Cavity Pressure Sensors Ideal for Monitoring During Injection Molding Process

摘要

Meusburger offers sensors for cavity pressure measurement, which includes two types for direct and indirect measurement. Cavity pressure sensors make it possible to convert the pressure in the cavity to a measurable charge. The sensors are equipped with high-precision quartz crystals, which release a charge under the influence of pressure or force. This charge, amplified by a charge amplifier, provides precise information about the pressure applied to the sensor and makes it possible to monitor the exact cavity pressure in the injection molding process. The ideal installation position in the mold depends on the application. For example, for general monitoring and process optimization, the sensor is placed as close as possible to the sprue or on a thicker section of the molded part. Other typical applications are strength monitoring and monitoring or controlling viscosity, compression or shrinkage.
