What are Aluminium Extrusions?

Leave a reply

Extrusion is a process used to create objects of a fixed cross-sectional profile, of solid round, square or rectangular shapes, to L shapes and T shapes, tubes and many other different types. Metal is pushed through a die of the desired shape using either a mechanical or hydraulic press, resulting in the finished product. The cavity in which the raw material is pressed is lined with a wear resistant material which can withstand the pressure that is created when the material is pushed through, making extrusion possible without deforming or tearing the metal.

Aluminium extrusion is generally used in the manufacture of windows, doors and balustrades, but is also found in thousands of other items like vehicle parts, truck trays, boats and other marine products and refrigeration, etc to name a few.

Two advantages of this technique over other manufacturing processes are its ability to create very complex cross-sections, plus being able to work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms finished parts with an excellent surface finish. Extrusions often minimise the need for secondary machining. They are not of the same dimensional accuracy or surface finish as machined parts, however, the process produces a wide variety of cross-sections that are hard to produce cost-effectively using other methods.

Extrusion may be continuous (producing indefinitely long material), or semi-continuous (producing many pieces). The minimum thickness of steel is about 3mm, whereas aluminum and magnesium is about 1mm. The extrusion process can be done with the material hot or cold.

Metals that are commonly extruded:

* Aluminium is the most commonly extruded material and can be hot or cold extruded
* Brass is used to extrude corrosion free rods, automobile parts, pipe fittings, engineering parts
* Copper pipe, wire, rods, bars, tubes, and welding electrodes
* Lead and tin pipes, wire, tubes, and cable sheathing
* Magnesium is used in aircraft parts and nuclear industry parts, and is about as extrudable as aluminum
* Zinc rods, bars, tubes, hardware components, fittings and handrails
* Steel rods and tracks -Usually plain carbon steel is extruded, but alloy steel and stainless steel can also be extruded
* Titanium is often used in aircraft components including seat tracks, engine rings, and other structural parts.

Clean Metals for Recycling

The cleaner that a metal is when it’s taken into a scrap metal yard to sell, the better price it will fetch per kilo, as foreign matter is costly to clean off, so this product will always be penalised accordingly in terms of the price. By this we mean no concrete, screws, glass, paper or any other foreign material attached.

All the metal we buy is processed by cleaning any non-metallic off it as required, cutting it into smaller pieces, and then it is put through a baling press to maximise the weights for export to South East Asia, where it will be melted down and manufactured into new products.

The Extrusion Process

The process begins by heating the material (for hot or warm extrusion). It is then loaded into the container for pressing. A dummy block is placed behind it where the ram then presses the material to push it out of the die. Afterward, the extrusion is stretched in order to straighten it. If higher quality properties are required then it may be heat treated or cold worked.

Cold extrusion is done at or near room temperature. Advantages of this over hot extrusion are the lack of oxidation, higher strength due to cold working, closer tolerances, good surface finish, and fast extrusion speeds if the material is subject to heat for a short period.

How to stop the flood of election junk mail?

Wherever you live in the world, whether it is a Presidential, Local Council, State or Federal election, your mailbox will groan under the weight of materials aimed at getting your vote. It might be the electronic era, but it seems that a letter in your letterbox is still considered the most efficient way of getting a message across.

While an informed electorate is crucial to the democratic process, there appears to be a glut of over-sending of junk mail for political purposes – and no clear way on how to stop this. What’s worse, the content of most of the political flyers is simply mudslinging about their opponents with no intellectual substance. Is anyone else reminded of children in the playground?

How can you help stop this frivolous waste of resources? Imagine the strain on our environment and the large volume of greenhouse gases generated from all the trees cut down, printing and transport of the materials. Grab a cup of tea or your water bottle and let’s get down to it.

We know in Australia that material that is deemed to be political, educational, religious and charitable is exempt from “No Junk Mail” signed letterboxes according to standards developed by the Australian Catalogue Association. So there is no way to stop it being posted in your postbox along with the other junk mail catalogues enticing you to buy all sorts of things you don’t really need. It is likely the same in other countries.

Step 1. Incorrectly addressed political mail
A lot of of your mail may be addressed to past occupants of the house. You need to “return this to sender” with the note “no longer at this address”.

Step 2. Contact each political party or politician that is mailing you
There is no central database so you will need to call the office of each individual sender and ask to be removed from their mailing list. Remember to be nice! You catch more bees with honey than vinegar.

Step 3. National Standard to stop political junk mail
Write a letter to the Electoral Commission asking them to implement a National Standard to limit the number of pieces each political party is allowed to put in each household’s letterbox.

Step 4. Polling day
Don’t forget to recycle any materials you are given on the day – often the Greens Party has a box at the booths for such materials on polling day!

Tips for Kids Parties

Children’s parties have come a long way in recent times due to more options, more expense and more expectation placed on an annual event that runs approximately 2-3 hours. Working in the children’s party industry for over 15 years, I’ve seen every type of party from the informal backyard gathering to a veritable carnival with everything imaginable hired.

However, a kid’s party doesn’t need an event planner or a big budget to be wonderful. I have some great tips to get the party started and the kids having a ball.

1. Stick with the familiar. Kids love it when predictable elements are present, and if they are overlooked, it won’t go unnoticed! Definites are: Food, birthday cake, and the all important Party Bag! If you provide at least these three things, you’ve got a party.

2. Things for the kids to do. There are innumerable options: Party games; hire an entertainer or activity or have the party somewhere that will entertain the kids for you. Rule of thumb: DON’T OVER-DO IT!

One or two entertainment events are more than enough. The fact is, the kids will be commanded to eat now, cut the cake now, watch the gifts being opened now, etc etc.. If you throw in entertainers, activities and games, the kids may quickly become overwhelmed, and the party whizzes by without the kids having time to actually play.

3. Play time: This element should be the top party essential. Allowing time for children to run around, play, talk and laugh with each other is golden. It suits children of all ages and capabilities, and what’s more , it’s free!

4. Age-appropriate entertainment. This tip may seem like a no-brainer, but many parties result in children being bored or bewildered. For example, hiring a magician-clown for two-year olds left most of the children terrified. Another example is a bowling party for four-year olds. The children had no interest in being competitive and after a few bowls, the excitement had absolutely worn off. Even Pass-the-Parcel can cause distress when played with children too young to realise they haven’t missed out, they just have to wait their turn. For a party for mixed ages and genders, there is a broad range of entertainment that appeals, such as jumping castles and balloon-twisting.

5. Relax! When planning your party, listen to your child and use your instincts – you know what they will enjoy the most. On the day have a mini run-sheet so that you don’t forget anything, like when to get the party pies in the oven or to hand out the party bags.

And lastly, enjoy YOURSELF too…after all -it’s a party!

Best of luck!
