In order to achieve optimally resource-saving production and to minimize scrap, viscosity fluctuations must be detected and any required counteraction taken as early as possible. Viscosity fluctuations may be caused, for example, by differences in fiber content due to batch change, or by variations in granulate quality. With the latest version of its HiQ Melt application, WITTMANN BATTENFELD has created a means to reveal deviations already at the metering point.
When it comes to application technology, machine setters today receive ample support from appropriate software packages. This starts with Quick Setup, already installed by WITTMANN BATTENFELD for a number of years as a standard component of the Unilog control system generations B8X and B8. This tool calculates a parameter setting proposal with process data based on just a few original data, for subsequent acceptance and confirmation. Viscosity fluctuations are then compensated during ongoing production by the already well-known HiQ Flow Premium program, but these fluctuations can also be checked by the two applications HiQ Melt Monitoring and HiQ Melt Premium.
