Pressure Stabilization & Flow Control
The melt pump eliminates pressure fluctuations from the extruder through gear-driven forced conveying, ensuring PA/PP melts enter the co-extrusion die head at a constant pressure and flow rate.
Example: In PA66 automotive oil pipe production, pressure stability is critical to prevent wall thickness variations. The pump reduces pressure errors to ±0.5%, lowering defect rates.
Enhanced Mixing Uniformity
For high-viscosity PA/PP melts (e.g., glass-fiber-reinforced grades), the pump performs secondary homogenization, reducing interface delamination risks in double-layer structures.
Energy Efficiency & Productivity Gains
By reducing extruder backpressure by 30–50%, the pump cuts energy consumption by 15%+ while boosting output.
Case Study: A PA6 tube line achieved a 40% output increase after pump installation, attributed to stable pressure enabling higher traction speeds.
For PA/PP nylon rope double-layer co-extrusion, select melt pumps with high-temperature resistance, GF-compatible materials, and precise pressure/flow control.
