Process Troubleshooting by Wilde FEA through Cold Forming Simulation & Die Stress Analysis
03 June 2002
Wilde FEA were asked by a leading manufacturer of fittings to the plumbing and heating industry to perform cold forming simulations and die stress analyses of two similar extrusion processes. The first process was an existing manufacturing operation that ran satisfactorily. The second process was designed to produce a longer workpiece section but in service was experiencing early die failures. It was proposed to use FEA software to investigate the differences in the die stresses generated by the two processes to identify potential reasons for early failure.
