Making Steel Castings
Introduction
Introduction to the topic and panelists.
16 minutes 58 seconds recorded on February 6 2024
Simulation Limitations
Limitations of simulation and why it is important to look at a casting as a whole as all of the steel that goes into a mold (part cavity and rigging) will be affected by the directional solidification of the steel. This topic also stressed three other key items: the effects of variation, reality v. modeling (get out to the shop floor and get data), and “making steel castings” is much more beyond just rigging with many factors playing into the total cost of a casting.
40 minutes 8 seconds recorded on February 9 2024
Rigging Basics
Rigging basics – what is rigging, its history and terminology with focus on sand casting. This topic also discusses how rigging and mold features (vents, draft, risers) apply to and affect making good steel castings along with some founders’ tricks for doing things such as promoting feeding from a riser.
35 minutes 39 seconds recorded on March 4 2024
Casting Engineering
Casting engineering - who is it, what this is and what you need to know. This topic also reinforces the benefits of being out on the shop floor.
