Metal bending is exactly as it sounds – a process in which sheet or plate metal is bent into a different shape to render it suitable for its intended end purpose. Though it is possible to bend metal manually, bending machines are often used to create accurate and repeatable bends, reducing waste and lowering the cost of production.
Important things to note about metal bending
The radius of the bend must be equal to or greater than the thickness of the metal being bent as too small a radius can result in quality issues such as weakening or cracking once in use.
Materials will typically spring back after bending, returning partly towards their original form and this must be accounted for when planning the final shape. This is a particular issue with stainless steel and other high-strength alloys, so when working with these materials, it is often necessary to overcompensate to account for springback.
Bending machines such as those offered by https://www.cotswold-machinery-sales.co.uk/euromac-bending-machines/horizontal-bending-machines/ deliver a consistent force based upon the strength and thickness of the material and the bend length and radius.
Choosing a bending machine
It is important to select a bending machine that will deliver the outcomes you are seeking, for example, if you need to make straight, repetitive bends, then a horizontal machine will deliver the best results, while if you are making boxes, a box and pen folder is more appropriate.
By understanding the fundamentals of material selection, bend radius and springback, you will be well prepared to select an appropriate bending machine for your metal fabrication business.
