Polyester Extruder Processes
It is used to provide high capacity and high mixing performance in raw material extrusion applications.
General Parts:
Raw material feeding hopper, extruder driven motor, gear reducer box, die, spools and winding coil.
Working Principle:
The raw material is melted from the chamber and taken out of the mold in the desired form at the end with the pressure support in the extruder and drawn in the desired dimensions. The product is drawn under constant temperature to ensure the continuity of the form in a stable state.
What is a Melt Pressure Sensor?
Melt Pressure Sensor is an instrument used to measure the pressure and temperature of melted liquids (optional) in processes where plastic raw materials can reach high temperatures.
Why is a Melt Pressure Sensor Necessary?
Almost all extruders use at least one melt pressure transducer because it is desirable for melt pressure/temperature control to improve the quality of the extrusion process.

Melt Pressure Sensor Applications for Polyester Extruder Processes
Melt Pressure Sensor in Mold / Melt Pressure Control Application
Pre-Filter Melt Pressure Sensor / Melt Pressure Control Application
Post Filter Melt Pressure Sensor / Melt Pressure Control Application
Melt-Gear Pump Pre-Melt Pressure / Melt Pressure Control Sensor Application
Melt-Gear Pump Post Melt Pressure Sensor / Melt Pressure Control Application
Chip Cutters Melt Pressure Sensor / Melt Pressure Control Application
Aim:
*Checking the melt pressure, flow stability,
* To ensure the formation of the necessary pressure for production,
*Monitoring for possible contamination that could clog the filter changer and cause pressure drop in the mold, and as a result to determine if clogged filters need to be replaced (therefore the pressure is measured before and after the screen changer)
*The gear pump is used to give a constant flow rate to the mold: the flow is adjusted based on the measured pressure value (the pressure value is used to give feedback to the driver for screw speed adjustment)
*Creating necessary prescriptions for production,
* Evaluation of plastic raw materials,
*Controlling Pressure,
*Preventing excessive pressure on the screw,
* Protecting screw wear,
