Where should the melt metering pump be installed on the extru

The melt metering pump should typically be installed on the extruder between the twin-screw extruder and the die. This placement allows the melt metering pump to play a crucial role in the plastic processing operation. By positioning it here, the pump can effectively control and meter the flow of molten plastic material, ensuring consistent and accurate output.

Moreover, it's important to monitor the melt metering pump during operation, including parameters such as outlet pressure, suction pressure, pressure difference between inlet and outlet, motor current, seal of the gear shaft, and pump temperature. This ensures the pump operates normally and contributes to the overall efficiency and quality of the extrusion process.

In summary, the melt metering pump should be installed between the extruder and the die, with appropriate monitoring measures in place to maintain optimal performance.
