Yes, You Can Generate Cheap Electricity!

It’s incredible just how much technology has evolved over the past decade. With the advent of technology, our way of life has changed drastically. Free energy generators are one of the biggest and latest blessings of the progression in technology. Gone are the days when you had to rely on the power company to provide you with electricity to power your homes and appliances. Nowadays you can generate the same electricity at your home without having to pay for it ever! Honest! But the question that comes to your mind is why should you try out a free energy generator, when you already have an electricity connection, right?

Are you aware of the procedure used by power companies for the production of electricity? Tens of thousands of tons of coal are burnt every single day to power your home by these power companies and the quantity of pollution this creates is best left to your imagination. Such an act leads to global warming, harmful effects on the environment and shortens life span of living things. Can you live with the guilt?

Do you want to live with the guilt of destroying the planet when instead of taking alternate routes to stop that happening in the first place? Other alternatives such as free energy generator which were not only more environmentally friendly but provided you with absolutely free electricity as well!

Now you don’t want to be that person do you? The answer is quite obvious. And after you’ve heard about the incredible benefits that you stand to gain by using free energy generator, I’m sure you’ll change your mind. First of all you need to realize the many free energy generator options that you have nowadays. I am certainly not referring to gas or petrol generators as they obviously do not produce free electricity.

Free energy generators can be divided into four broad types. Each of these types have their own advantages and disadvantages and the selection of which free energy generator you should choose basically depends on your electricity needs and whether the free energy generator in question, can work effectively in your dwelling.

Hydropower generator- The term hydro stands for water in Greek. For electricity to be generated using hydropower generators, water is required. Now, hold on there, it’s not like you’re going to fill the generator up with water and watch as it produces electricity. Electricity is generated by hydropower generators when fast moving water flows through it. Should your house be next to a fast flowing river, you can surely use this type of a free energy generator to produce electricity. When a hydropower generator comes in contact with fast flowing water, its turbines turn which results in generation of electricity that can be used to run appliances in your house. But the biggest problem with this type of free energy generator is that, not many people have streams of rivers running nearby their houses. That is why this option is not ideally recommended for everybody

Wind power generators- As the name suggests this free electric generator type depends on the force of the wind to produce electricity. Wind power generators are made of three blades that resemble a fan which spin when wind gushes through them. The best place for to install a wind power generator is either a balcony or your rooftop. When wind gushes through the blades, it creates a spin which in turn produces electricity. These free electric generators type requires almost no maintenance but the issue with this type of free electric generator is that if you live in a city or an area where there are no strong winds, then the amount of electricity that you would generate would be limited. In case you live in an area that has many barriers to wind such as high rise buildings, it would be better for you to turn to other free electric generator options.

Magnetic generators- Now we come to my preferred type of free electric generator, the magnetic generator. Now most of you out there must be thinking that how can magnets be used to generate electricity right? I had the same feeling until I came across this little guide that changed my life; Magnets4Energy. I’m normally not the kind who goes for these kind of products, as I’m apprehensive of being scammed but on the claim of some friends of mine, and after reading a review about magnets 4 energy ( ) , I tried out this neat little guide and was pleasantly surprised at the outcome. Magnets4energy has helped me build a magnetic generator that has sharply reduced my electricity bills. Before making my final decision as to whether I should try or leave the product, I decided to look for relevant information on the internet to help in making this decision. It was a true shocker for me to know that people were already taking advantage of this blessing. Trains called Maglev also rely on magnetism for power! In Japan, these trains have been known to clock speeds of up to 500 Km per hour. But the best thing about these magnetic generators is that they do not need any special conditions in which to operate. These are not reliant on water, wind or sunshine. The procedure for constructing a magnetic generator is thoroughly covered in guides such as the Magnets4Energy! You are now ready to produce free energy without causing any damage to the environment!

By now I’m sure you’ve understood the numerous benefits of using a free electric generator and just why you should think about using them. Go for the choice that suits you best and take the initiative in keeping this planet a safe and healthy for all of its Marc Foster

What is Sheet Metal Fabrication?

The processes and techniques of shaping and bending sheet metals to create a variety of components are known as sheet metal fabrication. All sorts of sections and complex shapes can be given to the sheet metals. All products that contain any metal components will be required to proceed through some type of sheet metal fabrication. Many manufacturing fields such as computer, medical, appliances, or electronics often use this metal fabrication process.

Processes of Sheet Metal Fabrication

Different processes such as forming, cutting, and finishing are used in order to reach the final product in sheet metal fabrication.


To fabricate a sheet metal at first it has to be cut into different shapes. Then the pieces are modeled or shaped into final pieces.
Shearing and electrical discharge machining are some of the cutting processes in shearing bigger pieces which are sheared into much thinner pieces. The operation of shear stress on a cutting machine will be needed for this process. In EDM conductive materials will then be melted from an electrode spark which comes from a small fully charged electrode that will be surrounded by iodized water.

