href=\"https:\/\/info.formfedern.com\/en\/leaf-spring-calculation\/\">leaf springs<\/a>. These include the selection of the spring type, the specific spring shape, the choice of material, the determination of the dimensions as well as the consideration of the installation situation and the options for production and testing. The most important tools for these decisions are <a href=\"https:\/\/info.formfedern.com\/flachformfeder-berechnung\/\">calculations of the deformation behavior <\/a>of the springs. As there are usually more than two spring parameters to be determined, the basic design is carried out in an iterative process. A <a href=\"https:\/\/info.formfedern.com\/flachformfeder-berechnung\/\">functional and strength verification<\/a> must also be carried out for each designed spring. This involves checking whether the required spring rate, forces and travel are within the specified tolerances.<\/p>\n<p>When determining the spring geometry, manufacturing and material-related aspects must be taken into account in addition to the functional requirements in order to make production as efficient and cost-effective as possible. The design of <a href=\"https:\/\/info.formfedern.com\/en\/overview-of-spring-types\/\">metal springs<\/a> therefore requires special knowledge and experience in the areas of cold forming and <a href=\"https:\/\/info.formfedern.com\/federstahl-haerten\/\">heat treatment<\/a>. After all, the geometry of the spring not only determines its reliability, but often also the functionality of the entire product in which it is used.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Manufacturing\"><\/span>Manufacturing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Flat springs, shaped springs and leaf springs are manufactured according to requirements, shape and quantity using the pure bending \/ <a href=\"https:\/\/info.formfedern.com\/en\/properties-stamped-bent-parts\/\">stamping and bending process<\/a> or by <a href=\"https:\/\/info.formfedern.com\/en\/laser-cutting-and-laser-cutting-manufacturing-process-and-other-cutting-methods\/\">laser cutting<\/a> with subsequent <a href=\"https:\/\/info.formfedern.com\/en\/lasering-punching-forming-and-assembling\/\">forming<\/a> by bending, stamping and edging.
