Brochure DownloadDescription
The PVC / PBAT / PBS twin screw pelletizing extrusion machine from Zhenfa adopts a parallel counter-rotating twin screw design. It efficiently mixes and plasticizes PVC powder, biodegradable plastics (PBAT, PBS), and additives. Using die-face hot cutting and vibration cooling, it produces uniform, high-quality plastic pellets suitable for pipes, sheets, profiles, cable compounds, and injection molding applications.
Key Features & Advantages
- Efficient Mixing: Twin screw counter-rotating design with precision-ground, hardened gear reducers ensures long service life, low energy consumption, and stable operation【486†P20250624_Zhenfa_PVC_TwinScrewPelletizer】.
- Die-Face Cutting System: Rear-knob hinged die head with high-speed, stepless cutting blades ensures continuous and stable pelletizing.
- Vibration Cooling Bed: Dual-layer design quickly cools and separates pellets from dust and fines, preventing agglomeration.
- Stainless Steel Storage Tank: Ensures clean storage and easy downstream packaging or conveying.
-
Operation Control System:
- Traditional operator control type – simple and intuitive.
- HMI microcomputer control system with touchscreen, intelligent temperature control, motor interlock, PLC programming, alarm records, and bilingual (Chinese/English) interface.
- PC-based control system for enhanced data management and synchronization with other equipment.
- Easy Maintenance: Quick-open die head and cutting system simplify cleaning and replacement; modular design reduces downtime.
