This 32-cavity pin-valve hot runner system is specifically designed for PET pre-forms, PET transparent precision plastic parts, and food-grade PET products. It adopts a 32-cavity balanced distribution layout in one mold and is equipped with special high-temperature-resistant and anti-crystallization pin-valve hot nozzles. It is targeted at solving industry pain points such as the easy crystallization, stringing, poor fluidity, uneven multi-cavity filling, gate whitening, and stringing tails of PET. It is suitable for the automated injection-molding production of large-quantity, highly transparent, and high-precision PET plastic parts, and is widely used in fields such as beverage pre-forms, food packaging, transparent accessories, and medical PET consumables.
