Kistler Instruments Ltd. - PRODUCT NEWS
One hundred and twelve pressure sensors in a single mould.
Is this a world record?
One hundred and twelve is the number of Kistler (www.kistler.com) pressure sensors fitted to the moulds for the injection moulding of insulin pen components; one each to the 96 cavities and 16 manifolds. The aim is to use cavity pressure monitoring to achieve zero defect production automatically and reliably.
With a front diameter of only 1 mm, the Kistler Type 6183A pressure sensors are the smallest ever used for cavity pressure monitoring. The mould maker adapts the front ends of the sensors to the contours of the cavity wall, using erosion technology to fit both the sensors and the mould inserts. The fitting of such a large number of sensors to a single, complex mould was made possible by using Kistler's single-wire technology. This cut-and-grip technique permits the sensor cables to be fitted and removed quickly and easily without any additional tooling.
Specially developed high channel, charge amplifiers transmit the measurement data digitally to the Dataflow process analysis system, which offers functions for the visualization, monitoring and documentation of injection moulding processes based on the cavity pressure curve. As with other Kistler systems, Dataflow monitors changes in cavity pressure in all cavities cycle by cycle. Parts that are identified as defective or non-conforming are automatically rejected.
