MAGMA stands for robust and innovative casting solutions as well as a strong partnership with the metal casting industry. MAGMA’s product portfolio based on Autonomous Engineering™ leads to robust and cost effective solutions in component design, tooling lay-out and production.. The application of the MAGMA APPROACH, combined with MAGMA’s comprehensive commitment to customer support. A potential supplier can now offer simulation output as evidence that the proposed die design is feasible and then gives assurance of anticipated satisfactory delivery. One of the approaches made by Biswas concerned the development of a modular sequential simulation computer method for axisymmetric forging. The method divides the forging into.
The present study attempts to predict the forging load and stresses through relatively basic analytical methods. Using the example of an axisymmetric forging, consisting of a flange and a shaft, the slab or Sachs method has been applied to develop a computer-simulation technique. The forging process is analyzed in small steps of deformation. Simulation of manufacturing processes is commonly referred to as “process simulation” or “virtual manufacturing.” It includes the simulation of forming, stamping, machining and other processes to determine the manufacturability of the design, as well as the effect of design changes upon the manufacturing method.
Forging Manufacturing Design Considerations:For parts manufactured by forging that are produced in two-part impression dies, the designer should take into account the following: the parting line, the draft, the presence of ribs, bosses, webs, and recesses, and . A typical open-die forging process is shown in Figure 1. Simulation of the Open-Die Forging Process. The goal of every open-die forger is to maximize throughput and achieve the highest material yield possible while producing the highest quality material properties.

The aim of this engineering thesis was to design and simulate a die for a rectangular pro-file. The project consisted of studying melt flow characteristics of plastics and how the die structure should be set in order to get the desired shape.
After the die has been de-signed on 3D Solid edge design software it was simulated on COMSL flow simulation.
