When it comes to PET preform manufacturing, efficiency, precision, and consistency are non-negotiable. That’s why Lisong’s PET Preform Injection System stands out as a premier solution for producers aiming to scale their output without sacrificing quality. Designed with clamping forces ranging from 2,000 to 6,000 kN, our machines are engineered to handle everything from small-scale runs to mass production with unparalleled reliability.

At the heart of our system is the maintenance-free clamping mechanism. Unlike traditional systems that require frequent lubrication and adjustment, our clamping unit operates without oil in the mold area, eliminating contamination risks and ensuring compliance with stringent food safety standards. This is particularly crucial for PET preforms used in food and beverage packaging, where purity and hygiene are paramount.

But it’s not just about cleanliness—it’s about performance. Our direct pressure locking system ensures minimal template deformation and perfect parallelism with the mold, resulting in consistent cavity-to-cavity uniformity. Whether you’re running 24 cavities or 144, each preform meets exact specifications, reducing waste and improving yield.

Another standout feature is the super-sensitive low-pressure mold protection, which operates at just 1/30 of the clamping force. This technology detects obstructions or misalignments during closing, preventing costly damage to precision molds and reducing downtime for repairs.

Coupled with a PET-specific twin-screw injection unit, our system delivers uniform plasticization, faster cycle times, and higher shot weights. The screw design allows for simultaneous injection and material storage, optimizing melt homogeneity and boosting overall productivity.

From water bottles to custom containers, Lisong’s PET Injection System is built to deliver more preforms, faster, and with exceptional quality. Let us help you transform your production line into a model of efficiency and reliability.
