Forty-five credit hours were dedicated to designing parts made of plastic, such as electronic enclosures. Three manufacturing processes were covered in detail these were Reaction Injection Molding (RIM), Thermoforming, and Extruding. Blow molding was also introduced. Materials and their common uses and properties were covered along with engineering design techniques such as adding draft, using ribs and fastening methods. |

The part to the right was redesigned with a different material. I selected to use the Injection Molding process and a randomly selected material, Lexan� FL-900 structural foam. This increased the wall thickness to .25 in., expanding outward of the critical surfaces. Structural ribbing, as seen on the original part (fig. 1) was removed. The part would be capable of sustaining a substantial impact with only minor damage. For example, accidentally being dropped on concrete. |
