FAQ

  • Q What are the processes involved in sheet metal fabrication?

    A
    There is a wide range of different processes that make up the sheet metal fabrication process, depending on the required outcome but the most commonly used are:
    Sheet metal folding whereby a machined called a press brake applies tonnage of pressure to the sheet to achieve a desired angle.
    Sheet metal laser cutting is used to profile a flat metal sheet. The required shape is “nested” onto the sheet using cnc programming and the ultra-high temperature laser machines follows the specified path, piercing through the metal sheet as it goes to leave a cut out shape. Waste sheet metal skeleton is then recycled.
    Sheet metal can also be perforated, profiled and formed through a process called punching in which a tool is forced through the sheet at high velocity, causing a perforation. A cnc punch machine will hit the sheet in this way repeatedly at high speed to create the desired pattern.
    Sheet metal components are often welded once all other processing has been completed. Components are joined together to form larger assembly’s through a process of MIG, TIG, spot or even robot welding.
  • Q Which machines are used for sheet metal fabrication?

    A
    Sheet metal fabrication is often a high volume, repeat process whereby hundreds or thousands of the same product are required, meaning that the same process will be repeated sheet after sheet.
    For this reason, the machinery that is used must be:
    1. Extremely accurate. Many of the products produced in the sheet metal fabrication process are designed to extremely tight tolerances. If a laser cut profile is a fraction of a millimetre wrong, then the rest of the processing will be inaccurate and ultimately the end product wont work.
    2. High Speed. With many thousands of components being processed every day, speed is of the essence as parts are moved quickly around the factory from one processing area to the next. Sheet metal fabrication machines must be able to produce parts at a rapid pace, with no loss of accuracy.
    3. Automated. Increasingly, automation in sheet metal fabrication is key as it allows for reduced human input in processing, more accuracy and efficient and efficiency in part production and importantly, 24 hour lights out operation. At CNCT, we have integrated fully automated machinery into many of our sheet metal fabrication processes including robotic welding and robotic folding.
  • Q Which products are made from the sheet metal fabrication process?

    A
    Sheet metal fabrication contributes to more everyday items than you might think, from your kettle and toaster, to your PC, car, and home appliances.
    At CNCT, we produce products for a wide range of sectors including electrical, rail, automotive, aviation, retail, and many, many more.
  • Q Which materials can be processed?

    A
    There are many different metals that can be made into sheet metal, such as aluminium, brass, copper, steel, tin, nickel and titanium. Most commonly however, steel, stainless or aluminium sheet metal is chosen for its properties.
  • Q Is sheet metal fabrication expensive?

    A
    As a high-volume production service, prices for sheet metal fabrication depend on batch size and repeatability. As quantities increase, generally prices will drop as costs in machine set up, programming and tooling are spread over more components.
    Price will also depend on the complexity of a product and the number of processes required to create it. For example, a simple laser cut component may be relatively inexpensive when compared to a complex assembly which my have 4-5 different processes and a large amount of assembly time.
  • Q What is sheet metal laser cutting?

    A
    Sheet metal laser cutting is a process that uses a high-powered laser beam to cut through sheet metal materials. The laser beam is directed onto the surface of the sheet metal, which causes the material to melt or vaporize. The laser follows a predetermined path, guided by computer software, to cut out the desired shapes or designs.
     
    The laser cutting process offers several advantages over traditional cutting methods. Firstly, it allows for a high level of precision and accuracy, ensuring clean and sharp edges. It can cut intricate designs and complex shapes with ease, providing flexibility in design possibilities.
     
    Additionally, laser cutting is a fast and efficient process. The laser beam can move at high speeds, resulting in quicker production times compared to other cutting methods. It also reduces the need for additional finishing processes, as the laser cutting process often leaves smooth and polished edges.
     
    Moreover, laser cutting is a versatile method that can be used on a wide range of sheet metal materials, including stainless steel, aluminum, brass, and copper. The ability to cut various materials makes it suitable for different industries, such as automotive, aerospace, electronics, and more.
     
    Overall, sheet metal laser cutting offers a reliable and precise method for producing high-quality parts and components. It provides efficient production times, versatility in design options, and the ability to work with a variety of materials.
