Fabrication is generally one of the earliest parts of a metalwork project. A mistake at this stage can have implications for later stages, such as assembly and finishing, by which point it will not be easy to repair it. It can also be expensive. That is why it is important to ensure it is done correctly.
Materials
Your choice of materials is one of the most important aspects of your project, both in terms of the quality of the product and the likely costs. Stainless steel is more expensive than aluminium, which is more expensive than carbon steel in terms of raw cost but cheaper in manufacturing cost. Treatment, coating or plating may allow you to achieve the effect you want whilst using a smaller and therefore less costly amount of metal. The size and thickness of the metal will also be relevant. Standard and stock sizes are another way to save money.
Simplification
Another cost-saving approach that can make your life easier is ensuring you simplify your folds and bends. Keep bends as similar in size and direction as possible to reduce the need for adjustments during the process. For folds, the radius should not be smaller than the thickness of the metal. Try to avoid small bends unless you are using thin parts, as they are less effective with larger pieces.
Tolerances
Many beginners overdo the tight tolerance call-outs in their projects, including surfaces and features that are not essential to its overall functioning. This includes aspects such as distances, radii and any holes. Every unnecessary extra makes the piece more complex and more expensive, even for experts such as those at dkmsheetmetal.co.uk/, who may help orchestrate your sheet metal fabrication. It will take longer to produce, and there is a higher probability that it will end up needing to be scrapped.
The fabrication process can be complex, with many opportunities for things to go wrong, but following the advice of those with relevant expertise can help you ensure the best possible outcome whilst keeping your costs at a reasonable level.
