Advanced Vented Single Screw Extrusion Technology
The SWT-120D adopts a Φ120mm vented single screw extruder with a 40:1 L/D ratio. The extruder uses a 132KW permanent magnet synchronous motor and high-quality 38CrMoAlA screw and barrel structure.
The vacuum venting system effectively removes moisture and impurities during PET melting, improving melt quality and production stability.
Efficient Vacuum Degassing System
PET materials are moisture‑sensitive. Our SWT‑120D PET Sheet Production Line features a vacuum extraction system to eliminate moisture and impurities during melting. Vacuum system components: ‑ Multi‑stage vacuum unit ‑ 7.5KW rotary vane pump ‑ 3KW Roots pump‑ Stainless‑steel vacuum pipingThis degassing system improves: PET sheet transparency, Surface quality, Processing stability, Production efficiency.
Precision PET Sheet Forming And Calendering System
This PET sheet line adopts precision coat‑hanger die and three‑roll calendering for consistent thickness and premium surface quality.
