In practice, it is <strong>four different levels<\/strong>, and only the last one needs a new die. Most projects that ask for a custom profile are actually asking for level two or three, and can be supplied in days rather than weeks.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2026\/08\/A065-Dimension-drawing.jpg\" alt=\"Dimension drawing of HL-A065, a stock section\" title=\"\"><figcaption class=\"wp-element-caption\">A stock section: channel, aperture and groove already fixed \u2014 level 1 to 3 changes are possible.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What actually counts as custom?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Four levels, ordered by how much they change:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Level<\/th><th>What changes<\/th><th>Needs a new die?<\/th><\/tr><\/thead><tbody><tr><td>1. Cut to length<\/td><td>Nothing \u2014 the bar is cut<\/td><td>No<\/td><\/tr><tr><td>2. Finish or cover<\/td><td>Anodize\/powder coat, PC \/ PMMA \/ lens<\/td><td>No<\/td><\/tr><tr><td>3. Modification of an existing section<\/td><td>Additional machining, holes, slots, a modified cover groove<\/td><td>No, or a die correction<\/td><\/tr><tr><td>4. New section<\/td><td>Wall thickness, channel, aperture, geometry<\/td><td><strong>Oui<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The confusion comes from quoting all four as &#8220;custom&#8221;. A buyer asking for black powder coat and 1,730 mm lengths is not asking for a new die, and should not be quoted on a die timeline.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How much time does each level add?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is where the trade is actually made, and the difference between levels is large.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Level 1 \u2014 cut to length.<\/strong> Stock profiles come in any length up to 4 m. Cutting is a day&#8217;s work inside a normal order cycle; our stock items ship in about 3 to 5 days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Level 2 \u2014 finish or cover.<\/strong> Anodizing and powder coating are batch processes, so the wait depends on when the next batch in that colour runs. A standard colour may add days; a non-standard one waits for a batch to accumulate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Level 3 \u2014 modification.<\/strong> Machining an existing section is scheduled around production, not before it. It adds days rather than weeks, but it cannot be pulled forward without a reason.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Level 4 \u2014 new die.<\/strong> Die design, cutting, trial, correction and approval, then production. Our custom lead time is 15 to 30 working days depending on complexity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical reading: <strong>levels 1\u20133 are measured in days, level 4 in weeks.<\/strong> If a project is in a schedule crunch, the useful question is not &#8220;how fast can you make a die&#8221; but &#8220;which level do we actually need&#8221;.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2026\/09\/HL-A086-Dimension-drawing.jpg\" alt=\"Section drawing of HL-A086 showing a thin-walled channel\" title=\"\"><figcaption class=\"wp-element-caption\">HL-A086 \u2014 thin walls and a tight channel. A die like this is what a new tool would have to reproduce.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">When is a new die worth it?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Three cases where it is the right answer rather than a reflex:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The section genuinely does not exist.<\/strong> A specific aperture, a wall thickness the catalogue does not offer, an integrated fixing feature. If the drawing cannot be satisfied by any existing profile, a die is the answer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The volume justifies it.<\/strong> A die is a one-off tool carried by the order. On a repeat programme it fades into the unit; on a single small batch it is the whole item.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Part consolidation.<\/strong> A custom section that integrates a mounting flange, a cable channel, and a cover groove replaces three catalogue parts and the labour required to assemble them. That is often the real argument for a die, and it is about assembly time rather than the profile.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does a die lock you into?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the part that does not appear in a lead-time discussion, and it is the more expensive one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The section is fixed.<\/strong> Once the die exists, the geometry is what it is. A change to the channel or the aperture means a die correction, and a correction takes the same order of time as the original tool.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The supply is single-source.<\/strong> A custom section can only be made on that die, by whoever holds it. There is no second supplier to switch to if a schedule slips.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The specification hardens early.