What is sheet metal working? A simple guide from Linde Machines

Sheet metal working involves shaping, cutting and joining sheet metal to create parts used in industry, transport and construction. It can involve thin sheet metal parts of a few millimetres or thicker parts up to 25 mm, and the method is chosen based on what the part will be used for and how large the production is. 

Materials and thicknesses

Different materials have different processing requirements. Steel and stainless steel are often used where strength and durability are important, while aluminium is lighter and suitable for components where weight matters. Copper and brass are also used in some projects.  

Thicker sheet metal requires more powerful machines, such as hydraulic presses or automatic presses, while thinner sheet metal is often handled by laser cutting or press brakes. Choosing the right material and method is crucial for both precision and end result. 

Common methods in sheet metal working

There are several techniques used depending on the materials and needs: 

• Automatic pressing - suitable for large volumes and standard parts 

• CNC machining - high precision for detailed projects 

• Eccentric pressing - good for complex shapes 

• Hydraulic pressing - powerful for thicker sheet metal 

• Edging - shaping sheet metal to the right angle or profile 

• Laser cutting - clean, precise cuts with minimal rework 

• Assembly and finishing - finalising the components 

• Robotic welding - smooth and efficient welding 

Customisation for volume and needs

Sheet metal processing can be customised for both small and large series. Smaller volumes often go via laser cutting or press brake, while larger series are processed with automatic presses. The choice of method depends on the material, the details and the number of parts to be produced. 

History and uses of sheet metal working

sheet metal processing has a long tradition in industry and is central to many manufacturing processes. At Linde Maskiner, we have been working with sheet metal since 1853, and our components are used in more than half of Europe's heavy lorries. Sheet metal components are also found in machinery, electronics, building components and interior design, demonstrating the versatility of the technology. 

Quality and sustainability

Quality is always in focus. We follow standards such as IATF 16949, ISO 9001 and ISO 3834-2, and customise processes to meet specific customer requirements. At the same time, we strive to reduce environmental impact and use materials efficiently.
