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.

Five Benefits of Using Brisbane Shopfitting

Shop fitters design, install and make all the fittings that are needed for commercial offices and general retail shops. Apart from simply making or sourcing counters, displaying units and showcasing for shop fronts, shop fitters also carry out general space refit, architectural joinery, doors and floor coverings.

Shopfitters, after what they have proposed, will not only prepare specifications but also provide the plan’s cost estimates. Also, they will come up with plans for construction and design as well as drawings of the shop’s fit out. Additionally, they will also prepare tenders and quotes for subcontractors, like electricians.

5 Benefits of Using Brisbane Shopfitting experts

1). They make you prepared about the realities of the cost
Even before you get to write a brief to the shopfitter, it is important that you have a rough idea of what you want as well as what you do not want. Walk around and see what your competitors have done, do a research on the supplies and fittings that are available in the market and mix this with your retailing experience to arrive at a rough budget.

A professional shopfitter helps you to know the total amount of money that you will be required to spend. After that, you can work with the shopfitter to see where you can save. It can be very sad to realize that as a result of your inexperience, you miss out on an opportunity to save big time.

2). Borrow the experience of other people
Before finalising your premises, you need to start consulting with your shopfitter. These have a lot of experience in shopfitting, and their suggestions may impact the final choice. These people have the ability to see possible cost blowouts on a certain area that you did not even think of.

At the end of it all, the design of the shopfitter ought to reflect your view of the store’s overall concept. As the retail owner, you want something that holds true to the feel that you want. However, the outcome may not necessarily be to your precise specifications. After all, you are just looking for the shopfitter’s creative input.

You may want to consider getting a quote from 2 or 3 outfitters, and also find out the kind of fitout that they specialize in. One of the ways to tell a good outfitter is the way they make use of the entire space that is available.

This way, all the branches will have the common feel and look that the company wants its clients to associate it with. There are certain shop owners who choose to do shop fitting by themselves while others prefer to hire specialty firms or contractors to offer the service. The above are the reasons why hiring a professional Brisbane shopfitting expert is much better than doing the job yourself.

Why You Should Buy A Treadmill – The Health Benefits

The treadmill is one among the most popular pieces of equipment at any gym. The popularity of this piece of equipment may be attributed to the many benefits that people get from using it as an aerobic exercise tool. Treadmills are easy to use and give you the ability to control every aspect of your work out. You can walk, jog or run. The treadmill also gives you the power to diversify you workout routine e.g. you can make a treadmill simulate a hill. Most importantly, people usually reap massive health benefit when they use treadmills to exercise. Here are some of the health benefits of using treadmills to exercise;

1. Reduces the risk of diseases affecting the cardiovascular system

Cardiovascular diseases are a common problem facing many people in the world today. Victims of cardiovascular diseases are usually people that do not work out to keep their cardiovascular system working properly. When you do an intense work out using a treadmill, you strengthen you heart and lungs. By spending at least 30 minutes, 3 to 5 days a week on your treadmill, you significantly reduce you chances of getting heart diseases and many other chronic diseases such as cancer, asthma, arthritis and diabetes.

2. Helps you lose weight

Being overweight not only makes you hate the way your body looks but also puts you at a risk of diseases such as stroke, coronary heart diseases, high blood pressure, type 2 diabetes, osteoarthritis among others. You can burn a lot of calories when walking running or jogging on a treadmill. For example, when jogging at a speed of 9.6 kilometres per hour on your treadmill, you can burn up to 650 calories. If you want to burn more calories, you can simply adjust the settings to increase the speed and/or incline to make a routine more challenging. Therefore, if you want to lose weight the healthy way, get yourself a treadmill. It is the ultimate equipment that any person that wants to lose weight fast should own.

3. Helps to strengthen your bones

When you work out on a treadmill, you create strong healthy bones. You can never be a victim of conditions affecting the bones (such as osteoporosis) if you have been constantly working out on you treadmill. This is because as you walk, jog or run on a treadmill, you put more weight on your bones causing them to grow to be strong.

4. Improves your mood

An intense exercise on a treadmill stimulates your body to produce certain chemicals in your brain that help to bring a ??feel good mood’. The sense of well being that comes from working out on this piece of equipment makes you have a positive outlook on life and can also help you manage stressful situations. Prolonged stress is dangerous because it can lead to serious health problems. Medical research proves that exercising is one among the most effective ways of preventing stress and treating depression. Hence, if you want to relieve yourself from stress, just walk, jog or run on a treadmill as much as you can.

