Sheet extrusion melt pumps are critical equipment in the plastic processing industry, primarily used in sheet extrusion production lines. Their core function is to achieve a stable and efficient extrusion process by precisely controlling the flow rate and pressure of high-temperature, high-viscosity polymer melts.
Core Advantages
Stable Flow and Pressure
Eliminates the impact of extruder screw pulsation on pressure, ensuring the stability and continuity of melt delivery. This significantly improves the dimensional accuracy and thickness uniformity of the sheet.
Enhanced Production Efficiency
Reduces the backpressure of the extruder, thereby lowering energy consumption.
Extends the service life of the screw and barrel.
Supports low-temperature extrusion, reducing both energy consumption and production costs.
Improved Product Quality
Precisely controls the melt flow rate, reducing the scrap rate.
Optimizes the melt channel design to avoid residue affecting sheet quality.
Adapts to a wide viscosity range (1–40,000 Pa·s), meeting the requirements of different formulations.
Adaptability to High Temperature and High Pressure Conditions
Can operate stably under conditions of ≤350°C and 0–40 MPa, suitable for processing high-viscosity
polymers such as PET, PP, and PS.
Application Scenarios
Sheet extrusion melt pumps are widely used in the following fields:
Packaging Materials: Producing high-precision sheets such as food packaging films and pharmaceutical packaging films.
Optical Materials: Manufacturing optical-grade sheets such as light guide plates and diffuser plates.
Industrial Materials: Producing industrial-use sheets such as insulating materials and flame-retardant sheets.
Special Functional Sheets: Such as antistatic sheets, antibacterial sheets, etc.
