Preventing Mold Clogging with Melt Pressure Sensors
Mold blockages are one of the most common problems in the plastics and polymer industries. These situations lead to serious production stoppages, cost losses, and product waste. This is where melt pressure sensors play a critical role.
Symptoms of Mold Blockage
Fluctuations on the product surface
Sudden increases in line pressure
Stress in pumps and motors
Irregular melt flow
These symptoms are often noticed late. However, using pressure sensors allows for real-time monitoring of line pressure, allowing for early detection of problems.
How Do Sensors Work?
Melt pressure sensors, located at the mold inlet, continuously monitor the pressure. If a higher-than-normal value is detected, the system automatically:
Reduces pump speed
Sends an alarm to the operator
Safely stops the line if necessary.
This protects the machine and ensures production quality.
Advantages of an Early Warning System
Reduces waste rates
Optimizes energy consumption
Prevents unplanned downtime
Production safety is increased.
Melt pressure sensors are not only a measurement tool, they are also a safety mechanism for the production line. Preventing mold blockages becomes much easier with the high-precision pressure sensor solutions offered by MeltSensor.
