Winterthur, October 2022 – The Type 4004A piezoresistive melt pressure sensor from Kistler opens up a new chapter in the evolution of measurement technology. Thanks to its front diameter of a mere 3 mm, this sensor can be operated directly in injection nozzles and small extruders: it can measure both pressure and temperature in direct contact with the plastic melt. The 4004A is equally ideal for use with hot runner systems in injection molding, and in additive manufacturing.
The plastics processing industry is following a clear trend: intelligent molds, injection molding machines and 3D printers are supplying users with the maximum possible information about the process. As well as enhancing transparency, this allows ongoing optimization of the production process.
