style=\"font-size: 1.5rem\">Challenges Faced by the Customer<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">\nAn automotive bumper manufacturing plant was promoting a productivity improvement project.<br \/>\nWithout additional investment in existing facilities, the plant began by focusing on increasing the number of bumpers they fed into the painting line to shorten cycle time and raise output.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">To achieve this, the spacing between bumpers waiting on the painting line was significantly reduced from 1,500 mm to 500 mm, causing an unexpected problem.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Because the bumpers were now positioned much closer to each other, <span style=\"font-weight:bold\">overspray from the paint-spraying robot reached the next bumper waiting for a different color<\/span>, contaminating the surface and causing coating defects.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/02\/nozzle-auto-001-image_01.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><br \/>\nPreviously, the spacing between waiting bumpers was 1,500 mm.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/02\/nozzle-auto-001-image_02.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><br \/>\nReducing the spacing to 500 mm resulted in overspray reaching the next bumper awaiting painting.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">To address this issue, the customer approached IKEUCHI\u2014known for its extensive lineup of air nozzles\u2014to explore measures such as an air curtain to block overspray.<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div

disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">IKEUCHI promptly visited the site to review the painting line and utility conditions.<br \/>\nThe conveyor was 1,800 mm wide and compressed air was available, so we proposed the <a href=\"https:\/\/www.dry-fog.com\/en\/products\/noz-air-slnha-h\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">SLNHA-H<\/a> air slit nozzle, specifying a lightweight PVC version for easier installation.<\/p>\n<p><img decoding=\"async\"

\/>\nStainless-steel SLNHA-H shown (reference image). The nozzle used in this case is PVC.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Also known as an air knife, the slit nozzle discharges a laminar sheet of air through a 0.1 mm slit opening.<br \/>\nA custom-made nozzle with a 1,800 mm slit length, matching the conveyor width, was installed at a height that would not interfere with the bumpers and directed straight downward to <span style=\"font-weight:bold\">create an air curtain<\/span>.<br \/>\nThis configuration was proposed as an effective way to block overspray.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/02\/nozzle-auto-001-image_04.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><br \/>\nThe slit nozzle forms an air curtain that blocks the dispersion of paint mist.\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Benefits Achieved<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\"><span style=\"font-weight:bold\">The slit nozzle successfully blocked paint mist dispersion<\/span> as intended, enabling the customer to increase the number of bumpers fed into the painting line.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">IKEUCHI\u2019s nozzles continue to support customers in boosting productivity and maintaining consistent coating quality on the production floor.<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto;text-align:center;margin-top:3rem\"><iframe loading=\"lazy\" width=\"100%\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/CMHE3Crq0vI\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\"><\/iframe><\/div>\n<\/section>\n","protected":false},"featured_media":0,"template":"","cat_cases":[87],"tag_cases":[554,544,534],"acf":[],"_links":{"self":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/cases\/9101"}],"collection":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/cases"}],"about":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/types\/cases"}],"wp:attachment":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/media?parent=9101"}],"wp:term":[{"taxonomy":"cat_cases","embeddable":true,"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/cat_cases?post=9101"},{"taxonomy":"tag_cases","embeddable":true,"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/tag_cases?post=9101"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
