As the plastic industry continues to expand rapidly, injection molding machines play a crucial role in both the quantity and variety of plastic products. These machines can mold complex, accurately-sized plastic items, even incorporating metal inserts. Injection molding machines are extensively used in numerous sectors, including national defense, automotive, electromechanical, transportation, building materials, packaging, agriculture, education, healthcare, and everyday life. With the market flooded with various models and types, selecting the right injection molding machine can be a daunting task for users.

The selection of an injection molding machine involves either longitudinal or horizontal comparisons. "Longitudinal" refers to checking if the main technical parameters meet industry standards. "Horizontal" involves comparing technical parameters of similar machines domestically and internationally. Depending on the material, shape, structure, and application of the products, select the machine based on mold structure, quality, precision, cavity number, channel type and structure, shape, size, and production capacity.
Machine stability is reflected in the smooth, noise-free operation of the mold and injection system during each cycle. This requires precise mechanical manufacturing and assembly, along with well-designed structures. Reliability and lifespan depend on the system rigidity of the die-closing mechanism and the quality of components like templates, tie rods, and screw drive spindles.
A reliable low-voltage protection system is crucial for ensuring both machine and operator safety. Injection molding machines should implement combined electrical, mechanical, and hydraulic safety systems. These should include mold safety features and personal protection mechanisms, such as halting operations if the safety door is not properly closed or if foreign objects are detected in the mold.
Modern injection molding machines should support manual, semi-automatic, and fully automatic operations. With a well-designed mold, they can fully automate injection processes, including product ejection and dropping. Enhanced automation can be achieved with robots and programmable core-pulling, hydraulic nozzle control, and rapid heating channel probe functions.
High production efficiency is signified by short molding cycles under normal injection conditions. This requires high-quality hydraulic, electronic components, and precision manufacturing to ensure system sensitivity and repeat accuracy, which are critical for efficient operation.
Choosing the right machine has a significant impact on productivity and operations. Adhering to the criteria mentioned above can help users select a suitable injection molding machine.
