Customizable Material Options with IBM Injection Blow Molding Machine for

Product Specification

A. Process integration • Advantages of one-step molding: It integrates injection molding of preforms and blow molding of containers. There is no need to manufacture preforms separately, which reduces intermediate links (such as preform handling and secondary heating) and improves production continuity. • High precision: The injection molding process can accurately control the size and wall thickness of the preform. The preform is evenly heated during blow molding, and the size error of the finished product is small (such as more regular details such as bottle mouth thread and bottle body curvature).

B. Production efficiency and automation • High-speed mass production: Some models can realize the "injection molding-blow molding-demolding" cycle automation with a short cycle (such as producing dozens of containers per minute), which is suitable for large-scale industrial production. • Reduce manual intervention: The entire process from raw material input to finished product output is automated, reducing labor costs and reducing human operation errors.

C. Product quality characteristics • Wall thickness uniformity: During the blow molding process, the air pressure acts evenly on the preform, and the wall thickness of the finished product is more evenly distributed (such as beverage bottles, cosmetic bottles, etc.), with better strength and sealing. • Surface finish: The injection mold has high precision, and the surface of the product after blow molding is smooth, without obvious parting lines or burrs, which is suitable for products with high appearance requirements (such as transparent packaging bottles). • High material utilization rate: The parison is directly blow-molded, with less waste. Compared with the traditional step-by-step process (such as extrusion blow molding), the loss of raw materials is reduced by 10%-20%.

D. ​​Equipment adaptability and flexibility • Multi-specification production: By replacing the mold and adjusting the process parameters (such as injection pressure, blow molding air pressure), containers with different capacities (from a few milliliters to several liters) and shapes (round bottles, square bottles, special-shaped bottles) can be produced. • Material compatibility: It is suitable for thermoplastics such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), meeting the packaging needs of the food, medicine, daily chemical and other industries.

E. Energy consumption and cost • Energy consumption is concentrated and optimized: The heat energy in the injection and blow molding process can be partially recycled (such as the waste heat of the parison is used for blow molding heating), which reduces the energy consumption of step-by-step equipment by about 15%. • High initial investment: The equipment structure is complex (including injection molding system, blow molding mold frame, hydraulic/pneumatic system, etc.), and the purchase cost is higher than that of single-function equipment, but long-term mass production can dilute the cost.

F. Targeted application scenarios • Suitable for high-precision requirements: such as medicine bottles (need to be sterile and tightly sealed), cosmetic bottles (high appearance requirements), food packaging bottles (leakage prevention), etc. • Not suitable for oversized or overly complex structures: Limited by the size of injection and blow molding molds, it is difficult to produce oversized containers (such as industrial barrels) or products with extremely complex structures
