Fundamentals of Measurement Technology

Fundamentals of mold cavity pressure measurement


The cavity pressure within an injection mold provides very precise information about the filling phase, the compression phase and the holding pressure phase. Gaining an insight into physical correlations facilitates the analysis and interpretation of the cavity pressure curve.

Zero-Defect production




The cavity pressure in an injection mold is the process parameter that correlates directly with the qualities of the molded part. The cavity pressure can therefore be used directly to monitor production and quality.

Fundamentals of contact temperature measurement


The melt contact temperature can be measured in addition to the mold cavity pressure. This is done using either separate temperature sensors or combined pressure/temperature sensors.

Typical system for zero-defect production



A typical system for monitoring the quality of a technical component, for example a connector for the electrical industry, consists of one mold cavity pressure sensor (such as the 1 mm Type 6183A... sensor) in each cavity.
