The important role of Melt Pressure Transducer in extrusion lines

Melt pressure transducer for extrusion lines

In the extrusion line, melt pressure transducers play an important role in improving melt quality, improving production safety and protecting production equipment. At the same time, the high-temperature melt pressure sensor is a very sensitive component, and only proper installation and maintenance can fully play its role.

In the extrusion process, some quality standards of the product (such as dimensional accuracy or surface flatness of mineral filler parts) require optimal control of the extrusion pressure. High temperature melt pressure sensors fulfill these requirement important components. By providing a melt pressure sensor and a pressure control device at the mold inlet connection, the yield can be made more stable while reducing material waste. Melt pressure sensors play an important role in improving melt quality, increasing production safety, and protecting production equipment and extending its service life.

In addition, measuring the pressure through the filter and the melt pump is also important to ensure production safety and to optimize the performance of the equipment. If the melt is blocked while flowing into the mold, the sensor under the filter will alert you to the operator. When the sensor on the filter screen gives an alarm, it indicates that the internal pressure of the extruder is too high, which cause excessive may wear on the screw. For manufacturers applying melt pumps, it is necessary to measure the inlet and outlet pressures of the melt to ensure that the melt can continuously flow into the mold, as any impediment can cause damage to the melt pump.

The high temperature melt pressure sensor assembled on the extrusion line can be a single sensor that measures only one point pressure, or a series of sensors that measure the entire production line. The melt pressure sensor is connected to the data logger and the audible alarm device, and the processing parameters of the extruder can be adjusted by the processing control system.