<\/strong> Everything downstream \u2014 cover, end caps, connectors, fixing \u2014 is designed around that section. Changing one of them later may mean changing all of them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So a die is not just a longer lead time at the start. It is a narrower set of options for the rest of the project.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do you avoid over-specifying?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most common failure is not a wrong die \u2014 it is a die that was not needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Four questions before drawing anything new:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Which existing section is closest?<\/strong> Start from the catalogue and work outward, not the reverse.<\/li>\n\n\n\n<li><strong>What exactly is wrong with it?<\/strong> Often it is one dimension \u2014 the aperture is 2 mm narrow, or the wall is 0.2 mm thin. That may be a level-3 modification rather than a new die.<\/li>\n\n\n\n<li><strong>Could the cover solve it?<\/strong> A different diffuser changes the light line more than a 1-mm change in aperture does.<\/li>\n\n\n\n<li><strong>What is the real constraint \u2014 the section or the detail?<\/strong> Sometimes the profile is blamed for a slot that was cut to the wrong depth.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Every question that is answered &#8220;the existing section is fine&#8221; removes weeks from the programme.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What can be changed without a die?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">More than most buyers assume:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Longueur<\/strong> \u2014 any cut length within the bar stock.<\/li>\n\n\n\n<li><strong>Finish<\/strong> \u2014 anodized, powder coated, in standard or matched colours.<\/li>\n\n\n\n<li><strong>Cover<\/strong> \u2014 clear, frosted, opal, prismatic, or a lens, where the section takes more than one.<\/li>\n\n\n\n<li><strong>End caps and connectors<\/strong> \u2014 options within the accessory family for that section.<\/li>\n\n\n\n<li><strong>Machining<\/strong> \u2014 holes, slots, cable entries, cutouts, drilled or milled after extrusion.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">What cannot be changed without a die: the channel width, the aperture, the wall thickness, and the cover groove geometry. Those four are the section, and the section is the die.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2026\/08\/A043-Dimension-drawing.jpg\" alt=\"Dimension drawing of HL-A043 with its cover groove called out on the section\" title=\"\"><figcaption class=\"wp-element-caption\">HL-A043 section \u2014 the cover groove is part of the die, so the cover follows the section.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What about covers and accessories on a custom section?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">They follow the section, which is the point most schedules miss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A new section needs its own cover profile \u2014 the groove geometry is part of the die, so an existing cover will not fit a new body unless the groove was drawn to match one. That means the cover is also a custom item, with its own trial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">End caps and connectors are tooled for the section too. On a stock profile they exist; on a new one they are made after the die is proven, which puts them behind the extrusion rather than in parallel with it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical consequence: <strong>budget the accessories into the same schedule as the die.<\/strong> A project that plans for the extrusion and then asks for caps is a project that waits twice.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do you brief it?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Send four things and the question of level usually answers itself:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The drawing or a sketch with dimensions<\/strong> \u2014 channel width, aperture, wall thickness.<\/li>\n\n\n\n<li><strong>The strip<\/strong> \u2014 PCB width and watts per meter.<\/li>\n\n\n\n<li><strong>The fixing<\/strong> \u2014 how the body is held, and to what.<\/li>\n\n\n\n<li><strong>The quantity and the date<\/strong> \u2014 because volume is what decides whether a die is economically sensible, and the date decides whether it is even possible.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Our <a href=\"\/fr\/led-profiles\/\" target=\"_blank\">range<\/a> is 219 sections, which is a large starting point for step one. If none of them is close, the <a href=\"\/fr\/service-process\/\" target=\"_blank\">service process page<\/a> sets out how a custom run proceeds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can a custom section be delivered faster than 15 days?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, when the change is small enough to be a die correction rather than a new die, and the production queue allows it. It is worth asking rather than assuming, but it should not be planned for.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is there a minimum order for a custom profile?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and it is set by the die rather than by the profile \u2014 a new die needs enough volume to be worth cutting. Discuss the quantity early, because it may move the answer from level four to level three.