Contact Free Mold Cavity Pressure Measurement

With the measuring pin sensors Type 9243B..., 9245B... and 9247A..., Kistler now offers the ideal solution for measuring the cavity pressure for parts with very stringent optical and finish requirements. These sensors are placed behind the wall of the cavity in the mold structure or in the die, where they measure the compression strain of the steel induced by the cavity pressure. This mounting location away from the surface of the cavity also avoids influencing the temperature field near the surface of the mold.

Measurement of cavity pressure for injection molded optical parts such as lenses or light guides, and moldings with class A finishes for the automotive industry, was just not possible in the past. Their surfaces must be free of any marks from sensors, measuring pins or ejectors.
