The importance of finishing

Finishing image of industrial spray painting Finishing any engineering job properly is just as important as any other operation along the production cycle. And by finishing the engineering job, we’re not talking about tidying the file and completing the invoicing. We are talking about the paint or powder coating finish to the product

The appearance of a finished product will always have an impact on the saleability. After all, if something looks rough and unfinished it’s less likely to sell. In addition, there’s the safety impact to consider. Rough edges and burrs can not only put buyers off but can be a serious health and safety risk. So an important part of finishing is to remove those risks.

Hybrid Aircraft – Passenger Planes of the future?

The constant mission to reduce pollution and produce more fuel efficient vehicles led to major research and development in the auto industry. Now all major car manufacturers have a hybrid vehicle in their suite of offerings.

With air traffic forecast to continue to increase there are demands for additional runways and extra services. This, of course causes conflict. Flight companies want to meet the needs of the consumers, but plans for increasing runways and flight services are meeting opposition due to the anticipated increase in noise and pollution.

Could there be a solution? Can we ever have quieter runways and less pollution? Siemens and Airbus think we can!

Research into rail switches at the IRR

Rail switches or ’points’ are used in the rail industry to guide trains to their correct route. They work by using a tapered set of rails (points) lying between the outer rails that can be moved to direct the train travelling across them.

They make up less than 1% of the entire length of railway routes in the UK, yet they account for 20% of the expenditure on track maintenance. With a working life of approximately 3 years, frequent maintenance and replacement of rail switches is needed to avoid disruptions in services.

The Subcon Show is Nearly Here

With only 12 days to Subcon at the NEC in Birmingham 2 – 4 June, PRV Engineering are gearing up for what we hope is another successful show. This will be PRVs 8th visit to the highly successful show which has improved and evolved over the years.

In its 32nd year, Subcon provides a meeting platform for buyers, specifiers and key decision makers from all industry sectors. It’s is a great place to meet, compare suppliers, discover and discuss new technologies and to forge new partnerships.

Why Plate Copper Busbars?

Busbars made of copper are commonplace in the world of electrical power distribution. Switchgear, panel boards and busways all use busbars to convey substantial amounts of electricity, allowing more flexibility for circuits to branch off.

Copper is more resistant to rust and corrosion and so is commonly used in the production of busbars and other electrical equipment.

However, copper does oxidise over time and because of this the resistance in the conductive metal will increase, meaning that more power is needed to carry any current along its surface. Beyond a certain point, the metal can begin to flake and fall apart. It is for this reason that many metals are plated – it helps them retain their positive qualities and attributes.

New Train Carriage Design wins a Share of Funding

Being involved in the rail industry, we at PRV like to keep an eye on the latest developments and innovations coming over the horizon, whether it’s to do with passenger travel, the moving of freight or the development of the trains of the future. So the recent headline about a UK company winning funding to develop a solution for passenger travel and the movement of freight for the future caught our eye.

A St Ives based company has won a share of £2.2m through the Tomorrow’s Train Design Today (TTDT) programme.

Their train carriage design, where passenger carriages can be reconfigured to carry freight or passengers at different times, is one of 3 designs that won a share of the funds to develop the rolling stock of the future.

What next for the auto industry?

The auto industry has come a long way since the introduction of the first car.

Electric and hybrid cars were once thought to be futuristic (along with flying cars). Now electric cars are on every forecourt of major showrooms across the country. Increasing numbers of super fast chargers are being put in place which means that electric and hybrid cars are able to travel much further than when first introduced. In many areas it now only takes 30 minutes to recharge a battery – just enough time to stretch your legs and get a cup of coffee, but a big enough charge to take you another 100 – 300 miles (depending on the model and make of your car).

5 Axis Machining in Modern Engineering

When considering 5 axis machining, it is important to look at the differences between it, and the more common 3 axis cnc system. The most apparent is that a 5 axis system has the normal X, Y, and Z axis but can also rotate on it’s X and Y axis. This leads to a number of distinct benefits.

A major advantage of the 5 axis system is set up, as complex parts can be machined without having to re-set the work piece. This has the two fold effect of firstly, speeding up the machining process as the work piece does not need to be re-set; and secondly accuracy. The zero datum remains undisturbed during the process so reducing the likelihood of production tolerance errors.

Five axis machines can also utilise shorter, more rigid tooling, which is suitable for higher cutting speeds and lower vibration allowing more complex three dimensional profiles and deeper pockets to be cut without the need for a re-set, or a change of tooling. This again helps to ensure the accuracy of the finished part.

Advantages of Steel Framed Building Construction

Advances in building construction have introduced many new and improved options including the use of steel framed building construction. These steel structures are formed through steel framework fabrication. The advantages of steel as a structural design material are well documented. Advantages include the strength-weight ratio that allows steel to bear great weights and ductility, which is the ability to withstand stress for a long period of time and bend without breaking.

Why go for steel framework?
All these same advantages are found in steel frameworks, however the use of steel frames in general has many advantages.

Siemens has recently landed a contract

Siemens has recently landed a contract to provide and maintain trains for the Rhine-Ruhr metropolitan area. The Rhine-Ruhr Express (RRX) is being hailed as the project of the century for the region, whose rail connections and public transport systems have been heavily burdened for years.

The region is one of the largest metropolitan areas in Europe with a population of approximately 10 million, many of which commute along the Rhine and Ruhr rivers in Germany. It is hoped that the RRX project will steadily ease the conditions for commuters from 2018 when delivery of the new trains begins by eliminating thousands of car trips, shifting traffic from the roads and on to rail.
