Sheet metal fabrication is a vital process in manufacturing industries, involving the shaping and forming of thin metal sheets into various components. From automotive parts to architectural elements, sheet metal fabrication plays a crucial role in countless products we use daily. A wide range of techniques are employed in this process, each with its unique advantages and applications. At DB Sheetmetals we offer a wide range of sheet metal fabrication services, including laser cutting, CNC punching, powder coating, press brakes, and welding.
Laser Cutting
Laser cutting is a high-precision process used to cut sheet metal into complex shapes. A powerful laser beam is directed onto the material, melting and vaporising it to create the desired cut. This method is ideal for intricate designs and can be used on a variety of materials, including stainless steel, aluminium, and mild steel.
CNC Punching
CNC punching is another method used to create holes and simple shapes in sheet metal. A CNC machine controls a punch that presses through the material, creating the desired holes or shapes. This process is efficient for large-scale production of parts with repetitive patterns.
Powder Coating
Powder coating is a durable and environmentally friendly finish for sheet metal. A dry powder coating is applied to the metal surface and then cured in an oven. This process creates a hard, protective coating that is resistant to corrosion, scratches, and fading.
Press Brakes
Press brakes are used to bend sheet metal into various shapes, such as angles, channels, and U-shapes. The metal is placed between a top and bottom die, and the machine applies pressure to bend the material to the desired angle. Press brakes are essential for creating components that require precise angles and shapes.
Welding
Welding is a process used to join two pieces of metal together by melting the edges and fusing them together. There are several different welding techniques, including MIG, TIG, and spot welding.
- MIG welding (Metal Inert Gas) uses a wire electrode that feeds into the weld pool, providing both filler metal and an electric arc. A shielding gas, such as argon or carbon dioxide, is used to protect the weld from oxidation.
- TIG welding (Tungsten Inert Gas) uses a non-consumable tungsten electrode to create an electric arc between the electrode and the workpiece. A shielding gas, such as argon or helium, is used to protect the weld.
- Spot welding is used to join two pieces of metal together at a specific point. Two electrodes are placed on the metal pieces, and an electric current is passed through them, melting the metal at the point of contact.
Each welding technique has its own advantages and is suitable for different applications. MIG welding is often used for large-scale production, while TIG welding is ideal for precise and high-quality welds. Spot welding is commonly used for joining thin sheets of metal.
