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.

About: Kistler Instruments
Kistler is one of the world's leading suppliers of measurement technology. Kistler pressure sensors, force sensors and accelerometers use the piezoelectric effect for precise measurement of mechanical properties. Kistler is a privately-owned Swiss company which develops and manufactures sensors and electronics for measuring pressure, force and acceleration. Additionally, the functionality of electronics plays an increasing role when defining a measuring system and even more frequently, electronics in fact becomes part of the sensor itself. Most of Kistler's products have been developed in close cooperation between leading universities or research facilities and Kistler's engineers. Investments in Kistler's research department have led to the development of new crystals which enable reliable measurements to be taken under the most extreme environmental conditions. The results of our in-depth crystal research will give us a leading edge in advancing the state-of-the-art. |
