In high-cavity PET preform mold systems, real competitiveness is not defined by a single parameter, but by long-term stability, molding consistency, and overall production efficiency.As demand continues to grow in the beverage, bottled water, edible oil, and food packaging industries, the 72-cavity PET preform mold has become a mainstream configuration for medium-to-high capacity production lines. Compared with low-cavity molds, 72-cavity systems require significantly higher standards in hot runner design, cooling structure, machining precision, and assembly consistency, making them a strong indicator of a manufacturer's engineering capability.
