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.

Things to know before you buy night lights

Night Lights are small light resources that are kept on during the night. The intention behind using night lights is to help people find their way in the dark or to help individuals who are afraid of the dark. While choosing the best night lights for you, it is necessary to consider two things: how bright you want these lights to be and howimportant is energy efficiency to you.

What type of night lights are available on the market?

Incandescent Night Lights
The most common night lights use the traditional incandescent bulb. This type of bulb uses a wire filament for the production of light and is not much energy efficient. Most of the incandescent night lights come in the 5-10 watt range.

Fluorescent lights
A fluorescent night light uses almost the same amount of energy to provide a better light output. These lights use about 7 watts of power.

Neon lights
Neon Light offers an energy-efficient alternative by using just about 1 watts of energy. Neon lights carry a small amount of neon gas, which lights up when electricity goes through it. These lights are just outlet-mounted strips that have an electro-luminescent surface. Just like glow-in-the-dark paint or stickers, these night lights emit light while using a negligible amount of power, which is less than even .07 watts.

Things to consider before you buy night lights

The way these lights are powered
Most important thing to consider when buying a night light is how they are powered. Most of the lights are made to be plugged into a wall outlet. However, it is also possible to buy a design that is powered by a battery.

The type of bulb used
One important thing to consider when buying a night light is the kind of bulb used. Night lights that use incandescent bulbs are less energy efficient compared to other designs. Though night lights that use luminescent bulbs are less energy efficient, they produce a much brighter light. They’ll also last considerably longer than their incandescent counterparts will.

Features to look out for

Sensor
Some lights have photosensitive triggers in them that automatically turn off the light when there is an ambient light source present and when bigger overhead lights are on. This sensor also detects the darkness and turns on the light automatically. There are also lights available with sound sensors.

Power modes
Some manufacturers of lights and bulbs also make bulbs with two different modes. In their power mode, they act as a standard 60-watt bulb that gives off enough light to light up the room. In their second energy-saving mode, which may be reached by flipping the switch twice or after twenty minutes of waiting, the bulb automatically dims itself to a 7- W bulb, which is perfect for a night light.

Programmable
Buying a programmable night light will allow you to fix the number of hours for which the light will be operational. This makes these lights much more energy efficient.

Music
Some night lights also play music to assist you in falling asleep. There’re also designs available that have the ability to play specific music. With these kinds of night lights, it is best to select a model that comes with a timer so that it turns off automatically after ten or fifteen minutes.

These were just a few tips to help you make the right decision when you are out to buy night lights. If you want your night lights to be energy efficient, look for ones that use neon bulbs.

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 unhappy 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.
