Thanks to the Industrial Revolution, the production and even design of nearly every product that companies use throughout the world moves at high speed. During the 20th century, most companies considered manufacturing as being an ‘all or nothing approach.’ In other words, creating new products (manufacturing) was a complicated process that required the proper designs and ultimately the right moulds that would be used in their manufacture. It was often too costly to create moulds and products for anything less than large orders.

Today, the global population has moved beyond seven billion and even though there are more people than ever, there is also a growing need for products to be manufactured on a smaller scale. We are PRV Engineering are often called upon to create these small scale or even jobs where we manufacture one off parts.

Throughout Great Britain, and actually around the world, governments –both national and localised- have been seeking out signs of economic recovery and growth. Investors and legislators have been carefully watching all economic reports and indicators, interpreting data and attempting to provide assistance to companies and industries that show signs of strength. Thanks to PRV Engineering in New Inn, there are signs that manufacturing and engineering in the country are beginning to expand.

When the country is looking for any signs of economic growth and stability, during the past few years those signs have been meagre, to say the least. Today, though, PRV Engineering has announced that due to considerable growth during the past two years that we will be expanding its capacities and operations, with the intent of creating up to thirty new jobs over the next few years.

Keeping costs down is generally considered an important caveat of a healthy industry, but when it comes to industries such as the railroad system, there are more issues at stake than merely keeping the cost of tickets down. Safety in an age of threats, both foreign and domestic, as well as the high rate of copper theft that has been affecting the railway industry are just two examples of the issues that are affecting the commuter railway world.

The idea of cutting costs is certainly one that will be agreeable to a number of people, but the plan has to pass a number of criteria before it can be determined to be effective in the long run.

Anthony Smith, who is the Chief Executive of Passenger Focus, a watchdog group that has the interest of the riding public in mind, believes that there is certainly a need to have a more cost-effective railroad for the consumers, but he isn’t convinced yet that the simple act of cutting costs is going to have the right impact on the public at large.

He states, ‘How will it affect the way we travel? [The plan] need[s] to pass two tests: will passengers find the changes both affordable and acceptable?’ If consumers don’t find these cost cutting plans to be either, or preferably both, the long-term effects, such as reduced ridership, revenue, and more can have a greater bearing on those long-term costs that the government is aiming to save.

Regulations that will go into effect in the future under this cost cutting plan will also be a factor in impacting how the major companies deal with the shared costs of operating their rail lines. Some of the proposed regulations also indicate the potential for mismanagement and misuse, such as allowing individual operators to charge more for busier times. During the commuter rush hours, there are currently no provisions in place with this cost cutting plan to limit or cap the amount that can be charged for specific fare times.

However, it is important to note that while the government plan is to cut 3.5 billion pounds from the cost of operating the railway throughout the UK, as reported by The BBC, they are exploring all of the options available to them in order to ensure that they not only achieve the greatest cost savings, but that it also benefits the riding public as well. One final doomsday note comes from RMT general secretary Bob Crow who admonishes this proposed legislation, stating that it will return the industry to the days of disasters, such as Hatfield and Potters Bar.

The coming months of debate will highlight the full potential impact of this proposed cost cutting legislation.

Thanks to the massive advances in modern computer technology, more consumers are hitting the road, or their commute, with mobile apps, phones, and tablets. The revolution in internet technology and capability means that while websites have become an integral part of modern business success, more and more people are connecting to the internet through their mobile devices. This also means that the full size and fully functioning websites that are designed and built with the regular computer in mind (all that RAM and working memory), need to be streamlined to operate effectively on these mobile devices.

Plasma cutting has been in use since the 1960s.  Today it is a widely used metal cutting process.  Unlike conventional “metal against metal” cutting, plasma cutting doesn’t produce metal chips so it can create accurate cuts.

Although initially plasma cutting was quite time consuming and expensive, it emerged as a more user-friendly, economical and productive method by the 1980s, due to the application of modern engineering techniques.

Here we discuss the different methods of plasma cutting as well as how it works, applications and pros and cons of utilising it in an engineering application.

