220T PET Preform Injection Molding Machine ZH-220

The ZUIHUI ZH-220 is a dedicated horizontal servo-driven injection molding machine optimized for PET preform production, built for stable high-volume manufacturing with PET resin. Engineered for consistent precision, outstanding plasticizing performance and remarkable energy efficiency, it adopts a mature world-class servo drive system and optimized reinforced double-toggle clamping mechanism. With a clamping force of 2200kN and a theoretical shot weight of 579g, it is equipped with a specially customized low-shear PET screw and barrel. This design effectively reduces shear heat and acetaldehyde generation, ensures uniform melt quality and high transparency of preforms. The machine features rapid injection response, stable pressure closed-loop control and balanced dynamic performance. It perfectly matches multi-cavity preform molds, shortening molding cycles while maintaining stable product weight and uniform wall thickness. It runs smoothly with low noise and sustains long-term continuous production. Ideal for mass production of PET bottle preforms for drinking water, beverages, cosmetics and pharmaceutical packaging.
