They are the result of a combination of technical reasons, which are, however, linked to the commercial needs that the market imposes on spring manufacturers.<\/p>\n<h5>HOW WE FACE THE CHALLENGE<\/h5>\n<p>At the moment the real challenge is: \u201c<strong>To produce the best spring at the best price<\/strong>\u201c. But we are also sure that the following issues are discussed every day by every spring manufacturer:<\/p>\n<ul>\n<li>How is it possible to make sure that a spring will work correctly, before it actually begins to work?<\/li>\n<li>How can we be sure that a particular spring is really capable of sustaining the working life cycle for which it was designed?<\/li>\n<\/ul>\n<p>The fields of use of springs are extremely wide and varied. One of the typical examples of very severe use, is that of springs used inside internal combustion engine valves, where in addition to being subjected to millions and millions of cycles, the springs must also be able to withstand high temperatures, which could cause the so-called \u201ctempering\u201d phenomenon.<\/p>\n<p>In order to obtain these very high mechanical performance levels consisting of correct deflection and continuous endurance of cycles with very high unit loads, the spring manufacturer must use special steel alloys containing vanadium, silicon, and other alloying elements, to ensure high yield strength. All this without forgetting the importance of\u00a0<strong>correct heat treatment<\/strong>, aimed at increasing both hardness and yield strength.<\/p>\n<p>In spite of the high-quality levels required by the customers, due to the highly critical mechanical aspects, the springs must be produced quickly and at low cost. All this makes \u201cthe spring component\u201d an extremely delicate element.<\/p>\n<p>It follows that the quality control of springs is crucial to ensure that the customer receives a product that fully meets their needs, trying to eliminate, or at least minimize, faults in the final product, which will be sold and used in everyday life.<\/p>\n<\/div><\/section><br \/>\n<section  class='av_textblock_section av-lf6p0tjh-c8c9f276e6dd04e3e7b0dd7352951846 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2><strong>THE BENEFITS OF PERFORMING DYNAMIC FATIGUE TESTS<\/strong><\/h2>\n<p>For more than 35 years, Easydur has specialized in the construction of measuring equipment. It therefore has a wealth of experience in the mechanical testing of springs of all kinds. Based on this know-how, we strongly believe that, today more than ever, it is imperative to carry out\u00a0<strong>long duration cyclical tests (Fatigue)<\/strong>\u00a0designed to simulate the behaviour of the spring during its \u201clife\u201d cycle.<\/p>\n<p>Dynamic fatigue tests on springs are often underestimated, and basically conceived as destructive tests, since most of the testing machines used for this purpose are mechanical instruments with very poor technological content, and without load cells and control software (the so-called \u201ccrank-handle system\u201d).<\/p>\n<p>These machines have the objective of applying stress to several springs of the same type, until one or more of them break, identifying only the number of \u201cblows\u201d that led to the breaking of a spring. It is not possible to set loads and, more importantly, it is not possible to detect the load drop moment during the cycles.<\/p>\n<p><strong>Identifying the relaxation and consequent loss of elastic characteristics of the springs<\/strong>\u00a0is an important time saver, and actually allows the springs to be characterized in a correct manner.<\/p>\n<p>It begs the question:\u00a0<strong>Why wait to reach breaking point, when the object could be achieved much sooner by detecting the relaxation?<\/strong><\/p>\n<p>During the last year, we have sold several machines specifically designed to allow our customers to perform dynamic fatigue tests, controlled by our specific \u201c<strong>EasyDynamics<\/strong>\u201d software, which allows to quickly, correctly and effectively simulate a life cycle of the tested springs, making the research and development of new production solutions much easier.<\/p>\n<p>It is important to be able to produce charts as a function of different physical measuring parameters (<strong>Force, Position, Time, Speed, Temperature, etc.<\/strong>)<\/p>\n<\/div><\/section><\/p><\/div><div  class='flex_column av-pnwpb-5d3349712ca06ed6f281b1d35f22fcab
