what is extrusion process?
491993
Extrusion is a manufacturing process where a material, often in the form of a billet, is pushed and/or drawn through a die to create long objects of a fixed cross-section. Hollow sections are usually extruded by placing a pin or mandrel in the die. Extrusion may be continuous (producing indefinitely long material) or semi-continuous (repeatedly producing many shorter pieces). Some materials are hot drawn whilst others may be cold drawing.\n\nThe feedstock may be forced through the die by various methods: by an auger, which can be single or twin screw, powered by an electric motor; by a ram, driven by hydraulic pressure (for steel alloys and titanium alloys for example), oil pressure (for aluminum ) or in other specialised processes such as rollers inside a perforated drum for the production of many simultaneous streams of material.\n\nCommonly extruded materials are copper (pipe for plumbing), aluminium (various extrusion profiles for tracks, frames, rails, mullions), steel (rod, track), titanium (aircraft components, including seat tracks, engine rings, structural parts), rubber (tire tread and sidewalls), a multitude of plastics (pipes, rods, rails, seals), and grains such as wheat, corn, and rice for food products.\n\nSteel and titanium extrusions use glass powder as a lubricant. This process was invented in France, in 1935 by Mr Séjournet. This solution was patented throughout the world and helped launch industrial steel extrusion. The process was later applied to titanium.\n\nPlastic extrusion commonly uses plastic chip, which is heated and extruded in the liquid state, then cooled and solidified as it passes through the die. In some cases (such as fibre reinforced tubes) the extrudate is pulled through a very long die, in a process called pultrusion.

A process is generally designed to run based on a set of parameters (temperature, pressure, flow rate, etc.).\n\nA process deviation is a variation of the process from the designed parameters.\n\nNote:  The process deviation could be accidental or intentional (such as a test run to determine effect on the process).

many many products can be extruded. the only requirement is that it must have a constant profile. such as wires, catheters, shaving strips, etc. Anything with the same crossectional area essentially. I say essentially because when extruded the plastic can be pulled at different speeds causeing the overall size to differ. Of coarse this is just the tip of the iceburg for extruding.

Deposition is the answer.  Sublimation only refers to the process of solid going to gas.

I don't think there is a "simple" way to describe the process, you could check this out   - http://www.intel.com/technology/itj/2006/volume10issue02/art03_Power_and_Thermal_Management/vol10_art03.pdf

Moulding or mould??? Do you want to make a hull or trim one out? Very different processes.

What type of manufacturing are you talking about.  what industry?

Most hollow tubes are manufactured by extrusion.\nhttp://en.wikipedia.org/wiki/Extrusion \nprovides more information.

B.\n\nthe process is called passivation. and may be increased to a greater extent on purpose by electrolysing aluminum in acid to increase the oxide layer. this is called anodizing.

the answer is that intrusive is formed inside the earth while extrusive is formed on the surface of the earth.

Sheet is the original raw material for stamping.\nOnce it begins processing, it becomes a blank till its completed.

usually a process is the route by which something is converted in something else. process of digestion or cell replication. \n unless you mean the scientific process(like in papers and projects) which is where scientist write out exactly what they did in the experiment.

The most common spooling application is print spooling. In print spooling, documents are loaded into a buffer (usually an area on a disk), and then the printer pulls them off the buffer at its own rate.

The writing process is a list of steps many people believe real writers go through in writing a text. In its most simple form, it has three steps: the "before writing" stage (brainstorming, prewriting, outlining), the "during writing" stage (drafing), and the "after writing" stage (rewording, reorganizing, proofreading).
