Good Reasons for Cavity Pressure Measurement

Benefits at a glance




Kistler sensors and systems can be used to cut costs in a variety of phases either by speeding up, by optimizing or by automating processes.

Zero defects in large-scale production



During large-scale production, mold cavity pressure is used for continuous monitoring of the quality of the molded parts. If this quality fails to meet (or no longer meets) the required standards, then the parts concerned are separated out automatically from the batch.

Mold trial without mold filling studies




Mold trial or, to be more exact, the acceptance of molded parts for large-scale production, is a time-consuming process for molders. In this phase mold cavity pressure systems enable the process to be analyzed.

Negligible variation with real-time control



Automatic switch-over from injection to holding pressure and cascade control are just two examples of how mold cavity pressure is used to control the process in real time.

Optimum quality, shortest possible cooling and cycle times


One essential element of process optimization is the attempt to define settings for efficient production and a safe processing window.

Efficient process and production analysis



Analysis of cavity pressure data enables the process to be analyzed, the production facilities and their efficiency and process scatter to be evaluated. Cavity pressure also provides opportunities for identifying critical production lines.

Greater flexibility during mold set-up




The use of a reference curve helps to significantly shorten set-up and changeover times prior to production. This reference curve of the cavity pressure is determined during process optimization as soon as the optimum part quality has been achieved.

Documented proof of quality




Mold cavity pressures measured during production serve as a clear reflection of the quality of the molded parts, and can be used for comprehensive process documentation.
