This decision for a system supplier was well-considered and based on a detailed evaluation process in advance. Heunisch was already using older Kurtz low-pressure casting machines, which, however, were no longer state of the art.
With the new casting line concept including the integrated furnace management system and shuttle, the company with headquarters in Bad Windsheim and further locations in Steinach (Thuringia), Krásná and Brno (both Czech Republic) has laid the foundation for good castings. The complete concept of the casting line with high flexibility, fastest furnace change and best melt quality as well as easy expansion of the production capacity convinced Heunisch.
Long casting without changing the furnace again
The large crucible furnace with a capacity of 2.8 t allows both: long continuous casting without changing the furnace again and extremely high flexibility for positioning the riser tubes at the same time. Whether multiple cavities or large structural components - the large furnace allows the riser tubes to be positioned exactly where they are needed.
The concept with the shuttle also allows the downtime of the machine to be reduced to a minimum, which benefits OEE. The furnace is prepared outside the machine with the best melt quality, and the actual changeover is realized in the machine´s off-time - true to the motto "the machine has to run to make money".
To further increase efficiency, the casting machine has two mould change systems so that a new mould can be prepared on one and the old one dismantled in parallel on the other. The cooling system is connected via multi-couplings, which saves time and also means error-proofing when connecting the numerous cooling systems.
Complete casting solution from a single source
In combination with the latest machine innovations, such as the cooling technology developed in-house by Kurtz, the best mechanical properties are achieved and the cycle time is significantly reduced. Thanks to the highly precise pressure control, low-turbulence mould filling is implemented, producing castings of the highest quality standards. Heunisch wanted much more than just the best machine technology - the company wanted a complete solution from melt preparation to handling and casting from a single source. In the end, the entire Kurtz know-how with the complete solution for the new casting line and the years of good cooperation convinced Heunisch all along the line.
The Kurtz team would like to express their sincere thanks for the confidence placed in them and the great cooperation and is already looking forward to future projects!
