Product Information
CoMo Injection Hot Runner Balancing
Product Name CoMo Injection Hot Runner Balancing
Description Cycle by cycle, CoMo Injection with MultiFlow monitors the pressure profile of each cavity of a hot-runner mould from injection, through compression and holding, to the cooling phase. During the injection and holding pressure phases, the MultiFlow software analyses the pressures curves in all cavities. The synchronous rise in pressure in all cavities is achieved by the system automatically calculating the optimal set-point temperature for each hot runner tip, which is then transferred via an interface to the hot runner controller.
The mould is automatically balanced during process start-up, and continuous optimisation keeps it stable during production. The balanced mould always exhibits congruent cavity pressure curves during the injection and holding pressure phases. At the same time, CoMo Injection continuously monitors the quality of all of the parts produced and signals any need for automatic separation of rejects.
Hot-runner balancing with MultiFlow completely eliminates the need for time-consuming manual optimisation and adjustment of the hot-runner temperatures during set-up and production.

CoMo Management Information System
Product Name CoMo Management Information System
Description The CoMo MIS Management Information System (MIS), widely used by the injection moulding industry for optimizing quality and productivity by minimising rejects, is now available with a completely new user interface similar to the CoMo Injection process monitoring and control system. The new interface is clearly laid out and logically structured making the system exceptionally intuitive and easy to use.
Most of the functions are now cursor controlled to simplify process analysis. A new feature is the ability to import and export pressure curves to allow comparison of the current process with processes on other machines or sites and importing of data from simulation programs, etc. In addition to production data of current processes, a browser can be used to access and retrieve information about completed orders and batches from the database for inclusion in analyses and comparisons.

Existing CoMo MIS systems can be upgraded to the new interface simply and economically.

New generation melt pressure measuring chain is precise and reliable
Product Name New generation melt pressure measuring chain is precise and reliable
Description When moulding components to very tight dimensional tolerances the precise measurement and recording of melt pressure is essential to ensure minimum out of spec product. The new melt pressure measuring chain from Kistler brings new precision and repeatability to measuring this important process parameter directly in front of the screw. The new measuring chain is made up of a factory calibrated sensor, matched amplifier and cable designed specifically to measure and record the melt pressure in injection moulding machines and hot runner systems and is also suitable for measuring static pressure in polymer pumps.
The new sensor allows the melt pressure and temperature signals to be integrated into the moulding machine's control system providing a practical, cost effective means of enhancing production efficiency.
The very stable, high temperature resistant, piezoresistive measuring element is protected by a robust diaphragm allowing the sensor to be mounted directly in the flow of the material to eliminate the time lag inherent in indirect measuring systems. A temperature signal derived from the piezorestive element is used by the amplifier to compensate for temperature variations providing an exceptional level of accuracy of the melt pressure in real time.
