Forging, Castin, and Machining


 * Casting: ** Heating metal to then pour into a mold to get desired shape.
 * Forging: ** Using (lots!) of force to change solid metal into a desired shape.

 * Machining**

Most common form of plastic molding. Pellets are heated to make a thick liquid like texture. They are "injected" through paths into a mold and allowed to cool and then released from the mold. The "paths" then need to be trimmed from the actual part. You can usually find this spot on a product and it looks like a "belly button". media type="youtube" key="cANvFsvY0Aw" width="206" height="117"
 * Injection Molding -**

General concept is that a "nugget" or preformed piece of plastic is placed into a mold. Mold is closed and air is pushed into the plastic. Plastic is blown or pressed against the mold. media type="youtube" key="NE4c1gwzPb4" width="208" height="118"
