Application of high temperature melt pressure sensor in plastic machinery
In the extrusion production line, high temperature melt pressure sensors 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 make it fully play its role.
In the extrusion production process, some quality standards of the product (such as dimensional accuracy or surface smoothness of parts with mineral fillers, etc.) require optimal control of the extrusion pressure, and the high temperature melt pressure sensor is to achieve this requirement important components. By installing a melt pressure sensor and a pressure control device at the connection of the mold inlet, the production rate can be made more stable and the waste of materials can be reduced at the same time. Melt pressure sensors play an important role in improving melt quality, improving production safety, protecting production equipment and prolonging their service life.
In addition, measuring the pressure through the filter screen and the melt pump is also very important to ensure the safety of production and optimize the performance of the equipment. If the melt flow into the mold is blocked, a sensor under the screen will send out an alarm to alert the operator. When a sensor upstream of the screen sounds an alarm, it is an indication that the extruder internal pressure is too high, possibly causing excessive wear on the screw. For manufacturers using melt pumps, it is necessary to measure the inlet and outlet pressures of the melt to ensure that the melt can flow continuously into the mold, because any obstruction may cause damage to the melt pump.
