Sheetal Metal Fabrication Process
The choice of material for a sheet metal fabrication project can have a significant impact on the final cost. This is due to a number of factors, including the initial cost of the tooling required for each part and the raw material itself. This is particularly true for custom parts that require a significant amount of labour and skill to create.

One of the first considerations is the type of metal to use. This is largely determined by the performance requirements of the end product. For example, a part for an aeronautics application might prioritize weight and strength over other factors, while a structural steel part may prioritize yield or tensile strength over weight or corrosion resistance.
Once the raw materials have been selected, the process of cutting and bending can begin. Cutting can be done using a number of techniques, including laser beam cutting and plasma cutting. Each technique provides advantages and disadvantages depending on the specific metal being used, its thickness, and the type of cutting required. For instance, laser cutting is a good option for thinner metals, while plasma cutting is better suited to thicker material gauges.
How Does the Choice of Material Impact the Sheetal Metal Fabrication Process?
Following the cutting stage, bending can be used to reshape the sheet metal into its final form. This is a complex operation that requires skilled labour and specialised machinery to be carried out successfully. Bending can be used to create large contours in the metal, but is also effective for smaller ones. For example, a small bend radius can help to reduce the size of a component, which can save space or allow it to fit into a tighter spot.
Another important step in the fabrication process is welding. This involves the use of a high-powered electric arc to melt the base metals together. This creates a metallurgical bond that helps to strengthen the part and prevent it from rusting or becoming brittle in the future. There are many different welding techniques available, but the most common are MIG and TIG welding.
The finishing stage of the production process can also affect cost. The type of finish will depend on the product, but it can have an impact on both aesthetics and the strength of the finished part. For example, a powder coat can make the metal more resistant to corrosion or electricity, but it can also weaken it significantly.
When designing a new sheet metal product, it is essential to keep these factors in mind. By ensuring that the design is manufactured with manufacturability in mind, the team can avoid costly mistakes and ensure that the final part performs well for its intended lifecycle.
