There are various fabrication processes in the sheet metal industry, which are oftentimes used in combination with one another. The methods can be either one or more of the following: metal stamping, cutting, casting, welding, and extrusion. These fabrication techniques are executed to highlight the metal’s properties and showcase its flexibility in application.
Sheet metal punching is a common fabrication process used sheet metal manufacturing. Punching is a cutting process that involves applying sufficient cutting force to a sheet of metal to remove a section of material.
In the past, metal punching was performed solely with manually operated machines. However, today’s punching methods are performed using advanced machines, which are programmed to punch standard or specially designed shapes in metal.
Computer Aided Design (CAD) software was created in the late 1960’s to accelerate the engineering drawing process. While CAD was historically used in engineering, drawing and construction architecture, it is now widely used for creating metal fabrication designs, and has superseded the time-consuming process of manually creating technical drawings.
While steel is more resistant than iron to some forms of degradation, there is an aspect of steel that can limit its long-term lifespan, which is the low level of corrosion resistance it offers. Steel holds a thin layer of oxide and if exposed to water and air for prolonged periods of time it can become damaged and considered impracticable and unusable in areas where corrosion is prominent.
Over the last 10 years, we have seen great technological advances in press brake machines. Thanks to numerous innovations, including the incorporation of Computer Numerical Control (CNC), Australian sheet metal manufacturing has become more efficient, less time consuming, and has been able to remain competitive with international markets.
There are many different types of welding that can be used to join and shape metal materials. This includes MIG, TIG, and spot welding, among others. Knowing how to perform each different type of welding allows us to ensure we get the best possible weld each time. Spot welding is most commonly used to to join or combine two or more sheets of metal, making it a highly valuable welding technique to master.
Computer Numerical Control (CNC) laser cutting is a sheetmetal fabrication process which relies on a concentrated laser beam, which is used to cut or engrave metal, with high precision or accuracy. Controlled through computer software, these powerful lasers can create any desired shape or pattern by burning, melting or vaporising parts of the metal material.
