2026-11-14 High Precision Melt Gear Pump for Film, Sheet, Pipe, Pelletizing & EVA Blow Molding
A high-precision melt gear pump, also called an extrusion metering pump or thin-film extrusion pump, is a positive-displacement polymer metering unit widely installed between the extruder and die for plastic pelletizing, EVA blow molding, cast film, blown film, sheet and pipe extrusion lines. It separates upstream screw pulsation and delivers stable, fixed-volume molten polymer flow, which directly improves thickness uniformity, reduces scrap and supports consistent 24/7 extrusion production for thermoplastics including EVA, PE, PP, PS, TPE and filled compounds. Conventional single-screw or tw

2026-11-07 China Origin Polymer Melt Pump, High Precision Stabilized Gear Pump for Synthetic Fiber Twin Screw Ex
If you run synthetic fiber compounding and spinning lines with twin screw extruders, consistent melt metering and stable pressure directly decide fiber uniformity, yarn strength and final yield. Our China-origin polymer melt gear pump is engineered exactly for this demanding scenario, delivering high-precision, low-pulsation melt conveying and pressurization for PET, PA, PP, PLA and other synthetic fiber extrusion processes. As a positive displacement gear metering pump, this polymer melt pump separates the homogenizing task from the metering task of your twin screw extruder. The twin screw ta
2026-11-06 Why can the melt gear pump efficiently handle high viscosity melt transportation?
The melt gear pump is naturally suitable for high viscosity working conditions, and its core lies in its positive displacement working principle. The enclosed volume cavity formed by gear meshing ensures a constant displacement per revolution, unaffected by changes in medium viscosity. Even if the viscosity increases from 1000 Pa s to 10000 Pa s, as long as the speed is stable, the flow rate will still be accurately output. High viscosity actually helps to reduce melt reflux between gear clearances, improve volumetric efficiency and operational stability. At the same time, it can effectively i

2026-10-31 The application value of melt pump in PP, PET, PVC sheet extrusion
In the extrusion production of PP, PE, PET, PVC, and ABS plastic sheets, many enterprises have long faced common process bottlenecks: the extrusion screw conveyor comes with pulse pulsation, causing continuous fluctuations in die pressure, exceeding the longitudinal and transverse thickness tolerances of the sheet, frequent occurrence of defects such as thick and thin edges, ripples, and warping, and a large amount of raw materials becoming corner waste, making it difficult to release production line capacity. Ordinary extruders rely on screws to build their own conveying pressure, making it d
2026-10-27 How to scientifically select a melt pump?
In the process of polymer extrusion production, many enterprises encounter problems such as melt pressure fluctuations, unstable product size, increased thickness deviation, and high energy consumption. Many people first think of the insufficient performance of the extruder, but in reality, the problem often lies in the mismatch between the melt pump and process parameters. As an important device connecting the extruder and the die, the melt pump not only undertakes the important tasks of stable conveying, precise measurement, and continuous pressurization, but also directly affects the stabil

The PET strap extrusion melt pump is a positive displacement gear metering device specially designed for polyester strapping band extrusion systems. Installed between the extruder and forming die, it is an essential auxiliary unit to stabilize melt delivery and improve finished strap quality for both virgin and recycled PET production lines. Unlike relying only on the extruder screw to push molten PET, the PET strap extrusion melt pump takes over the precise metering task. The extruder mainly undertakes plasticizing and feeding, while the gear pump provides fixed volumetric output. This separa
