Los siguientes ejemplos demuestran de qué manera nuestros clientes usan con éxito MAGMASOFT ® con el fin de obtener una mejor calidad en la fundición, ahorrar costos y reducir tiempos de desarrollo especialmente en el área de diseño de fundiciones.
Quality up, Costs down
Cold-chamber die casting is the preferred process for high volume production of light alloy castings. Currently, half of the world’s production is manufactured using this technology, while continuous improvements in quality are broadening its application for automotive components.

Analysis of Transmission Case Shrinkage Defects
In a high pressure die casting for a transmission case, a shrinkage defect was revealed after drilling of the boss. Due to the current die design, it was not possible to insert a pin into the die, making drilling of the boss the only option for this casting.

Solving a Weighty Cracking Problem
Wheel weights are used on farm machinery to improve traction, as well as to balance tractors loaded with optional equipment. These gray iron castings didn‘t appear to have any defects after casting and did not show any obvious cracks or discontinuities during machining and painting. However, when the weights were mounted to the wheels, cracks appeared.

Real Prototype – Realistic Casting?
Before start of production, many real castings are required for testing under realistic conditions. As with many of these prototype castings, the aluminum steering knuckle shown here was produced as a sand casting. The failure of the prototype casting in a test run would lead to design changes: heavier cross-sections to better withstand the load.

Engine Blocks Full of Stress
Cast iron engine blocks can be found in more than half of all passenger cars. Their performance and weight are, among other criteria, dependent on their geometry and the casting process, especially defects like porosity and residual stresses.
