Do You Know How The UK Coins Are Made And What Are They Made of?

image

The processes involved in producing a coin can be broken down into three different sections: making the blanks, making the dies and striking the coins.

Making the blanks

Depending on the alloy required, the appropriate metals are melted in the necessary proportions in a furnace. The metal is then extracted from the furnace in the form of a continuous strip, which is cut to produce coils weighing up to 2.8 tonnes. The strip is passed through powerful rolling mills to reduce it to the thickness of a coin. Blank discs of metal are then punched from the strip in a blanking press at a rate of up to 10,000 a minute. Rolling metal under great pressure makes it hard so the blanks have to be softened, something which is achieved by heating them in an annealing furnace at up to 950°C.

Making the dies

Once a design has been approved, a plaster model is prepared at several times the diameter of the intended coin. The plaster model is scanned by a ruby-tipped probe which records the design as a digital file on a computer. Guided by this digital file, an engraving machine cuts the design into a piece of steel at the correct size of the coin. Known as a reduction punch, this piece of steel is then used to make the dies which will actually strike the coins.

Striking the coins

For the final stage of the process, the blanks are fed into a coining press containing a pair of dies. Applying a pressure of around 60 tonnes, the dies strike the blanks and turn them into coins at speeds of up to 850 a minute.

Forget Home Furnishings, IKEA Enters The E-Bike Market

IKEA has certainly surprised us with many clever home-furnishing solutions. Most importantly, IKEA, with its roots in the super “green” country of Sweden, could not leave its homecountry’s highly socially conscious citizens disappointed. When it comes to act environmetally friendly, IKEA comes right up in the top list worldwide as leader of clean technology. In fact, IKEA has big goals for 2020 that includes a plan to obtain 100% of the energy it consumes in its stores and buildings from clean energy and to grow more wood than it uses.

Plastic bags were far gone six years ago, CFLs and LEDs were introduced as replacement for high-energy consuming incandescent light bulbs back in 2010, affordable home solar panels were recently made available in the UK, a number of electric car stations were installed at stores across the world and now IKEA has entered the electric bike market.

Yes, e-bike FOLKVÄNLIG can be found in two IKEA’s retail stores located in Vienna, Austria. Still in its inception phase, the e-bike is expected to become viral and shortly reach out to many different stores. The electric bike’s design has already received various awards at the Taipei Cycle Show, Eurobike and the IF Design Award.

FOLKVÄNLIG in Swedish means ‘user- friendly’, which is probably what IKEA is trying to address here with its sleek e-bike that could take you anywhere within a distance of 60 to 70km, aided by a powerful electric motor of 250Watt that could get you a total pedal-assisted range up to 45mi/72km per charge.

The e-bike also features an easy rechargeable system to its removable in-frame lithium-ion battery pack that takes about five hours to recharge, as well as a Shimano transmission that provides six different driving modes.

Should it prove successful, IKEA’s FOLKVÄNLIG e-bike must also come in a foldable variant, which gives the market even more room for growth.

Create a Lasting Impression for your Business

A business card provides essential information about an individual or company. A business card not only provides details but acts as a lasting impression of the individual or company because the card is the only thing that the client/customer has to remember the meeting by. This means having a well designed and professional business card is vitally important.

The most widely used type of business card is a paper card, these cards however present problems. The paper card is likely to be torn or ripped and can even smudge when they get wet. If these problems occur and the recipient can’t make out the contact information written on the card, then the card automatically loses its value and becomes worthless. Networking and growing business contacts is very important, so why risk it all in a flimsy card that is likely to be broken or even thrown away.

Why not invest in something meaningful and reliable to represent your business?

2 boysShanghai Metal Corporation (SMC) offers a range of stainless steel business cards, which enables those problems to be completely avoided.