5. Improves your joint motion

If you have suffered back, knee, hip or ankle injury, a treadmill can greatly help you to recover. This is because as you use the treadmill, the joints on your back, knee, hip and ankle are kept in motion. This helps to reduce the stiffness in these joints. Doing a gently walk everyday on your treadmill will help you regain your flexibility by loosening your joints.

6. Increases your energy

When you exercise on a treadmill, you strengthen your heart and lungs. This improves their ability to supply nutrients to oxygen to all parts of the body. The result of all body tissues receiving the nutrients and oxygen they need is increased energy throughout the day.

Treadmills are considered as the most effective cardio machine that can be found in a gym. A treadmill gives you the opportunity to walk, jog or run at the comfort of your home. If you own a treadmill, you will never have to worry about the weather interfering with your work out plans. This explains why they are increasingly becoming common accessories in many homes. Therefore, if you have been looking for aerobics equipment that will keep you body healthy, get yourself a treadmill.

Metal Fabrication – History and Use in Mining Industry

Metal fabrication began in the earliest civilizations when the metals gold, mercury, silver, tin, iron, lead, and copper were discovered. These metals were worked by early artisans into decorative pieces, religious iconography, and jewelry. Items of a practical nature were forged from metal including coinage, tools, and weapons. Using heat and tools, metalworkers began to make functional objects and the industry developed through the years advancing and gaining value from society.

As an industrialised society, the world cannot live without metal; it is essential to almost every industry from mining and heavy industry to agriculture and medical equipment.

Specialist engineers and manufacturers fabricate metal and metal alloys, which are made from a combination of different metals for a staggering number of uses. The pivotal role of metal has been responsible for significant advances in technology, construction, transport, and agri-science. Metal has strength; it is very low maintenance and will last a lifetime and more. Specialist metal fabrication companies are made up of a group of skilled people who all have a role in the process of turning metal into supports for a building, heavy duty mining equipment or boilers and tanks to name a few.

Metal fabrication is a series of processes used to manufacture an object from metal. The specialised equipment involved includes laser cutting machinery, turret punches, machine centers, rollers, welding machinery, water jets, and metal shears. The metals most commonly used for fabrication are aluminium, stainless steel, and carbon steel, which is in the form of sheets, tubing and bars. Most metal objects start life as sheet metal in varying thicknesses depending on the application. Thicker sheets are known as metal plate.

The process starts with the design and then the fabrication begins with the metal sheet being sheared, laser cut or punched into shapes. Once the required basic shape is achieved, the object goes next to the press brake machine to form any bends a process known as forming. Dies are used in the press brake to make the correct accurate shape according to the design plans. The product may be finished at this stage or will be just one component in a series that requires moving on to the next process, which is welding.

Welding is a skilled practice and the artistry of the welder is to take the component parts shaped and formed previously and weld all the pieces together to make the final product in accordance with the design. This final assembly is critical and it is up to the welder to use the welding technique necessary for the job in hand.

Metal fabrication is essential to heavy industry such as mining. The manufacturing of support equipment, skids, conveyor belts, tanks, crushers, drill rigs and hydraulic lifting equipment through to pipe work are all the result of the metal fabrication process. In the mining industry there are very often special requests for one off pieces of equipment that are needed in a hurry and the metal fabrication business that can design and manufacture the product to implementation on site is the company that has the advantage. Metal fabricators may also be called upon to repair equipment or weld a broken object. Mining relies upon rugged, tough machinery often needing custom manufacturing or enhancements making metal fabricators an essential support service to the industry.

Reputable metal fabricators have the ability to design high quality, complex products with precision and manufacture them to full compliance with the specification, which is essential to mining companies who need to be operational at all times. Other metal fabrications for the mining industry include chutes, bins, screen stands, safety guards, stairs, catwalks, platforms and wear plates.

Metal is an essential material for mankind and industry and has the ability to be recycled over and over again which makes it a valuable resource for the global environment. The long working life of all metal fabrications due to its durability means once your product is manufactured, you will not have to worry about it, as it is highly unlikely it will need your attention again.

The mining industry is reliant upon the equipment and the expertise of metal fabricators not only for mine construction but also for ongoing support and maintenance in such rugged environments. For metal fabrication Mackay or metal repairs Mackay, contact 3D Engineering Mackay today.
