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.

The Typical Queenslander Style Home

When you think of a typical Queenslander, apart from the massive stilts and open-plan design, one of the most recognisable qualities is the corrugated iron roof.

Since the 1840s when Australia was first developing, corrugated iron has been considered one of the best materials to use for roofing. Because of it’s lightweight, sturdy properties, it is the ideal material to use in terms of easy transportation and construction as well as protection.

Although it is a relatively strong, fire proof and weather-resistant material, if exposed to water (particularly salt) rusting is inevitable. This is why it is extremely important to coat the steel in a layer of paint in order for it to remain protected.

Even today this roofing remains to be one of the most popular choices in materials for a range of reasons. Its flexibility, strength and thin sizing allows for quick repairs, relatively cheap installation and durability with little maintenance.

Apart from the practical side of things, there is also the aesthetics. The typically 3 inch curves rolling into one another create a very symmetrical feel, breaking up the angles of the rest of the house and creating a harmonious contrast.

Since iron is quite a durable material itself, compared to wood it is very easy to prepare for installation. Instead of needing to purchase an expensive sealant, a few layers of paint will generally be enough to prevent any damage.

One aspect of corrugated iron that can pose a genuine issue is the fact that the wavelengths of most sounds are echoed loudly into the tube of the corrugated iron. This means that any noise close to or coming into contact with the roof is going to release a high pitched “ping”. This can be a genuine issue for Queenslanders as falling tree branches and wildlife are a part of our every day lives.

On the other hand, the echo can be the perfect culprit to amplify raindrops into a soothing lullaby and because of the shape of the typically 3 inch tubing and smoothness of the iron, the water runs straight down and off the roof, making cleaning very manageable. Also because it is a very thin material it allows the house to stay cool in the warm summers, making it the ideal choice for a house in Queensland.

The iron sheets themselves are relatively cheap and can be purchased with a coat of Colorbond or made galvanised to order. They range from around 5 to 45 dollars per sheet depending on the size of the sheet and what coating you have selected.

Compared with other common roofing materials such as clay, slate, concrete, wood, Spanish and asphalt, corrugated iron is often said to be one of the most durable and certainly one of the most cost-effective.

So whether it’s the classic sound of rain on the tin roof, or the practical desires of someone looking for a sturdy home, or anyone who doesn’t want to waste their precious pennies, it is no surprise that corrugated iron is one of the most popular choices in Queensland.

Shrink Wrap Film – Retailers Love It

Manufacturers across the divide continue to produce quality products. We are all too familiar, with the attractive transparent packaging of toys, imported fruits, clothes, pens amongst other things. Unlike the previous times, customers can still have a glimpse into their prospective purchases, carefully examining them without necessarily compromising their state or quality (food).

It is as a result of these demands that the shrink film was developed. In the formative years; we were all accustomed to the brown paper bags which had our tree population on the decline. Subsequent move to the opaque store-name-christened polythene was a further disservice. Then came the perfect solution to all these problems, the shrink film.Initially, the shrink film was exclusively made from PVC (Polyvinylchloride).This is a plastic polymer (third most used plastic in the world) that had the capability of sealing products with a thin layer of plastic sheet. These sheets were often transparent to allow the customer have a view of the product.

The sheet would be wrapped over the product and passed over a heat tunnel or a heat gun. Normally, the length or circumference of the product would be measured, 10% of this value would be added then the sum is divided by two, this would give the size of PVC shrink wrapping to be used. PVC has the ability to shrink by 40% percent giving the packaging a tight grip of the product.

However, with time it was noticed that PVC could release small amounts of hydrogen chloride giving the products a characteristic smell in addition to poisoning. The sealers also would have small carbon deposits. The presence of a plasticizer in PVC had the drawback of hardening and shrinkage during cold weather and extreme stetching with subsequent temperature increases.

These drawbacks meant a suitable shrink film devoid of a plasticizer be developed. Polyolefin was found to have the packaging abilities of PVC but lacked the setbacks that faced the latter. It became a preferred choice of packaging. Offering a stronger seal and fewer odours. Its lack of plasticizer meant no physical changes to the shrink film. It would become the perfect storage solution; all weather .Lack of chlorine in its polymer meant no hydrogen chloride previously characteristic of PVC.

However, while its predecessor PVC enjoys machine compatibility and low cost purchases, polyolefin is the opposite, it remains relatively expensive and hard to use alongside machines.PVC on the other hand remains a suitable choice for manufacturers who don’t deal with edible products. Owing to its cheap price and machine compatibility it is a manufacturers darling.

It is of note that, both polymers are ideal for different packaging purposes. The choice of shrink film is determined by the product, budget and level of technology the producer in question has.

The undeniable fact is, packaging being the cornerstone of branding and advertising can be responsible for high sales volume or the reverse. Manufacturers and producers alike are today faced with the tough task of choosing the ideal packaging material. In the end the functionality of the shrink wrap can only be determined by the manufactures and producers.
