Flanging is a fast and efficient means of fastening sheet or sheet metal panels together. It involves the use of flanges – thin strips of metal with protruding ‘teeth’ along one edge – to secure two sheets or panels together. A flanging machine is required to perform the process.
The process works by bending both sheets of metal into the desired shape, making sure that the teeth of one sheet fit into the slots in the other. Once in place, a flanger – a tool consisting of a rotating disc with a protruding wheel – is passed along the length of the joint. As it rolls along it ‘flanges’ the sheets together, forming a secure bond.
It is important that the teeth of the flange and the slots of the receiving panel are evenly aligned before using this tool. To achieve a tight fit, additional pressure may need to be applied with a hammer or flanging tool after the flanger has been applied. This is known as ‘flanging & hammering’ and it ensures that the joint remains tight and secure.
Flanging is a widely used and simple method of fastening materials, making it an ideal choice for many projects. It’s popularity is due to its speed, affordability and strength – it is far stronger than riveting, in fact. It can be used to join sheets and panels of various materials and thickness, however, the most common use is to join thin sheets and panels, such as those made from aluminum, copper and brass.
Flanging can be used in many different applications, including shipbuilding, automobile manufacturing, construction, and even furniture and ornamentation. It is versatile and easy to use, making it a practical choice for many industries.
The process is particularly useful for connecting two pieces of metal that lie at an angle to each other – such as the side of a boat or the corner of a wall – as it ensures a tight, secure fit. It is also effective for joining curved pieces of metal, as long as the flanges fit neatly into the slots.
In conclusion, flanging is a practical, cost effective and efficient means of fastening metal sheets and panels together. With its versatility and relative ease of use, it is no wonder that it is such a popular choice for a range of industries – from boat building to furniture construction. With the help of a flanging machine and the application of extra pressure where necessary with a hammer or flanging tool, a secure and safe fit can be achieved in no time.
