Independent Twin-Screw Injection System

The independent twin-screw injection system consists of a dedicated plasticizing screw and a separate injection screw. The plasticizing screw is responsible for the feeding, compression, melting, and venting of PET material, while the injection screw handles melt metering, accumulation, and the injection phase.

Technical Highlights

Decoupled Process for Superior Quality: The complete separation of plasticizing and injection enables continuous plasticizing throughout the cycle. This provides longer, more uniform melting with greater capacity, which effectively controls acetaldehyde generation and improves product quality.

Parallel Operation for Maximum Efficiency: The specialized design allows the plasticizing of the next shot to occur while the mold is cooling. This parallel workflow saves significant time on the injection and holding pressure phases compared to conventional machines, leading to a markedly shorter overall cycle and higher production efficiency.
