Casting
Module
Outcomes
1. Be able to analyze casting
processes based on scientific principles, engineering challenges, and
engineering practice.
2. Be able to determine appropriate
casting processes for applications by justifying the selection as compared to
alternatives.
Preparation

The
following Sections from the text: Chapter 10 with the exception of 10.2.3 –
Analysis of Pouring. Note that we will use SI Units and that the example
problems do not fully meet the standards of this course as units are not included
in the calculations. A comparison of Figures 10.5 and 10.6 showing the cooling
curves for pure metals and alloys is key. Figure 10.8 is one of the best
illustrations of Shrinkage I have seen. Sections 11.4-11.7 should be connected
to the relevant parts of Chapter 10 where possible. Review the sections on Sand
Casting, Investment Casting, Lost Foam Casting, Permanent Mold Casting and Die
Casting.

The
following Wikipedia Articles were reviewed on 1/11/15. The article on Casting in
General provides a good overview of the casting process. The chart which
compares the different casting processes is great. If you can refer to it as
you take notes from Sections 1 and 2 I think you will learn a lot. Also please
pay careful attention to Section 4. I do not like the work theory as the
section better reflects the relevant scientific principles, engineering
challenges, and engineering practices. We will focus on the following casting
processes: Sand Casting
Investment (Lost Wax)
Casting Lost Foam
/ Evaporative Pattern Casting Permanent Mold
Casting, and Die Casting
. The images provided in these article are excellent especially when combined
with the processes descriptions. As you read each of these compare what you
discover to the casting process in general and also focus on how each process
accomplishes what is necessary to make a part through casting. The goal of this
is to be able to compare (similarities and differences) of the various casting
processes. So that you can make decisions as to which casting process would be
best for a given application.
ð
The
following videos from the text provide great examples of: Sand
Casting, Investment
Casting, and Foam
Casting. As you view these I suggest you elaborate on the notes you took
from the reading.
ð
The
Casting Experiences Provided for Freshmen at
Kettering. Focus not only on how the processes relate to casting in general,
but on the details of the procedures. You may want to compare these to your
notes from the reading and the videos. You may want to refer to these later in
the course when ISO and Safety are discussed.
