The Right Mold Cavity Pressure Sensor for any Process

Cavity pressure is and remains the process variable in evaluating the injection molding process and the quality of the molding. The right choice of sensor and simple and reliable connection technology are the most important criteria for success. The size of the sensor is often determined by the size of the molding. Kistler offers the right sensor for any dimensions – with front diameters from 1 mm (Type 6183A…) to 6 mm (Type 6152A…), or miniature sensors with side cable outlet Type 6184A…. There are, however, other factors that dictate the choice of sensor. For example, fillers and abrasive materials require sensors with a front coating, which Kistler offers for all standard sensors in the form of abrasion-resistant chromium.

Last not least, the process determines which is the right sensor to choose. In low-pressure processes, such as foam of thermoplastics or polyurethane injection molding, particularly sensitive high-resolution sensors must be employed. Kistler’s special low-pressure-processing sensors Types 6172A…, 6177A… and 6178A… have proven effective in these applications.

In addition to cavity pressure, the combined pressure and temperature sensors Types 6189A… and 6190B… can also measure contact temperature. For optical components and class A surfaces, which must be free from any impression of the sensor on the molding, measuring pins (e.g. Type 9247A...), which are mounted behind the wall of the cavity in the mold, measure the compression strain of the steel caused by the cavity pressure.

In combination with single-wire and multi-channel cabling technology, Kistler offers the widest and most easily managed spectrum of cavity pressure sensors: the right sensor for any process.

Kistler at K 2007

Kistler will present its portfolio of products on Stand 10F04 in Hall 10 at K 2007 (International Trade Fair for Plastics and Rubber), which is to be held in Düsseldorf from 24 to 31 October 2007.

Background – Cavity Pressure Curve

The cavity pressure curve serves as a "fingerprint" of the injection molding process. It is the most significant variable in evaluating the quality of the molding.

As the supplier with the largest and widest range of sensors for all methods of injection molding, simple connection technol-ogy and extremely user-friendly, networkable systems, Kistler is the only manufacturer to offer complete monitoring of injection molding from a single source. The company is the world's leading manufacturer of pressure and temperature sen-sors for use in the plastics processing industry.
