The amount of particulate matter is variable. At different engine loads, sometimes more, sometimes less residue is produced. Especially at high speeds, the amount of particles produced is enormous. An engine electronic system uses a sensor to control the pressure at which the exhaust air can flow into the particle filter. The pressure is measured at two points: In front of the filter and behind it. The pipe behind the filter that leads to the pressure sensor is called the &#8220;differential pressure pipe&#8221;. Which brings us to <strong>KOHLHAGE<\/strong> Automotive. Because these differential pressure lines are manufactured in Neuenrade. Recently, even on another production cell from WAFIOS.<\/p>\n<p>&#8220;In the past, our production lines were often individual pieces from special machine construction,&#8221; says Christoph Brink, head of technical planning at <strong>KOHLHAGE<\/strong> Automotive and also responsible for the &#8220;pressure lines&#8221; production area. &#8220;We have largely moved away from this approach. Today we primarily work with manufacturers who offer modular machine concepts. This helps us with internal production control and is safer when it comes to investment planning.&#8221;<\/p>\n<\/div><\/section><\/div>\n\n<style type=\"text\/css\"

This German supplier builds machines for spring production as well as for wire and tube bending and is an established partner at <strong>KOHLHAGE<\/strong>. For example, WAFIOS systems produce oil lines for a large German car manufacturer &#8211; 1.2 million units per year. The new plant directs the focus more towards flexibility rather than large quantities.<\/p>\n<p>&#8220;The production of a differential pressure line involves 5 individual steps for which we previously needed 2-3 different machines. The &#8220;new one&#8221; standardises the previous individual steps and is the basis for optimising the internal machining processes,&#8221; says Brink. &#8220;But we actually bought this WAFIOS for a completely different reason: We are now as flexible in the production of differential pressure lines as we always wanted to be. Every motor vehicle needs a differential pressure line &#8211; but always a different one. The connections at the ends are standardised, fortunately. But lengths and geometries differ. For us as a manufacturer, set-up times have therefore always been a challenge. Thanks to optimised tool combinations, we can produce up to 20 different articles without time-consuming mechanical set-up processes. Buffer times are eliminated and throughput times are shorter.<\/p>\n<p>This also brings us new customers. Because if a German manufacturer of sports cars only needs 2,000 lines per year, we can produce those too, in a short time and at reasonable cost.&#8221; Brink is pleased.<\/p>\n<\/div><\/section><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-3ab8on-ee502ff783892c0d951c91ea67764db7\">\n.flex_column.av-3ab8on-ee502ff783892c0d951c91ea67764db7{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-3ab8on-ee502ff783892c0d951c91ea67764db7 av_one_full  avia-builder-el-9  el_after_av_one_full  avia-builder-el-last  first flex_column_div av-zero-column-padding  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-ky8cpgwm-9b7ef3451da7e9bf6f8073082b1ac883\">\n.avia-image-container.av-ky8cpgwm-9b7ef3451da7e9bf6f8073082b1ac883 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-ky8cpgwm-9b7ef3451da7e9bf6f8073082b1ac883 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-ky8cpgwm-9b7ef3451da7e9bf6f8073082b1ac883 av-styling- avia-align-center  avia-builder-el-10  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-9151 avia-img-lazy-loading-not-9151 avia_image ' src=\"https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal.jpg\" alt='' title='Wafios frontal'  height=\"1259\" width=\"1889\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal.jpg 1889w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-300x200.jpg 300w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-1030x686.jpg 1030w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-768x512.jpg 768w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-1536x1024.jpg 1536w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-1500x1000.jpg 1500w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-705x470.jpg 705w, https:\/\/www.kohlhage.de\/wp-content\/uploads\/2022\/01\/Wafios-frontal-450x300.jpg 450w\" sizes=\"(max-width: 1889px) 100vw, 1889px\" \/><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>KOHLHAGE helps to make cars ecologically cleaner<\/p>\n","protected":false},"author":2,"featured_media":9154,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1,4],"tags":[],"class_list":["post-9171","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-personen","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/posts\/9171","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/comments?post=9171"}],"version-history":[{"count":2,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/posts\/9171\/revisions"}],"predecessor-version":[{"id":9173,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/posts\/9171\/revisions\/9173"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/media\/9154"}],"wp:attachment":[{"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/media?parent=9171"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/categories?post=9171"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.kohlhage.de\/en\/wp-json\/wp\/v2\/tags?post=9171"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
