What is shrinkage casting defects ?

How do you correct your melt in order to control stability ? What is shrinkage casting defects potential in the melt ? In this article, we’re not referring to gating design, casting geometry or casting procedures. Today, let’s discuss the metallurgical shrinkage tendency of the melt itself. David Sparkman at MeltLab presented this theory at the Ductile Iron Society last October 2015.

Pre-Launching the SF Casting defects app on your mobile phone !

trois screenshotsDo you carry your mobile phone on the foundry floor? Then, why not use it for more consistent castings ? Let us present to you why our new casting defects app will become a must-have in 2016-2017. We’re very excited to be the first using it here in Québec. www.castingdefect.com

*** March 30th update : Please e-mail François Audet ( click ) if you want to contribute to the app with your casting defect pictures.  Free version available at www.castingdefect.com*** Continue reading “Pre-Launching the SF Casting defects app on your mobile phone !”

Were you at the University Laval event on the physics of Thermal Analysis?

Équipe MetSoc- Sparkman et SFLast thursday January 28th, MetSoc student chapter at University Laval hosted this memorable beer and pizza event on the physics of thermal analysis, which was lectured by David Sparkman ( MeltLab).  Can you tell what the gentleman on the left is holding on the photo? No, it’s not a beer funnel. Continue reading “Were you at the University Laval event on the physics of Thermal Analysis?”