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I get samples before committing to a die?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For an existing section, yes \u2014 a cut length is a normal sample. For a new die, a trial length off the first run is the usual step, and it comes after the die is cut rather than before.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How does a custom profile affect repeat orders?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The second order carries no die work, so it moves on a normal production schedule. That is where a custom section becomes comparable to stock: the one-off sits on the first run, not on every run.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I mix stock and custom in one project?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and it is often the sensible answer: stock sections for the runs that are standard, a custom section only where the detail demands it. The schedule then depends solely on the custom item, which is easier to plan around.<\/p>\n<style>\r\n.lwrp.link-whisper-related-posts{\r\n            \r\n            \r\n        }\r\n        .lwrp .lwrp-title{\r\n            \r\n            font-size: 20px;\r\n        }.lwrp .lwrp-description{\r\n            color: #5b5757;\r\n            \r\n\r\n        }\r\n        .lwrp .lwrp-list-container{\r\n        }\r\n        .lwrp .lwrp-list-multi-container{\r\n            display: flex;\r\n        }\r\n        .lwrp .lwrp-list-double{\r\n            width: 48%;\r\n        }\r\n        .lwrp .lwrp-list-triple{\r\n            width: 32%;\r\n        }\r\n        .lwrp .lwrp-list-row-container{\r\n            display: flex;\r\n            justify-content: space-between;\r\n        }\r\n        .lwrp .lwrp-list-row-container .lwrp-list-item{\r\n            width: calc(50% - 20px);\r\n        }\r\n        .lwrp .lwrp-list-item:not(.lwrp-no-posts-message-item){\r\n            \r\n            \r\n        }\r\n        .lwrp .lwrp-list-item img{\r\n            max-width: 100%;\r\n            height: auto;\r\n            object-fit: cover;\r\n            aspect-ratio: 1 \/ 1;\r\n        }\r\n        .lwrp .lwrp-list-item.lwrp-empty-list-item{\r\n            background: initial !important;\r\n        }\r\n        .lwrp .lwrp-list-item .lwrp-list-link .lwrp-list-link-title-text,\r\n        .lwrp .lwrp-list-item .lwrp-list-no-posts-message{\r\n            \r\n            font-size: 18px;\r\n            font-weight: 400;\r\n            \r\n        }@media screen and (max-width: 480px) {\r\n            .lwrp.link-whisper-related-posts{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-title{\r\n                \r\n                \r\n            }.lwrp .lwrp-description{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-list-multi-container{\r\n                flex-direction: column;\r\n            }\r\n            .lwrp .lwrp-list-multi-container ul.lwrp-list{\r\n                margin-top: 0px;\r\n                margin-bottom: 0px;\r\n                padding-top: 0px;\r\n                padding-bottom: 0px;\r\n            }\r\n            .lwrp .lwrp-list-double,\r\n            .lwrp .lwrp-list-triple{\r\n                width: 100%;\r\n            }\r\n            .lwrp .lwrp-list-row-container{\r\n                justify-content: initial;\r\n                flex-direction: column;\r\n            }\r\n            .lwrp .lwrp-list-row-container .lwrp-list-item{\r\n                width: 100%;\r\n            }\r\n            .lwrp .lwrp-list-item:not(.lwrp-no-posts-message-item){\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-list-item .lwrp-list-link .lwrp-list-link-title-text,\r\n            .lwrp .lwrp-list-item .lwrp-list-no-posts-message{\r\n                \r\n                \r\n                \r\n                \r\n            };\r\n        }<\/style>\r\n<div id=\"link-whisper-related-posts-widget\" class=\"link-whisper-related-posts lwrp\">\r\n            <h3 class=\"lwrp-title\">Articles connexes<\/h3>    \r\n        <div class=\"lwrp-list-container\">\r\n                                            <div class=\"lwrp-list-multi-container\">\r\n                    <ul class=\"lwrp-list lwrp-list-double lwrp-list-left\">\r\n                        <li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/fr\/case-study\/hl-a003-case\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">HL-A003 \u2014 Ceiling Corner Linear Profile Case Study<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/fr\/company-news\/guide-to-ceiling-lighting-with-led-profiles\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">Guide de l'\u00e9clairage de plafond avec des profil\u00e9s LED<\/span><\/a><\/li>                    <\/ul>\r\n                    <ul class=\"lwrp-list lwrp-list-double lwrp-list-right\">\r\n                        <li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/fr\/how-to\/choosing-the-right-led-diffuser\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">Choisir le bon diffuseur \u00e0 LED : Ce qu'il faut savoir, Qu'est-ce qu'un diffuseur \u00e0 LED Les diffuseurs \u00e0 LED sont essentiels \u00e0 l'optimisation de la qualit\u00e9 de l'\u00e9clairage dans divers environnements, y compris les zones r\u00e9sidentielles, commerciales et industrielles.
