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

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 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

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

8/28/2011 Sand casting Metal Casting M t l C ti By S K Mondal Compiled by: S K Mondal Made Easy Sand casting uses ordinary sand as the primary mould material. The sand grains are mixed with small amounts of other materials‚ such as clay and water‚ to improve strength‚ mouldability and cohesive strength and are then packed around a pattern that has the shape of the desired casting. The pattern must be removed before pouring‚ the mold is usually made in two or

The Metal Casting or just Casting process may be divided into two groups: Hot Forming Process Examples are Centrifugal casting‚ Extrusion‚ Forging‚ Full mold casting‚ Investment casting‚ Permanent or Gravity Die casting‚ Plaster mold casting‚ Sand Casting‚ Shell Mold casting. The method to be used depends upon the nature of the products to be cast. Cold Forming Process Examples are Squeeze casting‚ Pressure die casting‚ Gravity die casting‚ Burnishing‚ Coining‚ Cold forging‚ Hubbing‚ Impact

Crown cork The crown cork (also known as a crown seal‚ crown cap or just a cap)‚ the first form of bottle cap‚ was invented by William Painter in 1892 in Baltimore. The company making it was originally called the Bottle Seal Company‚ but it changed its name with the almost immediate success of the crown cork to the Crown Cork and Seal Company. It still informally goes by that name‚ but is officially Crown Holdings. Crown corks are similar to the Pilfer proof caps‚ as usage of both products is
