Gotta admit, the video you guys put in the beginning which seems like your companies main presentation video is extremely well done and appealing. one of the best I've seen ever.
I worked as an electrician in a plant like this (Alcoa). I worked on all that equipment, troubleshooting faults, etc. That plant is a lot cleaner than the one I worked in.
Trabalho de operador nessas máquina.10 anos processo top .trabalho numa de 6 polegada.tudo automatizada.to saindo dela esse mês pra ir embora pra portugal.sera q vou encontrar fábrica de alumínio pra eu trabalhar
MEU MARIDO ERA SUECO TRABALHOU COM ALUMINIO NO MUNDO TODO ALCOA E ELUMA ERA FANTASTICO CONHECIA TUDO DE ALUMINIO,NO MUNDO TRABALHOU NO JAPÃO ,MALASIA,KUALA LUMPUR, CANADA, EUA, COLOMBIA, AUSTRALIA ETC.... ABB E UMA FIRMA SUECA TAMBEM ,ERA UM GENIO !!
It would be my 3rd night working in an aluminum extrusion plant. I'm completely new to it since I've worked as an overnight stocker previously and do computer work. Definitely different kind of work than I'm used to, but I find it interesting. Still learning though.
I worked for RD Werner from 1990/1996. I was a Die chaser. LOL. Thing's have changed. Nice & clean. The guy loading the die was in no hurry, we changed in under 60seconds. Caustic rooms sucked. Good job though. Good experience.
@Skitad the process at 1:50 is the extrusion. The ram (big rod) pushes the billet thru the die, creating whatever shape the die is. I should know, i run one of these presses for a living!
It was cool seeing the factory itself being put together towards the end of the video. It looks like a massive capital investment. It must take a lot of extrusions to pay off the cost of all that equipment and those dies.
I have an engineering question. If I lay (3) 48x4x.25 strips of aluminum 6 inches apart and screw them in deep and well on 1 inch overhangs on each end will that support 500lbs? It's okay (actually preferred) if they bend a little .
Yo operaba una extrusora así...una 2.800...hay cosas q corregir ahí.falta el gasificado,pronable burbujas d aire si no lo activa ,estirador libera mal.y la cierra corta muy poco las puntas.es probable q la primer camada salga doblada esas puntas...humilde opinion.
That's the "stretching" part.... The pieces are hooked to stretchers at each end that pull in opposite directions until the profile is straightened out
Always wondered how this works. So am I right in saying they heat up the aluminium so it's soft but not melting and then push it through the die like play-doh? Is that it?
+Frank Rizzo hi, My name is Emre NERGİZ from turkey in İstanbul. Our Company is manufacturing Aluminum Extrusion Profile Dies. I want watch my videos. My videos; CAD/CAM/CAE..
+Frank Rizzo Yes when the billet is rammed into the chamber it actually fills the shape of the chamber with huge force(which creates more heat) prior to actually going through the die. Ali is pretty malleable and much lower melting point than steel.
+Frank Rizzo ..Pretty much that is the deal...I worked in Alcoa Aluminum extrusion plant in Los Angeles...1970....things haven't changed all that much....'logs' are heated to maybe 700-750F....extrusion pressure causes more heat and they 'flow' out through the die/s....
Hey Doug, I've got a question, I cast aluminum in sand molds in my garage, is extruded aluminum tougher than non extruded, I know its not forged but it is forced through the die, so I didn't know if that kind of has a forging effect to the metal.
stclairstclair...Yes, extruded aluminum does have a sort of 'grain'....but nothing near the strength of a true forging.... I've spent 4 years at one job milling and welding extruded aluminum (6063)...it machines/welds quite a bit differently than any casting...and any bending should be done across the grain...other wise you can get cracking.
Yeah. I did that in '79. Hot in the plant, then when we started swing shift, the first thing we had to do was drag the racks of extrusions out of the tempering ovens. There was usually one wheel on the rack that stuck...
The mold has two component basicly. Bridge die and cap die that's how it is possible. I suggest you search about it on internet, something visual will help you understand better.
I am looking to designing a railway tank using aluminium extrusion as a material,, how big the size is available. secondly, are they available in angle, as a tank construction would require,,,!
I seen a Mexican guy get caught in the press when I worked in extrusion, it was not a pretty sight, I worked on the saw and it took to long to shut the emergency button off.
