To provide complete control of blow molding processes, we offer several control concepts customized for our extruder and extrusion head systems.
We deliver fully equipped electrical cabinets, including control panels, adding to the functions of an existing machine control system. Our MERC (Müller Extrusion Retrofit Control) is available for new blow molding machines and as a retrofit of existing equipment. The MERC provides easy-to use, self-explanatory operator guidance and assures complete control at all times.
The MERC was designed especially for multilayer retrofits and provides control of all key extrusion functions. Thanks to its 15-21” TFT screen, all required process data can be viewed simultaneously. Again, a highlight of the MERC system is its ability to display 3D graphics of the extrusion head and the extruders simplifying even the operation of complex retrofit solutions.
With its high-quality, intuitive user interface, the MERC lends itself not only to retrofits, but is also supplied as an addition to the control systems of new machines if a clear separation between extrusion and machine functions is desired.
As the name suggests, the miniMERC is a MERC system with fewer features for simpler retrofits. The miniMERC system consists of a 7” touch screen PC in a mobile enclosure, which still provides all basic functions required for the extrusion. A highlight of the miniMERC are screen pages with 3D graphics, matching exactly the extrusion head and the extruders being controlled. This simplifies operation considerably.
Using its wall thickness control (WTC) capabilities, the miniMERC can also serve as a compact and cost-effective retrofit, replacing any outdated rack-style parison programmer.
