Case Study

Kistler Inserts

Sprint Tool and Die, a British toolmaking company, involved in cutting edge technology to automatically link cavity pressure monitoring with hot runner controller.

Telford based Sprint Tool and Die are working with Kistler Instruments and Polymer Training and Innovation Centre, to install Kistlers latest transducer technology  to automatically balance hot runners and eliminate the need for manual optimisation. The Kistler CoMo software communicates with the Mold Masters hot runner controller, so as to achieve constant pressure within each moulding.

Cavity Pressure Monitoring is a well established practice, in terms of putting sensors in a mould tool and using a monitoring system to plot the pressure in each cavity.

But the new technology will not only communicate with the hot runner controller, but it will make necessary adjustments and balances automatically. 

Not the first research project that Sprint Tool and Die have become involved with. The Emold project, in which Ian Amos, MD, Sprint Tool and Die, was a research partner, investigated the possible of  progressing this information  to the next level, so that hot runner systems and controllers could be accessed remotely – from another room, country or continent.
