The Module Procedure of Sand Casting Metal

Exercise may be a reflection, alone, or in groups. If used in the production of several pieces of cast metal, including examples of pre-cut should be used and students are encouraged to participate by visual inspection of the samples to the differences and imperfections determine, along with projections for how would that affect material properties defects.The no overall make up, concepts and fundamental analysis are discussed in more detail in a PowerPoint presentation.

1.Display series of samples cast on a hard surface and discuss the importance of casting sand and the various factors involved.

2. Display similar examples were pre-cut. Ask students if they can find any flaws in the sample (s) and if they can predict if the material defects internally and how they would go about finding out. Discuss hardness materials inorder to expand the concept. (Would the hardness of materials on this website module mated a great addition to help in teaching this concept.)

3. Show a PowerPoint presentation and discuss each slide.

a. Slide 1-2: Start sand casting (key)

b. Slide 3-9: Typical equipment and supplies

c. Slide 10-12: Experimental Set-up

d. Slide 13: Parts sand cast

e. External and Internal Flaws: Slide14

f. Slide 15: Safety Guidelines and importance of safety

g. Slide 16-18: Questions, recap, the basic terms

4. If a rally used to be sure to show the students examples of materials consumed sand. If identical samples available, ask students if they mention any differences and make predictions of the internal voids are present. To get samples or cut in half, or in sections to prepare. Show will half / sectioned sample pieces for the students as to allow them to see that sometimes imperfections in materials that do not appear on the surface.If lab, have students (individually or in groups) to up their models using the same model for all equipment mold.If provide complete laboratory experiment can be carried out through the steps provided.
