High-Purity Raw Material Requirements for Advanced and Energy-Saving IBM Injection Blow Molding Machine

A. Relatively low energy consumption, in line with the energy-saving trend
The injection and blow molding processes of the injection blow molding machine are completed in the same equipment. The heat loss of the parison from injection molding to blow molding is small, and no additional heating and insulation is required. Compared with the split production of "injection molding machine + blow molding machine", it can save 10%-20% of energy consumption.
Some high-end models are equipped with a servo motor drive system, which can accurately adjust the power output according to the production conditions, further reduce standby and operating energy consumption, and meet the requirements of environmentally friendly production.

B. The mold design is complex, but the versatility can be optimized
The mold of the injection blow molding machine needs to integrate the injection cavity, blow molding cavity and demolding mechanism. The structure is complex and the initial design and manufacturing cost is high (especially multi-cavity molds).
However, through modular mold design, molds of different specifications can be replaced on the same equipment to produce products of different capacities or shapes (such as bottles from 5ml to 500ml), which improves the versatility of the equipment to a certain extent.

C. High requirements for raw material purity
During the injection-blow molding process, the raw materials need to undergo high-pressure plasticization and precise molding in the injection molding stage. If the raw materials contain impurities (such as metal particles and unmelted particles), it is easy to cause defects in the parison and even damage the mold or equipment.
Therefore, injection-blow molding machines usually require the use of high-purity pellets (such as medical-grade PP and PET), and need to be combined with precision dryers to remove moisture from the raw materials to avoid bubbles in the products.

D. Application areas focus on high-end market segments
In addition to common pharmaceutical and cosmetic packaging, injection-blow molding machines are also widely used to produce special products with high-precision requirements, such as:
Reagent bottles and infusion bottles in medical devices (must meet sterility and chemical corrosion resistance standards);
Small sealed containers in the electronics industry (such as battery housings and precision component packaging);
Light-proof bottles and leak-proof bottles in high-end food packaging (relying on their excellent sealing properties).

E. The maintenance cost is moderate, and professional operation is required.
The core components of the equipment (such as injection screw, blow molding valve group, turntable bearing) need regular maintenance, but due to the integrated design, the overall maintenance points are less than the split equipment, and the long-term maintenance cost is controllable.
In terms of operation, the operator needs to be familiar with the coordinated control of multiple parameters such as injection temperature, blow molding pressure, turntable speed, etc., especially the process parameters of different materials (such as PP and PET) are quite different, which requires certain technical experience.
