Sheet metal fabrication is an important process that involves bending and shaping of the metal to give the desired shape to the sheet. This process is used in almost all industries to make various products. It can be used to create all complex hollow shapes and sections.
Sheet metal fabricators in Melbourne use a range of tools from simple tools to sophisticated power-operated automatic machinery. If the desired product is complicated, then it is made in parts and then assembled together.
The process mainly starts with cutting. Huge rolls of Melbourne sheet metal are cut into pieces with the help of cutting tools like hand scissor or laser cutter fro thin layers while power operated shears are used for heavier gauge materials.
The next process involves punching, which means making holes in the metal article with an appropriate tool and then removing the extra metal surrounding the part manufactured. Another type of fabrication is shaping. Folding and bending are two common processes used for giving shape to the sheet. Presses or similar machines are used in methods like grooving stamping, crimping and beading. They are mainly used to stiffen and shaping the metal, mainly for manufacturing of pipes, tubes and circular shaped parts.
Bending and folding is used for making angles and sections. A process called coiling is used to increase strength and provide a suitable edge. A roll-forming machine is used for making circular or cylindrical shapes such as tubes.
Cupping and embossing are common press forming techniques. Cupping meaning giving the sheet a desired shape (generally the final stage of fabrication) with the help of tools while embossing refers to a particular design used for strengthening purpose. It can be applied to semi-finished products as well.
The other techniques include flanging, stiffening, deep drawing, performing, flow forming and spinning, which are not so commonly used. Specialists in the field would give the desired output at a pocket-friendly price.
