Manufacturing Technology – II MI 232 Instructor – Inderdeep Singh Spring 2011-2012 Foundry - Factory that produces metal castings • Casting: Process in which molten metal flows by gravity or other force into a mold where it solidifies in the shape of the mold cavity Steps: 1. Melt the material (metal) 2. Pour it into a mold 3. Let it freeze Refractory mold pour liquid metal solidify‚ remove finish Capabilities and Advantages • Versatile: complex geometry‚ internal cavities

of sparta a heroic king‚ the Author is Helena P. it’s about how king Leonidas led the 300 Spartans to war and how they train their sons to be strong and become a Spartan. From the moment of a Spartan girl or a boy came into the world‚ the military and the city state were the center of every Spartan citizen’s life.

What is meant by casting shadows instead of light? Give an example of someone you have observed and their behavior that "cast shadows". (It could be someone in Politics‚ at work‚ or even in your family. (Just remember that other students will read your post) What do you think were the effects of the shadow they cast? Casting shadows focuses on leaders who project shadows of their inner darkness. A person who this student has observed casting shadows in their behavior is a previous general manager

Introduction A sand casting or a sand molded casting is a cast part produced by forming a mold from a sand mixture and pouring molten liquid metal into the cavity in the mold. The mold is then cooled until the metal has solidified. In the last stage the casting is separated from the mold. There are six steps in this process: (see sketch below): 1. Place a pattern in sand to create a mold. 2. Incorporate a gating system. 3. Remove the pattern. 4. Fill the mold cavity with molten metal

1.0 Calculations 1.1 Sizing of component (including Shrinkage allowance) When cooling from molten state‚ all metals decrease in volume. When cold‚ casting will be smaller than their pattern. In order for parts to be of correct size‚ patterns are made larger to allow shrinkage. The extra size is called Shrinkage Allowance. Different metals have different Shrinkage Allowances. For the purpose of our project‚ we have been using Brass having shrinkage allowance of 1.5%. Length Nominal

Casting Defects: Some defects are common to any and all process. These defects are illustrated in figure briefly described in the following: [pic] A) Misruns: A Misrun is a casting that has solidified before completely filling the mold cavity. Typical causes include 1) Fluidity of the molten metal is insufficient‚ 2) Pouring Temperature is too low‚ 3) Pouring is done too slowly and/or 4) Cross section of the mold cavity is too thin. b) Cold Shut: A cold shut occurs when two portion

Spanish Tragedy Thomas Kyd Context Born in 1558‚ Thomas Kyd began life with a series of good omens. He was the son of a prosperous middle-class family; his father‚ Francis Kyd‚ was a scrivener—a type of scribe that was very important in the complex world of Elizabethan law. When he was seven‚ Thomas began to attend the Merchant Taylors school‚ a new and modern school for boys. Admission to Merchant Taylors required a significant knowledge of either Latin or Greek as well as the Bible‚ so Thomas’s

Q. Do you think Kappmeyer should sign the proposal? Why or why not? Ans. I think Kappmeyer should not sign the proposal. My recommendation is based on understanding the basic nature of disruptive technologies‚ and their future impact on the steel industry. Kappmeyer is currently making the decision based on short-term gains. With this proposal USX will have 2.6M ton capacity which 3 times greater than Nucor’s 0.8 M ton but the conventional method is not sustainable on a long term basis. CSP

Superior Spartan Oligarchy Superiority is defined as being of higher grade or quality. And while the Athenian democracy has been able to become somewhat of a staple in modern society‚ in its time‚ it was the Spartan’s oligarchic system that allowed them to create such a strong society. It was a society that thrived on its strong political system based around a strong military. It is undeniable that in the time in which they both existed‚ the Spartan Oligarchy was superior to the Athenian