Different tools like electrical powered shears and tin snips are often used for cutting sheet metals. Computer based equipments like Computer Numerical Control Punch Press or Computer Numerical Control Lasers may also be used. Tin snips is a hand tool that is required and used on a daily basis by a variety of companies. Electrical powered shears is often used and functional by the help of a battery powered electric motor. It has a crank drive and movable cutting blade for properly cutting sheets of metals. Next a laser light will be pressed across the surface of the metal sheet in order to cut in Computer Numeric Control lasers cuts. In order to cut the metal into different sizes or shapes like square, hexagon and circle the Computer Numerical Control Punch Press will need to be used. Water jets can be used to cut sheet metal as well. It uses the high pressure water ranging from twenty thousand to sixty thousand psi in order to cut the metal properly. It doesn’t generate any type heat while its being used for cutting which is an important factor.


After cutting the metal sheet, it has to be shaped into its required shape to create a component and this process is known as forming. It refers to the variety of ways that are used to shape sheet metal into a variety of forms. While forming a metal sheet take care of the ductility, ability of the sheet metal to allow it to be manipulated without fracturing.

Rolling, shape flat pieces of metal over and over by the use of roll stands, Bending and forming, hand based process used to get the desired shape on the sheet metal, Punching, used to punch holes in the metal, Welding, used to join pieces of sheet metal together, Stamping, tools and dies are used to stamp designs into the metal, Hardware and fastener creation methods, used to add latches or handles to the sheet metal, are the processes of forming sheet metal.


Every sheet metal goods have to go through the process of finishing to eliminate or to polish rough spots and edges.
After going through all of these processes we find finished sheet metal goods.

Now-a-days, with the advancement of technology, many of these techniques are now applied with the use of computer controlled machinery. Instead of opening a factory to create their own metal products, a company might hire a sheet metal fabrication specialist to do the work for them. This gives the company more time to focus on marketing and promotion and can also save money.

Sheet metal work and Its Types

By: Stuart Small

By: Stuart Small

The formation of sheet metal, thin and flat pieces metals of varying thicknesses is known as sheet metal work. Different types of sheet metal works include:

  • Deep drawing

  • Cutting

  • Perforating

  • Spinning

  • Press brake forming

  • Roll forming

  • Rolling

  • Stamping

  • Bending

  • Ironing

  • Wheeling

  • Decambering

Deep drawing

Drawing process where the depth of the part being made is more than half its diameter is known as deep drawing. In this process, metal blank is stretched around a plug then make it move into a die, a molding cutter. Kitchen sink is a perfect example of deep drawing technology. Aerospace, automobile, dairy, lighting, pharmaceuticals, and plastics are the industries that are rely on deep drawing process.


To give the sheet metals different shapes it has to be cut into tiny pieces. To cut sheet metals various tools from hand tools to very large powered shears are used. CNC (Computer Numerical Control) and Lasers cutting or multi-tool CNC punch press are the most modern sheet metal cutting processes.


Perforating is used to design, produce, and fabricate metal to meet the precise specification. Perforated metal offers a solution that is both decorative and functional.


Spinning, performed by hand or by a CNC lathe, is the process in which a disk or tube of metal is rotated at high speed and formed into an axially symmetric part. The process has both artisans and commercial applications. To produce architectural detail, specialty lighting, decorative household goods and urns artisans use the process and among its commercial application include rocket nose cones, cookware, gas cylinders, brass instrument bells, and public waste receptacles.

Press brake forming

In need of a metal housing for a particular part, brackets for machines and equipments, metal framing, and even decorative touches press break forming is used. It is considered as an ideal solution for those who are in need of replacement parts, large numbers of brackets, and fastening solutions as well as prototypes for almost any type of machinery.

Roll forming

The process includes a large strip of metal to be passed through continuous sets of rolls, or stands to collect the needed cross-section profile. For producing parts with long lengths or in large quantities it is an ideal process. The process of roll forming is a simpler one.


In this process a metal sheet is passed through a pair of rolls. On the basis of the shape of the final product rolling is classified into two classes-- Flat, shape of the product is either classed as sheet or plate, and Profile rolling, the final product may be a round rod or other shaped bar. Hot rolling and cold rolling are the two types of rolling according to the temperature of the metal rod.


Punching by using a machine press or stamping press, blanking, embossing, bending, flanging, and coining are the different operations that are associated with stamping. This is both a single stage and a multiple stage operation.


Process in which a metal is deforming plastically to change its shape is known as bending. In this process one axis of the material is deformed not the surface area of the material. Press breaks are usually used for bending. As a flexible process it is used for getting different shapes.


The process of uniformly thinning the work piece in a specific area is known as ironing in the metal sheet forming.


To use English Wheel to form smooth, compound curves from flat sheets of metal is known as wheeling.


The process of removing camber, or horizontal bend, from strip shaped materials is known as decambering. Flattening or leveling processes resemble in decambering.
