Melt pressure sensor in the installation and maintenance of plastic machinery

In the extrusion production line , high-temperature melt pressure sensor to improve melt quality, improve production safety and protection equipment and other aspects play an important role. Meanwhile, melt pressure sensor is very sensitive element , only the proper installation and maintenance in order to make the role into full play .
In the extrusion process, the product of the number of quality criteria ( such as the dimensional accuracy of the surface flatness or added parts of mineral fillers , etc. ) are required to optimize the extrusion pressure control melt pressure sensors are required to achieve this important components. By setting the melt pressure sensor and pressure control means connected to the inlet of the mold , the yield can be more stable , with less waste material. Melt pressure sensor to improve melt quality, improve security and to protect and extend the life of production equipment and other aspects of production plays an important role.
Further , the measurement through a pressure filter and the melt pump to ensure safety and to optimize the production performance of the device is also very important. If the melt flows into the mold blocked filter below the sensor will alert prompts the operator. When an alarm sensor upstream of the filter , indicating that the internal pressure is too high extruder , the screw may be excessive wear. For applications melt pump manufacturers, the need to measure the inlet pressure and the outlet pressure of the melt to ensure that the melt can continuously flow into the mold , since any impediment may cause damage to the melt pump .
In the extrusion line melt pressure sensor assembly can only measure a single point pressure sensor can also be used to measure the number of line sensors. Melt pressure sensor and data logger, voice alarm device connected to the use of process control system can adjust the process parameters of the extruder . Meanwhile, the pressure sensor is very sensitive element , if it is not properly installed and maintained , it is very easy to damage . Here are a few simple way to help extend the life of the pressure sensor , and can help users get accurate and reliable measurement results.
