Plastic Extrusion Melt Pump for Woven Bag Production Lines

The application of plastic extrusion melt pumps in woven bag production lines mainly benefits from their capabilities in conveying, pressurizing, metering, and stabilizing melt pressure and flow rate. Below is a detailed analysis of the application of plastic extrusion melt pumps in woven bag production lines:

I. Basic Functions of Plastic Extrusion Melt Pumps

Plastic extrusion melt pumps are primarily used for conveying, pressurizing, and metering high-temperature, high-viscosity polymer melts. They can pressurize and stabilize the high-temperature melt from the extruder and deliver it to the extruder die at a stable flow rate, thereby ensuring the quality and stability of the extruded products.

II. Application of Plastic Extrusion Melt Pumps in Woven Bag Production Lines

Raw Material Conveyance: During the production process of woven bags, the melt pump can convert plastic granules into molten plastic fluid and convey it continuously and stably to the extruder, providing sufficient raw material supply for the production of woven bags.

Pressure Stabilization: The melt pump can operate under high pressure and maintain stable pressure output. This helps ensure the stability of the extruder during operation, thereby improving the production efficiency and product quality of woven bags.

Precise Metering: The melt pump has precise metering capabilities, ensuring consistent raw material usage for each batch of woven bags, thereby avoiding raw material waste and product quality fluctuations.

Reduced Energy Consumption: The application of the melt pump helps optimize the energy consumption of the extruder. By stabilizing the pressure and flow rate of the melt, the energy consumption of the extruder can be reduced, thereby lowering production costs.

III. Application Advantages

Reduced Tolerances: The melt pump can continuously pump accurate material flow rates to the extruder die, thereby reducing the tolerances of the extruded products and improving the dimensional accuracy and product quality of woven bags.

Improved Mixing Quality: When combined with a co-rotating twin-screw extruder, the melt pump can undertake pressure-building functions, allowing for sufficient mixing function segments within the limited length of the screws, thereby improving mixing quality and production yield.

Simplified Production Process: During the production process of woven bags, the melt pump can eliminate some unnecessary process steps, such as granulation, thereby simplifying the production process and shortening the production cycle.

In summary, plastic extrusion melt pumps play crucial roles in conveying raw materials, stabilizing pressure, precise metering, increasing production yield, and reducing energy consumption in woven bag production lines. Their application helps improve the production efficiency, product quality, and economic benefits of woven bag production.
