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 Dating Sites are gaining success within a niche market

There are 7 billion people populating Earth. With all of this variety available it makes you deliberate as to why there are so many singletons out there.

Perhaps it’s because we live in a fast paced society where people are too caught up to partner up or understand it as a significant pursuit in their lives. Technology combined with evolution has developed a unique breed of people and we do not all share the same commonalities like the good old days.

Today’s Online Dating has comprised itself into an easy access platform for a person to find their soulmate with the click of a button. It is currently a $2 billion dollar per year industry, with over 1500 dating sites internationally and brags to been responsible for around 280,000 marriages as a result of people hooking up. In Australia, statistically 1 in 10 has found love online and 1 in 6 of those people was between the ages 35-44.

There is no doubt the popularity of the ‘General’ online dating websites out there have had huge success with the following of members on their sites. Some international sites proudly promote staggering numbers of 30 million plus. As most sites offer a free sign up it is not quite clear on how many of those 30 million are paying subscriptions, never the less these platforms are connecting a lot of people with each other.

Over time in this industry I think people have gotten tired and confused in the ‘General’ online dating websites. Wasting time on meaningless dialogue and useless chatting only to find out there is not much in common with the other party. Some might say you need to kiss a lot of frogs to discover your prince.

Niche online dating websites have launched on to the scene hard and strong. Obviously someone saw a need and leaped at the opportunity to connect people within a niche market. To tighten the playing field, so to speak. People bond best when they have something in common. Beliefs, hobbies, race, sexual preference or lifestyle choice can categorise people to meet other [compatible~accordant} singles.

Scientists have performed studies to find out if in fact like-minded people or constrasting people make the more suitable couple. It was found that people with similar temperaments and world views were more likely to appreciate success and have conflict free marriages than the opposite couples. It is also implied that people with similar interests were
more likely to meet up in person off the sites.

The niche dating sites available are limitless, probably if you can think it, there has been one created. From Gay to Pet lovers, Christian groups and other religious followings, Asian, Interracial, Vegetarians, Farmers, Cheaters, Beautiful people (ugly people need not apply), Punks, Seniors, Cougars, Sugar Daddies, Military, Single parents, Tall people, big people and even small people. I even managed to come upon a site for inmates, geeks and people who like to dance.

There is no doubt catering to a specific audience could be a very productive market. It sounds like a fun experience to enter a world where everyone shares the same ideals. Everybody deserves love, why not share it with someone you like?

Logo Design Brisbane

When it comes to graphic design, and working with professional graphic designers Brisbane, one of the many techniques that are available to designers is the grid system. Not only does it give a basic structure and starting point for the design work and layout of a page, it is also a simple system that designers turn to, when they are creating content for any number of mediums, from online site design, to magazine layouts.

Content organisation -
The grid system used by Brisbane graphic designers is a method of laying out content, in order to organise that content in a certain way. By using margins, lines, columns, rows, and grids, the system allows designers to properly arrange things out on a page, and lay them out in the most precise manner. Depending on the detail of the site, the content that is being laid out, and the manner in which it is to be seen by the end viewer, one grid, or a combination of grids can be used through all the pages on a site, in order to keep a uniform style, and to lay out the information and content in a certain manner to the end viewer of the site. Once the end result is displayed on screen (or in a magazine, newspaper, etc), the grid lines are no longer seen, but you can still see the consistent pattern if you look through all content, on all pages.

Types of grids and uses -
When graphic designers Brisbane choose the grid layout for site content, there is really no limit as to how many grids can or should be used, how they should be laid out, or how they should be created. It is simply used as a guide, to help lay out content, and give the pages some uniformity throughout. There is a common layout when it comes to grids, and some of the modifications or additions that can be made include:
- Equally sized 2, 3, or 4 column grids, which have a header at the top of the page, and full page grid of squares.
- Varied line, border, and width columns can be created using this basic pattern.
- Changes of page sises which allow for unique page designs, and content layout.
Using the grid system is a great way to lay out any page; it is a simple way to see all the content that will be used on the page, and how it will look once you are finished. Using the grids also allows designers to see whether everything fits together on the pages, how it looks, and whether changes should be made, prior to actually adding content to the sites.

Break out of grids -
Graphic designers Brisbane use the grid as a premise for design, and content layout; but, once the grid is established, and all content has been laid out, it is up to different designers how they are going to, if they are going to, and at which points in the page they are going to break out of the grid. Simple because designers break out of the traditional “grid”, does not mean that the entire system is ignored by designers; as a matter of fact, they use the grid system in many aspects of design and page layout.

Instead of throwing out the grid system, designers may choose to cross over from one grid to the next on the page layout, they choose to extend certain elements to different areas on the grid, possibly extend page breaks to create continual content, and so forth. By breaking out of the grid, designers are able to create a unique layout, they are able to create distinct content, and they are able to design a page and content that is best suited for the client that they are creating that content for.

Like any other guide or premise, Logo design Brisbane use the traditional grid system as a starting point for laying out content. It creates uniformity on a page, allows them to see what looks best where, and eventually it allows them to create, modify, and recreate the grid, in order to design a truly unique site, and one that is the best possible layout for the client they are working with.

How to stop the flood of election junk mail?

Anywhere on Earth, whether it is a State, Federal, Local Council or Presidential 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 a glut of over-sending of junk mail for political purposes – and no clear way on how to solve 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 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 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 dumped 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 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 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!

Permanent Laser Hair Removal Brisbane

Laser Hair Removal is a becoming a popular treatment, as the current fashion for both men and women is to have the clean look consisting of little or no body hair. Excess or unwanted hair growth is usually a result of genetics, hormones or certain medications. Recent advances in the technology have meant that the hair removal treatments are now a lot more effective and there is less risk of side effects from occurring, making it safer for consumers.

When discussing Laser Hair Removal, it is important to note that the body has 3 cycles of hair growth – Anagen (active), Catogen (transitional) and Telogen (resting). The laser energy destroys hairs in the Anagen or active phase, targeting the cells at the base of the hair follicle which are responsible for hair growth. As Laser Hair Removal targets only the hairs in the active phase, only a percentage of hairs are treated with each session. A series of treatments is required to clear an area, though less hair will return with each treatment and the regrowth will become fine, soft and sparse.

Laser hair removal treatments target melanin which is the dark pigment contained within the hair. Red hair contains a different type of melanin and consequently the treatments can be less effective for redheads.
The area must be shaved prior to treatment to allow the laser energy to be directed under the skin, and not to heat up the surface by having dark hair above the skin level. Any plucking or waxing must be stopped for several weeks before starting treatment, as the hair needs to be in the follicle for it to work.

The effectiveness of the Laser Hair Removal treatments is mostly dependant on the quality of machine used, the parameters or correct setting and proper candidate selection. An ideal candidate for Laser Hair Removal has light coloured skin and dark coloured hair. This stark contrast of colour allows the laser light to easily target the hair and pose little or no risk of harm to the skin. This is also why it’s important to avoid sun exposure and tanning when undergoing a course of permanent hair removal treatments.

It is important for the full area to be treated by the laser with each hair removal appointment so hairs are not missed. Any missed patches will require additional treatments in the future and the area may look patchy or have uneven hair growth. Hairs that do not fall out or shed within about 14 days have usually not been treated effectively. This is due to poor spacing by the operator or incorrect technique, which can often be avoided by finding a reputable laser clinic that has licensed and experienced operators.
