Die life is critical to profitability of die casting operations. Operating variables such as pre-heating and die lubricant application can make a big difference in die life. Preventive treatments such as stress relief and periodic application of shot-peening are available to preserve die life. When eventually a die is in need of welding repair, using best welding practices can further extend the useful life of a die. Professor David Schwam, Case Western Reserve University, will address methods of die care and maintenance from the perspective of best approaches to preserve and extend die life in this webinar series.
Part 1
Why Dies Fail and How to Prevent Failures - This webinar will provide a concise overview of factors that play a role in failure of dies from cradle to grave. Understanding the failure mechanisms is important not only in the design and fabrication but also in the maintenance and care of the dies. Thermal fatigue is the main mode of failure in aluminum die casting dies. It is sensitive to imperfections in the surface of the dies, and therefore depends on good die maintenance practices. Cleaning and polishing practices will be covered. Soldering and washout are often causing downtime and require replacement of cores. Care of the die surface and proper die lubricant application can prevent costly downtime. It will also address methods of combating these failure modes.

Part 2
The Effect of Softening, Residual Stresses and Stress Concentration Factors on Die Life - This webinar will discuss in detail the effect of stress concentration factors, softening and residual stresses in thermal fatigue, soldering and washout failures. While eliminating tensile residual stresses may be difficult, minimizing them can help in preventing costly failures. Softening is evolving especially in the hottest spots of the die and can lead to premature failures. It will also address the commercially available preventive treatments such as stress relief and periodic application of shot-peening.

Part 3
Repair of Dies - Over time, even the best die will show some cracking. This webinar will address how using best welding practices can go a long way in extending the useful life of welded dies. Pre-heating and post heat treating methods will be covered. In addition we will present novel methods of laser micro-welding cracks during this webinar.