Plasma Cutting Processes

First, there are three major processes used for plasma cutting:

Air plasma – In general, a hand-torch is used for metal cutting in this system. It is considered to be the most portable plasma cutting option. In most cases, it uses inverter power supply technology. The important features of this process include:

    • The system can run within a power output range of 12 amps to 120 amps
    • Cutting thicknesses can be achieved as low as 1/8 inch

Mechanized plasma – This conventional plasma cutting system is extensively used in shipyards, steel service centers and heavy-equipment manufacturing companies in order to obtain high productivity. The notable features of this technique are:

    • Uses machine-mountable torches
    • Available in amperages ranging from 130 amps to 1,000 amps
    • Cutting thicknesses of up to 61⁄4 inches can be achieved
    • It requires constant manual monitoring on different factors, such as gas flow, pressure, arc voltage

High definition plasma – This system has emerged as the most viable metal cutting solution in the industry over the last two decades. After its introduction in the 1990s, it went through several research and development processes. High quality cuts, economical operating cost and high cutting speeds are some of the major benefits of using this system. Initially, it had a thickness capacity of 3⁄8 inches. However, with advancements in engineering technology, now cutting thicknesses of up to 3 inches are easily achieved.

Some of the important features of this process are:

  • In order to achieve quality in cutting, plasma cutting equires monitoring by expert operators
  • Cutting thicknesses can be as low as 26 gauge to as big as 3 inches. When used on carbon steel, thickness capacity of up to 61⁄4 inch is also achievable
  • It requires power levels ranging from 130 amps to 800 amps
  • Technology updates on plasma cutting methods are continuing to evolve in order to obtain better results in cut quality and productivity

Shot blasting has emerged as one of the most effective, as well as possibly the cheapest technique for surface preparation prior to operations such as galvanising, electroplating, welding, enamelling, glass coating and rubberising.

Shot blasting is useful for many industries, including the aerospace, ship building, forging and steel industries because it provides a consistent and uniformly fine, rough or matt surface depending on the techniques and tools used and the type of surface required.

Previously we published the post Shot Blasting Techniques: Things You Should Know but we felt that we’d now like to take this opportunity to talk a bit more about the actual benefits of shot blasting over and above other techniques often used for surface preparation.

Plus we’d like to lay out the types of shot commonly used and describe the situations they work best in.

So here are some of the major benefits associated with shot blasting as a surface preparation technique

  • Shot blasting eliminates the usage of non-eco friendly and harsh chemicals
  • Shot blasting provides higher production rates, wider abrasive selection and better blast pattern accuracy
  • The finished surface obtained is absolutely free from chemical deposits, scales and dust content. Shot blasting does not remove any virgin metal when removing scales
  • Shot blasting facilitates the formation of a permanent bond between the protective coat (zinc, paint or epoxy) and the shot blasted surface. It also helps to detect surface faults or defects
  • Shot blasting increases longevity and durability of protective surface coats as it adheres better to the shot blast cleaned and scale free surface

These are some of the many reasons why industries in the manufacturing sector opt for various shot blasting techniques for their surface preparation requirements.

Shot Blasting: Types of Shot Used

While shot blasting primarily refers to blasting the surface with small steel pellets or shots, many other types of shot blast materials are also used. Here we will take a look at some of the commonly used shots –

  1. Steel Shots – Here, small steel balls of diameter 1 to 6 mm are fired at high speed against the surface being prepared. The size of the balls determines the finishing achieved. Smaller steel shots are used for more polished surface, while larger ones lead to a rougher finish.
  2. Chilled Iron Grit – These are angular, abrasive material used for general blast cleaning, i.e., for removing oxides and paints from ferrous castings and carbon steel. However, blasting with chilled iron grit is quite aggressive and therefore not suitable for softer metals like aluminium.
  3. Steel Grit – Blasting with steel grit is used for jobs where aggressive cleaning is required, such as for removing contaminants from steel or any other metal.

As one of the leading engineering services, PRV Engineering Ltd, can provide you with state of the art shot blasting services for all your surface preparation requirements.
