extrusion dies how they work and how there maintained?

This is a very technical topic that cannot be fit into this small answer box. However, the following source will answer all of your questions.\n\nThe Aluminum Extruders Council (AEC) released the "Extrusion Dies and Tooling Manual:Recommended Handling and Maintenance."\n\nThis guide is considered one ot the most important reference tools for die professionals. It contains illustrations, charts, checklists, and a glossary. Some of the chapters include: Tool Foundation; Tool alignment; Die Cleaning; and Die Correction.\n\nTo order a copy, call the AEC at 1-847-326-2010

a mould is a container of a specific shape into which a molten solid is poured and left to set into the shape of the mould.\nA die is basically a hole through which semi-molten solid is forced under pressure and it will solidify which the cross-sectional shape of the die.

I would guess it is made from rapid prototyping:- Fused-deposition modeling.  It technique is call Extrusion of melted plastic. there is more information that you can find. Just keep looking..

Install them into your computer as slave drives and access them thru my computer.  Should be able to cut/copy and paste.  If you do not want to open the computer purchase an ide to usb cable or an external enclosure.  Simply make all of the connections and then do the same as an internal hard drive.  WinXP should automatically find  the drives and install the necesary drivers.  I have done it on several old 5.25" hard drives.  I use them as backups, nothing like extending the life of 7 yr old tech.\n\nFirst link ide to usb cables (I personally have the Bytecc)\nSecond link external enclosures\n\nHope this helps.

As an expert with years of experience I assure you my answer is professional:\n1. place the roll on the holder in a manner that permits the paper to hang down from the front.  Check by looking at the right side of the roll when installed to make sure the roll unwinds in a counter clockwise manner.  REASON: it is easier to control the flow of paper and easier to grasp the end of the roll.\n2. when in place on the holder, gently squeeze the roll so that the inner tube forms an oval.  REASON: if the roll is oval, it is easier to control the flow of paper compared to a perfectly round tube because the oval shape stops the paper as soon as you stop pulling.

this looks like the closest thing that I could find that looks like how my old technical manual shows on drawing threads:\n\nhttp://honolulu.hawaii.edu/distance/aec80/threads/20c-ctl.htm\n\nI'll look for more tommorrow\n\naddon\nif you want a 3d thread look around here:\nhttp://discussion.autodesk.com/search.jspa?numResults=25&source=forumlist%7C39&q=3d+thread+spring&inputEntered=true&objID=c39\n\n3d springs are easy to do in 2007 there is a helix command that lets you make a 3d helix that you can use for the path of an extrusion

Cold forming, or cold heading, uses forces greater than a metal’s elastic limit to form shapes without causing scrap material. Since raw material can be the most expensive aspect of a part, cold forming is often a lower cost alternative to screw machining and other manufacturing methods.\n\nBenefits of Cold Forming\nQuality \nImproved strength and reliability through work hardening and an uninterrupted grain flow\nImproved surface finish over screw machined components\nDesign Flexibility\nUnique and diverse shapes, including parts with multiple diameters, extrusions, blind holes and through holes\nLarge head to shank ratios without secondary machining\nEccentric or asymmetrical bodies possible\nReduced Costs\nReduced scrap rates\nHigh production rates\nAbility to form parts to a net or near-net shape, which requires fewer secondary operations to achieve finished form\nAllows multi-piece assemblies to be manufactured as a single component \n\nCold forming often uses significantly less raw material for the same component.

Either injected moulded or turned

it comes from oil the polythene granule "like small peas" or polymer is mixed with various linears and additives such as anti satic, anti slip or slip and master batches to give it colour or strength.then the granule is heat as it goes through a screw and is heat in gradual stages from 0-230c ish depends on polymer type.then the molten polymer is pushed thorough a die from the screw and pull up to a set of rollers "nip" then compressed air is blown into the die to blow the bubble out to the size required. the speed of the rollers is increased to get the thickness "gauge" and then it is put through a set of winders and put on a reel.

I have no idea how legitimate this source is but it does deal with molding plastic. Good Luck!\nhttp://www.epsilonindustries.com/

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.

Below you'll find a link to an exploded diagram for your printer as well as a source for the parts.  Hope that helps you.

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