What are Aluminium Extrusions?

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 Local Council, Federal, Presidential or State election, your mailbox will groan with the weight of materials aimed at getting your vote. It may be the digital age, but it seems that a letter in your letterbox is still considered the most effective way of getting a message across.

While an informed electorate is crucial to the democratic process, there appears to be huge 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 little to no substance. Is anyone else reminded of children in the playground?

How can you help stop this unnecessary waste of paper? Imagine the strain on our environment and the large volume of greenhouse gases generated from all the trees cut down, electricity 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 deemed to be political, educational, religious and charitable is exempt from “No Junk Mail” signed letterboxes according to standards conducted by the Australian Catalogue Association. So there is no way to stop it being posted in your letterbox 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
Much of your mail may be addressed to former 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 polite! 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 volume 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 the last decade due to more options, more expectations and more expense placed on an annual event that runs approximately 2-3 hours. Involved in the kids party industry for over fifteen years, I’ve seen every kind of party from the informal backyard gathering to a veritable carnival with everything imaginable hired.

But don’t be daunted! A child’s party doesn’t need a big budget or an event planner to be a success. Here are some great pointers to get the party started and the kids having a ball.

1. Keep it traditional. Kids love it when predictable elements appear, and if they are overlooked, it will not go unnoticed! Must-haves are: Food, birthday cake, and the all important Party Bag! If you’ve got at least these three things, you’ve got a party.

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

One or two sessions of entertainment are more than enough. The fact is, the kids will be expected to eat now, cut the cake now, watch the gifts being opened now, etc etc.. When you add entertainers, activities and games, the kids can easily be overwhelmed, plus time whizzes by without the kids having time to actually play.

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

4. Age-appropriate entertainment. This directive may seem like a no-brainer, but I have attended many parties that can have children feeling 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 novelty had seriously worn off. And even Pass-the-Parcel can cause distress when played with children who are too young to know they haven’t missed out, they just have to wait their turn. When you are having a party for mixed ages and genders, there is a wide range of entertainment that will appeal, such as jumping castles and balloon-twisting.

5. Try to Relax! When planning a party, plan with your child and use your instincts – you know what they’ll enjoy 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 most importantly, enjoy YOURSELF too…after all -it’s a party!

All the best!

Communication – a fundamental ingredient in a successful relationship

It’s a well-known fact that communication is a key ingredient in a successful marriage. Without effective communication, a couple is unable to discuss important issues and resolve their disagreements. This can often lead to feelings of detachment, anger or resentment in the long term. Although I refer to communication in relationships these tips are equally important in any important relationship in your life.

Communication can be tough, especially if it is with someone you have been in a relationship with for a long time. After a while, couples get comfortable with each other and, as a result, the level of communication tends to decrease. Assuming your partner already knows something or not taking the time to communicate with them can lead to a relationship breakdown over time.

Comfort should not equal less communication. There are many issues that may arise if you don’t keep yourself open and make an effort to communicate with your partner. Follow these simple tips to keep the communication lines open between you and your partner.

1. Never Assume
It’s important not to assume something unless you’ve communicated directly with your partner about it. This could be anything from a roster of household chores, to making assumptions about the way your partner thinks or feels about a particular issue. If you’re unsure, ask your partner and avoid arguments or misunderstandings.

2. Say what you mean
If you have something to say, say it. But make sure you’re clear with your communication and that you’re actually getting the right message across. There’s nothing more confusing (and frustrating) than receiving conflicting messages from your partner. In some cases, it may even help to write your thoughts and feelings on a piece of paper. By writing it down you are able to construct your thoughts in a clear and concise way and ensure you’re getting all the important bits of information across.

3. Don’t be afraid of a disagreement
If you disagree with something your partner has said or done, you should let them know in a calm and reasonable manner. Don’t avoid these conversations for fear of a disagreement. While a disagreement may be difficult to deal with in the short term, an open dialogue about such issues will do wonders for your relationship in the long run. By staying quiet about issues that are important to you, you will only become resentful and angry.

4. Communicate the good, not just the bad
Communication in relationships is not just important when there is an issue to address. If you have something good to say about your partner, say it loud and often. By communicating feelings of love and appreciation with your partner you will nurture the love and trust in your relationship.

5. Make time to communicate
With work and kids and extra curriculum activities it’s easy to see how some couples can’t find the time to communicate with each other. It’s very important you set aside some time on a regular basis to reconnect and communicate with your partner. This may be every day or simply on a weekly basis. Make sure you shut off all electronics and remove yourself from distractions to really focus on what each other has to say.
