Aluminium Plates

Aluminium is a silver, non-magnetic, soft and ductile metal. It is a chemical element with atomic number 13 and the symbol AI. Aluminium makes up approximately 8% of the earth’s crust. It is classed as the third most abundant element, the first two are silicon and oxygen.

Aluminium is known for its low density and resistance of corrosion. Aluminium in various forms such as aluminium plate is vital and are important to the aerospace industry.

Aluminium plate is used in many products such as aeroplane parts, kitchen utensils and window frames.

Aluminium plates can be welded but because of the make-up of the metal is can only be done using a special process. Aluminium can be more expensive than steel and it may warp at high temperatures. It has a lower fatigue limit and will weaken if continually stressed.

Aluminium plates are very long-lasting and sturdy and can easily be melted down and recycled. Aluminium can last anything from 10-100 years before it will start decomposing.

Very thin aluminium plates are used to make the aluminium foil, aluminium alloy is used which contains between 92 and 99 % aluminium and is usually between 0.00017 and 0.0059 inches thick. Some people say aluminium foil is dangerous if ingested but when using it in cooking you should be fine; it will only slightly increase the aluminium in your diet.

Aluminium is only toxic to the body if a person ingests or inhales high levels of aluminium. Exposure is not usually harmful unless in very high doses.

Aluminium is used daily in many objects such as CD’s, refrigerators packaging and computers.

Aluminium can be recycled, it will go through a re-melt process, this will turn into molten aluminium, removing coatings and inks that may be present in aluminium plates.

3 Signs You Need a Cambelt Change

What is a Cambelt and Cambelt Change?

A cambelt or a timing belt is one of the most important and essential components of your vehicle for the operation of your engine. The cambelt keeps the engine in sync, rotation the camshaft and crankshaft in perfect harmony for that comfortable ride that you are used to. It is hard to tell whether you need a cambelt change to the everyday average joe but if left unmaintained can cause exponentially and irreversible damage to your engine.

However, in this article, we are going to explain 3 symptoms that you should be looking a listening out for which could be subtle hints that your cambelt needs to be changed.


What to Look Out For!

There are a few tell-tale indicators to look and listen out for that can be warning you that your cambelt is closed to snapping or is severely worn. We are going to try to break down 3 of the most common and important signs of a faulty or worn cambelt. As soon as you think you notice one of these signs you should take your car immediately to a garage where you can get a quick and easy cambelt change service. Delaying should not be an option for if your cambelt was to snap this would lead to very costly repairs, not only a cambelt change but further engine damage will be caused. When a cambelt breaks the valves of the engine open out of sync causing them to be struck by the pistons. The has a destructive effect on your engine causing bent valves, cylinder head or camshaft damage, possible piston and cylinder wall damage.

Signs That You Require a Cambelt Change for Your Vehicle Include:

High Pitched Noises – If when you start your vehicle you hear a squealing like the sound this is likely to be associated with the vehicle having a worn cambelt which requires replacing.

Ignition Issues – One sign that could mean that your cambelt needs to be changed is if your vehicle is not starting at all. With a faulty or worn cambelt, the camshaft will not rotate when the crankshaft turns, therefore, the engine will not start.

Visual Signs – The best way to check your cambelt is to look at it with your own two eyes. If you can see signs cracking and fraying or the underside appears to look glossy the belt has become warn and lost its integrity. This means the cambelt will not adhere to its flexibility needs anymore as the rubber has begun to harden and should be replaced as soon as possible.

Open Die Forging

Open die forging is also known as smith forging. A hammer strikes the workpiece which is stationary on an anvil. The name for open die forging comes from the fact that the dies do not enclose the workpiece. With each strike of the metal, strength and grain structure is increased. The temperature range that items are created in is 1200 to 1280 degrees.

High Precision Parts

High precision parts cannot be forged using the open die process alone, the products need to be machined to the desired finish. Parts are machined to tight tolerances to minimise the amount of machining required on a finished part. Open die forging is best suited to large pieces on short runs, for example, blocks, shafts, hubs, flanges and cylinders.

Open die forgings have many advantages including incredible strength and a hard-wearing surface finish. This type of forging process is also more economical and creates less material waste.

Range of Forging Materials

A large range of materials can be forged using this method, these include:

  • Alloy steel
  • Stainless steel
  • Carbon steel
  • Titanium
  • Inconel
  • Tool steel
  • Aluminium
  • Copper
  • Nickel
  • Bronze

More advanced open die forging can produce complex shapes even in large products. The biggest drawback of open die forging is that the piece must be moved constantly as it is being worked on, this requires a skilled worker or complex machinery. Closed die forging, on the other hand, is a much simpler process but is often more expensive due to the high setup cost of the dies.

Overall open die forging is a low-cost way of creating simple products quickly but is not suitable for the forming of precision parts.
