Core and Mold

Knowledge Counts! Core and Mold Simulation

Improvements are only possible when you systematically implement knowledge of the metal casting process. Simulation software from MAGMA is based not only on physics and mathematics, but also integrates a comprehensive database of knowledge. No information regarding a simulation project is ever lost – all results are quickly and easily accessible to by your employees for years to come.

 


The quality of the cores and molds plays a significant role in the resulting casting quality. With increasing casting complexity, the production of cores and molds becomes a determining factor for casting manufacturing. Therefore MAGMA also offers software for core and mold production. MAGMA C+M is also available as a stand-alone application, independent of MAGMA5.

 

MAGMA C+M 

 

MAGMA C+M is available as a stand-alone core simulation software or as a functionally equivalent add-on module for MAGMA5.

 

As a powerful simulation tool, MAGMA C+M turns core production into a calculable and optimizable activity. Core shooting, core curing and the thermal control of core boxes can be analyzed to find the best solution.
