One important characteristic to determine the quality for injection molding production is the pressure inside of the cavity.
The pressure can be detected using pressure sensors that measure either directly or indirectly.
An advantage of the indirect sensors is the positioning in the clamping plate of the mold (ejection side).
There is no need for maintenance or removing the sensors if the mold is disassembled for service.
Therefore, the risk of violating the wires of the sensor is more or less zero. Both, Sensor and wires, are protected by the pressure plate and a stainless steel cover.
