold - This is crucial for blow molding: ◦ If the mold temperature is too high, it is easy to "over-stretch" during blow molding, resulting in too thin wall thickness; ◦ If the temperature is too low, the plastic will not be fully fluid, resulting in insufficient blow molding and missing corners. • Precise temperature control can greatly reduce common defects such as "sink marks, bubbles, and deformation", and improve the product qualification rate.

C. Suitable for aseptic production needs • For fields such as medicine and food that have extremely high hygiene requirements, injection blow molding machines can be configured with aseptic-grade designs: ◦ Use stainless steel frames and food-grade lubricants to prevent equipment components from contaminating raw materials; ◦ Equipped with online sterilization systems (such as ultraviolet and ozone disinfection) to sterilize molds and molding areas in real time; ◦ Linked with the clean room air conditioning system to maintain a slightly positive pressure environment inside the equipment to prevent external contaminants from invading. • This feature enables it to meet stringent standards such as GMP (Good Manufacturing Practice) and FDA (U.S. Food and Drug Administration).

D. Low-noise operation advantage • Compared with traditional extrusion blow molding machines (which often generate loud noise due to high-speed screw rotation and material friction), the injection and blow molding actions of injection blow molding machines are smoother, and the overall equipment is more closed. The operating noise can usually be controlled below 80 decibels, which helps to improve the workshop working environment and meet occupational health and safety standards.

E. “Dual” requirements for operator skills • On the one hand, automation and digital control systems reduce the difficulty of basic operations (such as parameter setting, starting and stopping equipment); • On the other hand, if it is necessary to optimize the production process (such as adjusting the thickness of the mold to adapt to different blow molding shapes) or troubleshoot complex faults (such as mold alignment deviation, unstable pressure), the operator is required to master the principles of injection molding and blow molding at the same time and have comprehensive debugging capabilities. Therefore, companies need to train technical personnel in a targeted manner.
