What are Aluminium Extrusions?

Leave a reply

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.

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.

Tips for Kids Parties

Children’s parties have come a long way in recent times due to more options, more expense and more expectation placed on an event that runs approx. 2-3 hours. Being involved in the kids party industry for over 15 years, I’ve seen every kind of party from the informal backyard gathering to a virtual carnival with a great variety of entertainment hired.

A child’s party doesn’t need an event planner or a big budget to be successful. I have some sure-fire tips to get the party started and the kids really enjoying themselves.

1. Stick with the familiar. Kids love it when predictable elements occur, and if they are overlooked, it will not go unnoticed! Must-haves are: Food, birthday cake, and the all important Party Bag! If you’ve got at least these three things, you’ve got the basics of party.

2. Things for the kids to do. There are so many options: Party games; hire an activity or entertainer or have the party somewhere that will entertain the kids for you. Rule of thumb: DON’T OVER-DO IT!

Just one or two sessions of entertainment are more than enough. Remember, the kids are already being expected to eat now, cut the cake now, watch the gifts being opened now, etc etc.. If you throw in entertainers, activities and games, children can easily be overwhelmed, plus time whizzes by without the kids having time to actually play with abandonment.

3. Play time: This element should be the top party essential. Allowing time for children to play, run about, talk and laugh with each other is golden. It suits children of all ages and capabilities, and -, it’s free!

4. Age-appropriate entertainment. This idea may seem like a no-brainer, but I have attended many parties that result in children being bored or bewildered. For example, hiring a magician-clown for two-year olds left most of the children terrified. Another example is a bowling party for four-year olds. The kids had no interest in being competitive and after just a few bowls, the excitement had absolutely worn off. Even Pass-the-Parcel can cause distress when played with children who are too young to know they haven’t missed out, they just have to wait their turn. When you are putting on a party for mixed ages and genders, there is a wide range of entertainment that will appeal, such as jumping castles, face painting and balloon-twisting.

5. Try to Relax! When planning a party, plan with your child and use your instincts – you know what they will enjoy the most. On the day have a mini paper list so you don’t forget anything, like when to put the party pies in the oven or to hand out the party bags.

Then, enjoy YOURSELF too…after all -it’s a party!

Best of luck!
