Nylon Double-Layer Co-Extruded Melt Pump

In nylon double-layer supply production lines, the melt pump is the core component ensuring the stability of the extrusion process and product quality. Its primary functions include:

1. Precise pressure control and turbulence elimination: By forcibly conveying the melt through gear meshing, it eliminates pressure fluctuations in the extruder, ensuring that the nylon melt enters the supply die head at a constant pressure and flow rate, thereby preventing layering or uneven thickness.

2. Enhancing mixing uniformity, performing secondary purification on high-viscosity nylon melt, particularly suitable for modified materials containing glass fiber or flame retardants, reducing the risk of interface layering.

3. Energy saving and efficiency improvement, reducing extruder load while increasing output. As a pressure stabilizer for supply molding, the melt pump directly determines the bond strength and dimensional accuracy of dual-layer supply products, making it a critical piece of equipment for ensuring efficient production.
