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.

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.

GRID-BASED LAYOUT METHOD FOR WEB DESIGN IN BRISBANE

With any beautiful design or structure, from architecture to painting, there lies beneath it a grid-based layout from which these creations were originally derived. It is, in essence, the unseen mathematical component of all design that, for many web designers, has become standard in the pursuit for the perfect web design.

To understand what a grid-based layout for web design is, we first need to understand why it is referred to as “grid-based.” A grid is a structure consisting of intersecting straight vertical and horizontal guidelines that are made up of margins, flow-lines, columns, rows, gutters, modules, and spatial zones. This potentially complex composition provides the perfect structural base that allows a web designer to create graphic elements from, or to organise content within. It is this reason that grid-based layout is used in web design.

By using grids in the website design a sense of uniformed structure is achieved for the overall website, this helps achieve better usability for website visitors as they are able to navigate and engage with the website much easily than if the content was simply thrown together without structure. Another reason grid-based layouts are used is efficiency. By designing to a grid, the actual design process is simplified because design guidelines are already in place, therefore making it easier to decide on design elements, such as width and height.

When using grid-based layouts in our web design, we can either create our own grid, or download a ready-made grid template. If we create our own grid, we will need to rely on what option works best for us and the web design project we are working on. It is therefore valuable to follow some simple guidelines when creating our own grids. These are:

• Use only enough columns as needed for the web design. In other words, if you are only going to use ten columns, then only create ten columns – and not twenty.
• Watch the spacing. As a general rule, columns should have the same number of pixels across as rows are high.
• Don’t box yourself in. If you need to move outside of the grid for specific graphic elements, then do so. A grid is only there for structural support, and is not the end product.

If creating your own grid-based layout isn’t appealing, or you simple do not have the time to invest in it, then downloading a pre-designed grid template is available. There are many online sources that provide such templates, and by downloading a grid template you can save on time and have, at your disposal, an effective grid template ready to use.

It is important to re-emphasise that grid-based layouts for web design should not be mistaken for a strict rule by which all graphic elements or content must adhere to. Naturally, when creating anything we can move beyond specific rules in order to achieve our creative goal, and grid-based layouts are no different. If we use grids as a structural guide in our web design, then we are better able to create amazing web designs that will not only appear organised on our web page, but will hopefully inspire and engage every website visitor.

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.
