Join NADCA's Porosity Management Webinar Series
From the North American Die Casting Association (NADCA) web page.
Part 1 - Understanding Porosity - This webinar develops a qualitative understanding of porosity in terms of the Neutral Thermal Axis (NTA) and how casting shapes and heat flows influence the NTA setting the stage for the next three parts of the series. The NTA is an imaginary surface through the interior of the casting that is the last place to solidify and hence is also the location of the porosity whether gas porosity or shrinkage porosity. Before one can influence porosity, he/she must understand what causes it to be where it is and understand it in terms of those things that the casting designer, die designer and process control technician has control of.

Time: 1pm Central
Part 2 - Casting Design - This webinar describes how the shape of casting features influence the Neutral Thermal Axis (NTA) and hence the location and distribution of porosity. It describes shapes that facilitate placing the porosity where it will not be detrimental to the function of the casting. It shows how the designer can identify the proper location and distribution of the porosity and how to specify the NTA and local porosity requirements so the die designer and process control technician will understand what the casting needs.

Time: 2pm Central
Part 3 - Die Design - This webinar shows how to design the die features and components (i.e. cooling channels, die spray application, inserts, cavity blocks, slides, etc) and make the heat flow calculations for locating and sizing them to impose the heat flows necessary to force the NTA to be positioned within the casting as specified by the product design as described in Part II. It shows how one can create a computer spreadsheet to do the calculations.

Time: 1pm Central
Part 4 - Process Control - This webinar explains how the process must be controlled on a shot-to-shot, hour-to-hour and day-to-day basis to insure that the features in the die (designed as per Part-III) are operated correctly so the porosity in the casting will be where specified by the casting design (as per Part-II). Special attention is given to controlling die temperature and the die casting release spray since traditionally the industry has not controlled these variables well and they are critical to managing porosity.
