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.

The Wonders of Polystyrene

Polystyrene is one of the most popular plastics produced today. It is used in a variety of industries, for the production of materials as diverse as packaging for shipping to thermal insulation for homes. There are several types of polystyrene, each offering unique properties influenced by the process used to produce the plastic.

Extruded polystyrene foam (sometimes referred to by the Dow Chemical brand name, Styrofoam) is an amazing material for construction work or any insulation needs. The extrusion manufacturing process produces a “closed cell” type of plastic, a material with an exceptional degree of mechanical strength which also offers excellent water resistance and low thermal conductivity. Low thermal conductivity makes extruded polystyrene an ideal material for insulation in buildings and other applications. The closed cell structure offers high water resistance allows for usage even in wet or humid environments like might be encountered on roofs, walls or even in refrigerated environments where condensation is a leading concern.

Extruded polystyrene is lightweight, nontoxic and easy to work with. It can be cut and bonded with no hassle, giving construction workers the ease of use that lets them get the job done quickly and efficiently. Even very large sections are lightweight and easy to handle, while still managing to provide amazing mechanical strength, high compression strength and impressive thermal insulation properties. Polystyrene insulation is a favored building material, widely used worldwide in private and commercial applications.

Today polystyrene insulation can be found in almost any building. It is used as the structural core and insulation in walls, floors, roofs, refrigerated trucks, cold rooms, and a multitude of other applications. Its useful water resistant properties have even seen polystyrene used as an effective flotation device in the early days of its development, but its most successful applications have been found in building insulation. Buildings insulated with polystyrene can be much more effectively heated or cooled. The low thermal conductivity makes sure your building retains the heat when its cold but can also breath and release heat when its hot.

Architects and contractors have found ways to make polystyrene work for them outside the construction site. It is often used as a material for architectural models. Similarly, it has found applications in the hobbyist recreational model market. While marketed primarily as a building material, the range of possibilities for extruded polystyrene is only limited by your creativity. It has been used by great effective in unorthodox and exciting new ways by tinkerers and inventors the world over.

The production of extruded polystyrene materials is a careful process that has a history spanning back nearly two hundred years. It is a tale of mind boggling advances in chemistry, engineering and modern manufacturing. Today, modern polystyrene products are the result of decades of work by some of the most brilliant minds of the last two centuries. The combination of all this genius has produced an ideal high quality plastic material which provides enough mechanical strength and proper thermal conductivity properties to serve as one of the essential pieces of the modern contractors toolkit. Polystyrene is an invaluable tool which the world would look quite different without.

Kit Homes Compared to Turnkey Homes

There is a major difference between kit homes and turnkey homes. Kit homes are built by an owner builder, one who wishes to build their own home. Whereas turnkey homes are built by professionals, so that the client does not need to be involved with the hundreds of steps and processes involved with building a new home. ”Turnkey” simply means that you, the client, can go to your brand new home, walk up to the beautiful front door and simply turn the key!

The process to become an owner builder is much more complicated than one might think. For instance, it’s a requirement of the Building Services Authority (BSA) that anyone who wishes to build or renovate their own home and spend over $11,000 must hold an owner builder permit, and these permits are only issued by the Building Services Authority once you’ve completed an owner builder course. The permits expire every 6 years.

Here are a few of the processes involved with building your own kit home; legal requirements, site preparation, footings and floors, wall construction, roof construction, windows and frames, doors, screens, wall finishes, ceilings, fixtures, plumbing, gas, electrical, draining, and then some landscaping to top it all off.
If you don’t have experience in all of these areas, building your own kit home could prove to be more challenging than you may think, especially tackling all the council codes, regulations and legal requirements!

We at Bush and Beach Home Builders are professionals at building sustainable homes. We know how stressful and overwhelming the process of building your own home can be, so let us do it for you! If you think assembling a piece of furniture is irritating, building a kit home is a hundred times more complicated. Instead, let us do the work for you so that all you have to do is turn the key and enjoy your unique, climate engineered Bush and Beach home.

Laser Treatments in Brisbane for Tattoo and Hair Removal

Laser Hair Removal is becoming more and more popular as people seek ways to permanently remove unwanted or excess hair. Most people have tried the short term methods such as shaving, waxing or plucking, but are often disappointed with the side effects associated with them.

Laser Technology has come a long way and gets far superior results when compared to other methods of permanent hair reduction, such as IPL or Intense Pulsed Light. Laser also often requires far less treatments due to the effectiveness of the machines and the wavelength used which is specific to the melanin or brown pigment contained in the hair.

The wavelength of light used determines how deep the light or laser energy penetrates into the skin therefore affecting whatever structures lie in that particular layer. IPL or Intense Pulsed Light, as it is multiple wavelengths is better for treating skin conditions such as pigmentation, capillaries and sun damage which lie in a superficial zone within the skin. A hair removal laser (such as the Alexandrite) and its single or targeted wavelength effectively destroys the cells responsible for growing another hair which is located more deeply within the skin.

In a Laser Hair Removal treatment pulses of light are targeted at the area which delivers heat down into the base of the follicle where the root of the hair resides. This short burst of heat disables the hair follicle from growing another hair. As only a certain percentage of hairs are actively growing at any time, it takes several treatments to clear an area of hairs. Most areas of the face and body are suitable for Laser Hair Removal and for those people who suffer from ingrown hairs, they will also be treated with this technology.

A licensed Laser Hair Removal operator will have to have undertaken many hours of supervised training, theoretical studies and laser safety officer tests to attain that qualification. This will mean you get a safer treatment and ultimately better results as they will be more experienced in performing the treatments on many different skin and hair types. Making sure the clinic and laser operators have their licenses on display can also be very reassuring.

When undertaking Laser Hair Removal for the first time it can often be difficult to decide which clinic is going to suit your needs. Price is usually a good indicator of the technology they use as the true medical grade lasers will be a much bigger financial outlay. Cheap prices that seem too good to be true often leave the client with little or no results and in the long run they end up having many more treatments than they first thought they would need.

Look for a clinic that has been in business for a long period of time. Chances are if they are a long standing company they have proven their ability to keep their customers happy. By doing your research before starting permanent hair removal treatments you can be assured you will be getting a high quality, safe and effective treatment with great long lasting results.
