What are the reasons for installing a melt pump on an extruder?
The primary purpose of installing a melt pump on an extruder is to optimize melt transportation and processing, addressing the limitations of the extruder itself in high-viscosity and high-precision processing. The specific reasons are as follows:
Stabilizing flow rate and pressure
The screw of an extruder is influenced by factors such as raw material characteristics (e.g., viscosity, impurities) and temperature fluctuations, leading to fluctuations in melt flow rate and pressure. This can result in uneven thickness and unstable dimensions in finished products (e.g., films, pipes).
As a positive displacement pump, the melt pump can precisely control melt flow rate, significantly reducing flow fluctuations (typically within ±1%), ensuring stable pressure, and improving product consistency.
Improved Extrusion Efficiency
The melt pump provides stable pressure for the melt, reducing the pressure load on the screw, allowing the screw to focus more on raw material plasticization and mixing, thereby increasing the extrusion volume per unit time. This is particularly suitable for high-viscosity, high-resistance processing scenarios (such as PC, PET, etc.).
Optimize material plasticization quality
By forcing melt conveyance, the pump reduces melt residence time in the barrel, lowering the risk of material degradation caused by high temperatures. Additionally, the shear action of the pump's gears further mixes the melt, improving material uniformity.
Adapting to complex processing requirements
In processes such as blending and composite extrusion, multiple extruders must precisely control the proportions of each component. The melt pump can achieve proportional delivery of different melts through precise metering, ensuring formulation stability.
Additionally, the melt pump can be used in conjunction with screen changers and other equipment to maintain stable flow during impurity filtration, avoiding the impact of screen changing on product quality.
In summary, melt pumps significantly enhance the processing precision, efficiency, and product quality of extruders, making them indispensable key equipment in high-end plastic processing applications such as precision tubing, films, and synthetic fibers.
