Shot blasting is used to clean, polish or strengthen metal preparing it for the application of overlays or specialist coatings. It is a technological process used to remove various impurities from different surfaces using abrasives. This includes removing rust or old layers of paint to prepare surfaces for further processing like painting, welding or powder coating. Many industries working with metal use shot blasting, including aerospace, automotive, construction, shipbuilding, rail among many others.

The defence sector is a demanding industry as companies from all over the world compete for new innovations and technologies. From tanks and armoured personnel carriers to autonomous vehicles and helicopters, countries are always looking to expand their defence forces.
We’ve recently covered some really interesting defence technologies ranging from micro drones to UAVs and military robots. Looking at some of the developments from 2018, the Israeli Defence Force springs to mind.

Military vehicles and robots date as far back as WWI with small, remote-controlled and tracked, disposable explosive devices. WWII saw even more innovative designs with the Soviet Army developing full-sized remote-controlled tanks between 1930 and 1940. Even the Brits had a hand in remote controlled tanks with their Matilda MK2 Infantry tank, the ‘Black Prince’.
While nothing compares to modern day military vehicles and autonomous systems, our history is filled with incredible engineering feats. With so many different autonomous military vehicles and systems, we’re only focusing on a few of the standouts.

BAE Systems has been a trusted supplier to the US Marine Corps for more than 70 years. Their most recent engineering accomplishment is the next-gen ACV 1.1 Amphibious Combat Vehicle. Set to replace the current range of Amphibious Assault Vehicles (AAVs), the new vehicle offers improved survivability.
This particular combat vehicle was designed from scratch to meet the real mission challenges of deploying Marines from ship to shore. The ACV 1.1 is a combination of the long history between BAE Systems’ amphibious legacy and Iveco Defence Vehicles’. Together, they have produced more than 30 000 multi-purpose armoured vehicles with the latest variant a certain standout.

Several industries currently benefit from aluminium fabrication, which relates to the construction of metal structures by means of cutting, bending and joining. Most extrusions go through some form of further processes such as fabrication, machining and surface treatment. The properties of aluminium make extrusions highly suitable for almost any type of fabrication.
Although fabrication can be applied to any metal, aluminium is considered one of the most common. As a result, there is a big demand for aluminium fabrication services all over the world. If you look at your home or office building, aluminium is all around us. Some of the most common features are aluminium gates and aluminium frameworks used for doors, windows and showers.

Tin and silver plating are essential for components designed to carry heavy electrical currents such as Busbars. It’s believed that silver is the best metal for conducting electricity making it a popular choice for electronics and semiconductors.
At PRV Engineering, we provide a high quality painted finish to very exacting standards. Our plating facility is testament to how we operate in terms of quality finish and zero tolerance on rejects. There is no better way of controlling quality than by doing it yourself which is exactly what we do.

You may already know what electroplating is but what you may not know is how it works. Electroplating can be described as a common metal finishing or improving process used in a number of industrial applications.
It’s not new though as the earliest form, which became the modern electroplating process, occurred in the early 19th century. At this time, the development of bigger electric generators meant higher currents which drastically improved the process. With the advancement of industrial and manufacturing practices over the past two hundred years, this process has greatly evolved.

The USS Gerald R. Ford (CVN-78) is Marine Engineering at its best. It houses more than 4 500 crew members and weighs in at 90 000 tons. With a $13 billion price tag, it’s the most expensive and most advanced warship ever built. It certainly sets the bar extremely high.
Christened in November 2013 and scheduled to be commissioned this year, these super-carriers are expected to be in service until 2065. They are also set to replace some of the Navy’s existing Nimitz-class carriers.
Both classes have a similar-looking hull but the Ford class is miles ahead with new technical and technological innovations. Designed to improve operating efficiency and reduce operating costs, the USS Gerald R. Ford also requires fewer crew; about 600 to be more specific. It’s estimated to save $4-5 billion on operational expenditure making it extremely cost effective in comparison.

There are a few reason for plating or coating busbars. Cosmetic reasons or provision of insulation are a couple but the most common reason for coating busbars is to inhibit corrosion.
Busbars are commonly made from copper, which in itself is quite resistant to corrosion but busbars are often used in environments where higher levels of protection are needed. Over time, copper oxidises and can impact the surfaces conductive properties. So plating or coating busbars, not only reduces corrosion but also improves the longevity and conductive properties of the item.
