1) " Extrusion" -- As it applies to Extrusion Equipment Extrusion is a manufacturing process where a billet of material is pushed and/or drawn though a die tocreate a shaped rod, rail or pipe. The process usually creates long length of the final product and may be continuous orsemi-continuous in nature. Some materials are hot drawn whilst other may be cold drawn. Perhaps the most interesting of these processes is the manufacure of pipe where not only is the outside diameter controlled but also either a fixed or floating die is also used to set theinternal diameter and hence the wall thickness. Commonly extruded materials are copper (pipe for plumbing ), aluminium (various Extusion profiles for tracks, frames, rails), steel (rod, track) and a multitude of plastics (pipes, rods, rails, seals). It is common in the plastic Extruxion process to use plastic chip, which is then melted and rather than drawing the materialthrough the die to squeeze the plastic out of the die in a similar fashion to the Exteusion of toothpaste from a tube. Extrusion has found a great application in Food Processing. Various products like pastas, breakfast cereals, ready to eatsnacks, fry-ums etc. are now manufactured by . This article is a stub.

2) " Equipment" -- As it applies to Extrusion Equipment This page discusses common devices known as "tools", for other meanings see Tool (disambiguation) Modern hammer A tool is, among other things, a device that provides a mechanical or mental advantage in accomplishing a task. Mosttools employ some form of simple machine, or a combination of them. Forexample, a hammer simply functions as a lever with the fulcrum (pivot point) being the hand of the user. The further out from the pivot point, the more force istransmitted along the lever. A sword combines a lever and a wedge. Philosophers once thought that only humans used tools, and often defined humans astool-using animals. But observation has confirmed that chimpanzees and other animals, mostly primates, but also some birds ( ravens, for instance) can use tools as well.Most anthropologists believe that the use of tools itself intertwined withthe opposable thumb (useful to hold the tools) and an increase inintelligence (aiding in the use of tools) in spurring along the evolutionof humankind.Most tools can also serve as weapons, such as the hammer and the knife. Similarly, people can use weapons, such as explosives, as tools.
