Various <a href=\"https:\/\/info.formfedern.com\/en\/manufacturing-techniques-form-springs-flat-springs-and-leaf-springs\/\" target=\"_blank\" rel=\"noopener\">manufacturing processes<\/a> such as laser cutting, punching, wire erosion, CNC punching and bending centers and a wide variety of forming processes are used. The basic principle of the flat spring and shaped spring is based on the elastic deformation of the spring steel, whereby energy is absorbed under load and released again when the load is removed.<\/p>\n<p>The key difference between classic flat springs and modern form springs lies in their geometric complexity. While traditional flat springs usually have simple, rectangular geometries, shaped springs can realize almost any contours and three-dimensional structures. This design freedom makes it possible to combine several functions in a single component while making optimum use of the available installation space.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Constructive_possibilities_and_design_freedom\"><\/span>Constructive possibilities and design freedom<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The design of flat springs and shaped springs offers exceptional variety. Not only can the desired spring properties be determined through targeted shaping, but additional functions can also be integrated. For example, a flat spring or shaped spring can be designed in such a way that it simultaneously functions as a force, guide, fastening element and electrical contact. Integrated fastening lugs, stops, contact surfaces or guide elements make the flat spring and shaped spring an all-rounder and significantly simplify design and assembly. This design freedom makes the form spring and flat spring ideal components for multifunctional and optimized designs.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Calculation_approaches_and_design\"><\/span>Calculation approaches and design<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><a href=\"https:\/\/info.formfedern.com\/flachformfeder-berechnung\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-2028\" src=\"https:\/\/info.formfedern.com\/wp-content\/uploads\/Flachformfeder_Berechnung-300x156.jpg\" alt=\"Flat form spring Calculation\" width=\"400\" height=\"208\" data-wp-pid=\"2028\" srcset=\"https:\/\/info.formfedern.com\/wp-content\/uploads\/Flachformfeder_Berechnung-300x156.jpg 300w, https:\/\/info.formfedern.com\/wp-content\/uploads\/Flachformfeder_Berechnung.jpg 600w, https:\/\/info.formfedern.com\/wp-content\/uploads\/Flachformfeder_Berechnung-385x200.jpg 385w, https:\/\/info.formfedern.com\/wp-content\/uploads\/Flachformfeder_Berechnung-200x104.jpg 200w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a>The design of an optimum flat spring or shaped spring requires many years of sound practical experience. Especially with the individual and complex shape of the form spring, a standardized design by <a href=\"https:\/\/info.formfedern.com\/flachformfeder-berechnung\/\" target=\"_blank\" rel=\"noopener\">calculating bending radii<\/a> and bending stresses is only possible to a limited extent. The design of a form spring is therefore carried out iteratively with a strength and functional verification, often with the support of CAE software with finite element analyses. For this reason, Gutekunst Formfedern documents design-relevant information for subsequent designs and calculations in detail for each production run.<\/p>\n<p>The stress concentration at corners and transitions deserves special attention during design. These critical areas often determine the service life of the entire metal spring. A sophisticated design with optimum bending radii and transitions as well as well thought-out force transmission to the flat spring and shaped spring can prevent dangerous stress concentrations.<\/p>\n<p>The right <a href=\"https:\/\/info.formfedern.com\/en\/application-of-spring-steel-sheets-and-surface-treatments\/\" target=\"_blank\" rel=\"noopener\">choice of material<\/a> for the respective application plays a decisive role. Whether for high or low temperatures, corrosive or aggressive ambient media, food-safe, medically pure or electrically conductive applications. There are high-quality spring steel grades and subsequent surface treatments that offer high reliability for the respective application.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Manufacturing_technologies_and_quality_assurance\"><\/span>Manufacturing technologies and quality assurance<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-906 alignright\" src=\"https:\/\/info.formfedern.com\/wp-content\/uploads\/\/Laserschneiden_Edelstahl_Trumpf-300x169.jpg\" alt=\"Laser cutting\" width=\"401\" height=\"225\" data-wp-pid=\"906\" srcset=\"https:\/\/info.formfedern.com\/wp-content\/uploads\/Laserschneiden_Edelstahl_Trumpf-300x169.jpg 300w, https:\/\/info.formfedern.com\/wp-content\/uploads\/Laserschneiden_Edelstahl_Trumpf-200x112.jpg 200w, https:\/\/info.formfedern.com\/wp-content\/uploads\/Laserschneiden_Edelstahl_Trumpf.jpg 600w, https:\/\/info.formfedern.com\/wp-content\/uploads\/Laserschneiden_Edelstahl_Trumpf-356x200.jpg 356w\" sizes=\"auto, (max-width: 401px) 100vw, 401px\" \/>Modern production technologies enable the precise manufacture of flat springs and shaped springs. Depending on the requirements, shape and quantity, the finished stamping and bending process is used for large series as well as the separate cutting and bending process for small and medium series. In addition to classic laser cutting, water jet cutting is also used for thicker materials and wire erosion for thin and delicate parts. CNC-controlled bending centers and automatic bending machines as well as individual bending and forming tools are used for subsequent forming. There are no limits to the design of shaped springs.<\/p>\n<p>Final surface treatments such as vibratory grinding, barrel finishing, phosphating, burnishing, galvanizing, painting and many more are offered as well as the pressing in of threaded bolts, for example, or direct installation in assemblies provided. In addition to standard spring strip steels and spring steel sheets, numerous stainless steels, non-ferrous metals and non-ferrous metals are offered in strip or plate form for the production of flat springs and shaped springs.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Variety_of_applications_in_practice\"><\/span>Variety of applications in practice<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Flat springs and shaped springs made from flat material can be found in almost all areas of industry. In the automotive industry, they are used as contact springs in electronic systems, as clamping springs for fastenings, as sensor elements in measuring systems or as complex actuating springs in switching mechanisms. Their compact design makes them ideal for modern, compact applications in vehicle construction.<\/p>\n<p>Electrical engineering uses the precise electrical properties for contact applications.
