TWO-Stage Injection
By uncoupling the extrusion and injection functions, YUS??s two stage PET injection design provides a number of advantages over conventional reciprocating screw designs including:
* Homogeneous mall: from continuous plasticizing throughout the molding cycle
* High energy efficiency: achieved through the use of smaller screw sizes
* Special PET screw designs: special screws provide more flexibility to mold a wide range of PET resins and colors
* Uniform malt to each cavity: optional melt channel re-mixers gently mix the molten PET stream before injection
* Minimal AA generation: on-line control of screw rotation, transfer speeds, and injection and hold functions minimize acetaldehyde levels for high quality performs.

Performance Improvements
Cooling Technology: Internal post-mold cooling enables robot systems to run up to 15% faster. Cooling operates while performs are cooling in the take-off plate.
Fast, Compact Design: 48,56,72 and 96 cavities sys-tems with robots occupy 15% less factory floor space.
Simplified Tooling Changes: Standard features include:
* Mold multi-position take-off plate as-sembly for fast, one-piece installation
* Integrated mold heat packages allow automatic configuration for each mold cavi-tation and pitch
* Integrated robot controls.

Robot of injection machine
YUS robot systems are ideally for applications compatibility with ex-isting and new tooling. and for performs with relatively thin walls. When combined with YUS??s multi-position take-off plates and cooling technologies, these systems offer :
* Fast cycle times
* Quality performs
* Reliable operation
