Seamless Integration IBM Injection Blow Molding Machine for Beverage Bottles

Product Specification

A. No flash during the molding process, low post-processing cost • The mold clamping accuracy of the injection blow molding machine is extremely high, and the pressure control in the injection and blow molding stages is precise, so the product is almost free of flash and burrs after molding. Compared with the extra material edges that may be generated by the traditional step-by-step process, there is no need for additional post-processing procedures such as trimming and grinding, which not only saves manpower and time costs, but also avoids damage to the surface of the product during post-processing (such as scratches and deformation). • This feature is particularly important for products with strict appearance requirements (such as cosmetic bottles and high-end food packaging), which can directly improve the product's factory qualification rate.

B. Complex bottle mouth structure can be formed in one step • For products with anti-theft rings, scale lines, and special-shaped bottle mouths (such as bayonet mouths and spiral grooves), the injection blow molding machine can directly integrate these structures into the preform during the injection molding stage, and retain them completely after blow molding without the need for secondary processing. • For example, the aluminum cap of the medicinal vial with the bayonet mouth and the anti-theft thread of the beverage bottle can be formed in one step by the injection blow molding machine to ensure structural accuracy and sealing, while the step-by-step process may require additional bottle mouth processing steps, increasing the risk of error.

C. Refined temperature control, adaptable to special materials • The injection blow molding machine is equipped with a multi-stage heating system (such as barrel segment heating, mold temperature control), which can accurately adjust the temperature according to the melting characteristics of different plastic materials (such as melting point, fluidity). For example, when processing PET, the crystallization speed needs to be controlled, and when processing PP, it is necessary to avoid degradation caused by local overheating. The temperature control accuracy of the injection blow molding machine (usually ±1°C) can meet these special requirements. • For modified plastics (such as materials with added glass fiber and flame retardants), stable temperature control can reduce material performance fluctuations and ensure the mechanical strength and weather resistance of the products.

D. ​​Fast mold change design, adaptable to multi-variety production • Modern injection blow molding machines generally use fast mold change systems (such as hydraulic clamping, positioning pin fast docking). When changing molds of different specifications, the downtime can be shortened to less than 30 minutes, which is much lower than the 1-2 hours of traditional equipment. • This feature is suitable for production scenarios that require frequent switching of product models (such as multi-specification packaging bottles of cosmetic companies and different dosage bottles of pharmaceutical companies), which improves the flexibility of the production line.

E. Better environmental protection, in line with green production standards • In addition to the high material utilization rate mentioned above, the power system of the injection blow molding machine (such as servo motor) has lower energy consumption, and less waste gas and waste material emissions during the production process (no flash waste, low material loss). • Some equipment can also be equipped with a recycling system to crush a small amount of unqualified products and then re-mix them into the raw materials (must meet the material characteristics) to achieve recycling, reduce plastic pollution, and meet the "dual carbon" goals and environmental protection regulations.

F. Suitable for the production of thin-walled products and reduce material costs • With precise injection pressure and blow molding tension control, the injection blow molding machine can produce hollow products with thinner wall thickness (such as 0.3-0.5mm), greatly reducing the amount of material while ensuring strength. • For example, small beverage bottles, sample trial containers, etc., the injection blow molding process can save 10%-15% of plastic raw materials compared to traditional processes, and the cost advantage is significant in long-term mass production.
