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.

Can I really save fuel with a Truck Wheel Alignment?

Most heavy vehicle owners in the transport industry are asking themselves – How can I save money on my running costs? How can I save on fuel consumption? Will a truck wheel alignment help?

Research & studies conducted around the world show that around 80 percent of medium to heavy vehicles are incorrectly aligned, or have a mis-alignment. If your truck, trailer or bus has incorrectly aligned wheels & axles, you have what we call increased rolling resistance when travelling on the road. This means the engine is working harder than required to push the truck along the road, and the end result is an increase in fuel consumption. Given that fuel can account for up to 50% of the operating costs of a truck or fleet, smart operators must explore all avenues to reduce fuel consumption.
Generally speaking, correcting even slight alignment issues have been shown to result in a saving of 3 – 10 percent on fuel.

3% doesn’t sound too significant does it? Lets take a closer look – One truck runs Brisbane to Sydney (return) 3 times a week (6,000 kms). That’s 312,000 kms a year. Fuel consumption average is 1.85 litres/km. That’s 577,200 litres, current local prices are around $1.49 per litre. Fuel cost for the year – $860,028.00. If you reduced fuel consumption by 3%, you would save $25,800.84!!
Your scenario may be different, but you can see that small changes can make a big difference to the bottom line of your business. There are other areas where you can save on running costs, which will be covered in another article.

If you own one truck or one hundred, and you are not having a regular truck wheel alignment performed as part of your maintenance schedule, you really need to contact your local truck wheel alignment specialist for a chat.

How to Soundproof Windows

Acoustic double glazing depends on the addition of a secondary glazing layer offset from an existing window, optimally by 100mm. Soundblock offer two solutions to double glaze windows for noise and thermal insulation – Magnetic Acrylic Double Glazing and Acoustic Aluminium Double Glazing. Article body:

What is Window Double Glazing?
Double glazing requires the addition of a secondary glazing layer offset from an existing window optimally by 100mm. Retrofit our acoustic double glazing to your existing windows or specify our solutions on new projects. Double glazed windows reduce noise transfer by up to 70% and reduce heating costs by 35%.

Double Glazing System – Magnetic Acrylic Windows
Magnetic Window Soundproofing System works very simply by installing a PVC sub frame on the inside of your window. This double glazing system greatly improves noise removal. The acrylic window is sealed in place, creating an air space with the existing window, thereby producing an insulating barrier.

The benefits of a steel rainwater tank

Queenslandwide steel rainwater tanks are an increasingly common sight across the Australian suburban landscape, and for good reason. We live in a hot, dry country where every drop counts, and many homeowners are eager to protect the earth’s precious resources and save money at the same time. While earlier models tended to be bulky and unattractive, the latest domestic water tanks are specially designed to fit into awkward spaces and complement modern architecture. Steel is proving to be the correct choice, not only for its stylish looks, but for its durability.

Space is a premium on urban blocks with smaller land sizes. Because of this Queenslandwide’s extensive range of custom-size slimline water tanks are increasingly popular in urban areas of Australia, where space is a real problem. These slimline water tanks have evolved so oval tanks, rectangular tanks and other configurations meet the needs of customers who don’t have the space to fit the traditional round water tanks on their blocks.

The benefits of a steel rainwater tank for your home are considerable and will offer you plenty of return on your investment, and you don’t need to live in a rain forest area or a high rain density area to have one.

Australia is now embracing the water tank phenomenon and at Queenslandwide Tanks, we are here to help you with all you need to know when it comes to rainwater harvesting. When you invest in a Aquaplate water tank, you will be able to collect most of the rain that falls on your roof if you have it connected to your gutters and downpipes. For example, if 10mm of rain falls onto about 100m2 of your roof, you will collect about 1000 Litres of rainwater into your water tank. Just imagine, after 4 days of light rain you could easily harvest around 4000 litres of rainwater.

The benefit of rainwater tanks are endless and of course ensures that your home becomes environmentally friendly. You can reduce the amount of water used from the main supply therefore reducing your drain on this precious resource. By reducing the demand on mains water to your home, you will reduce your water bills, and by connecting the rainwater tank to a rainwater pump you will be able to water your gardens, wash your cars and fill your swimming pool whenever you want at no cost.

The other benefits of installing a Slimline rain water tank in your home are the government rebates now available to residents across Australia. And did you know that rainwater is actually less salty than dam supplies therefore it is much healthier for your gardens and appliances like your washing machine as they will actually be better of using rain water. The other benefit of owning rain water tanks means that you will never have to worry about water restrictions around the home for washing your car and watering your garden.

Imagine how easy it would be to wash your car with rainwater whenever you like, and imagine how beautiful your lawn and plants are going to look when you start using rainwater for your garden.

It’s best to use the water in the tank on a regular basis so there is always storage capacity available in the water tank when it rains. By connecting your water tank to a washing machine or toilet, you will get good use of the tanks supply and will allow rainfall to re-fill the rain water tank more often. By using the water tank this way you will maximize the amount of rainwater you will harvest and the money you will save.

How to stop the flood of election junk mail?

Anywhere on Earth, whether it is a State, Federal, Presidential or Local Council election, your mailbox will groan with the weight of materials aimed at winning your vote. It might be the digital era, 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 important for 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 fix this. What’s worse, the content of most of the political flyers is simply mudslinging about their opponents with no 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 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 deposited 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 probably 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 every 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 curb 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!
