It is a precision tooling component, and its condition is directly reflected in product surface quality, dimensional consistency, and startup stability. A small scratch on a die lip, hardened residue left in a flow area, or a sealing face damaged during cleaning can become a repeated problem in every meter of extrusion that follows.<\/p>\n\n\n\n<p>This is why <strong>extruder die maintenance<\/strong> should never be treated as an afterthought. Many recurring die lines, startup marks, contamination issues, and unnecessary troubleshooting cycles are not caused by poor production control alone. In many cases, they begin <strong>after the run is over<\/strong>\u2014when the die is removed, cleaned too aggressively, stored carelessly, or reinstalled without a proper check.<\/p>\n\n\n\n<p>If your team already has a routine inspection system, this article should be read as the next step after those checks. Daily and weekly inspections help you find problems early. But once a die comes off the line, it needs a separate handling process to keep it from becoming the source of the next defect. <a href=\"https:\/\/jfextruder.com\/extrusion-line-maintenance-checklist\/\" data-type=\"post\" data-id=\"2740\">[Daily, Weekly, and Monthly Maintenance Checklist for Extrusion Machines]<\/a><\/p>\n\n\n\n<p>And if you want a deeper technical explanation of why die condition matters so much in the first place, it is also worth reviewing how die geometry and surface quality influence melt flow and final product quality.

The first rule is to remove residue <strong><a href=\"https:\/\/www.nordson.com\/en\/about-us\/nordson-blog\/polymer-processing-systems-blogs\/2023-04-06-cleaning-your-extrusion-die\" target=\"_blank\" rel=\"noopener\">without changing the die surface<\/a><\/strong>.<\/p>\n\n\n\n<p>This sounds obvious, but many avoidable tooling problems begin during rushed cleanup. Steel screwdrivers, hard scrapers, wire brushes, and other overly aggressive tools may remove residue quickly, but they can also leave scratches, rounded edges, dents, or damaged sealing faces. Those small marks may later show up as die lines, surface streaks, contamination hang-up points, or sealing problems during the next run.<\/p>\n\n\n\n<p>For that reason, the standard rule should be simple:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Never use hard steel tools on critical die surfaces<\/li>\n\n\n\n<li>Never treat polished flow surfaces like rough mechanical hardware<\/li>\n\n\n\n<li>Never assume a visible scratch is only cosmetic<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Use the right cleaning tools<\/h3>\n\n\n\n<p>A safe die-cleaning toolkit usually includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Brass or copper brushes<\/li>\n\n\n\n<li>Brass or copper scrapers<\/li>\n\n\n\n<li>Wooden scrapers<\/li>\n\n\n\n<li>Hard plastic cleaning tools where appropriate<\/li>\n\n\n\n<li>Non-woven cloths or clean industrial wiping cloths<\/li>\n\n\n\n<li>Compressed air used with care<\/li>\n\n\n\n<li>Suitable die cleaning compounds or approved heated cleaning methods where required<\/li>\n<\/ul>\n\n\n\n<p>The principle behind these tools is straightforward: the cleaning tool should be softer than the die steel so it cannot damage precision surfaces. This matters especially around die lips, polished melt-contact surfaces, transitions, and sealing faces.<\/p>\n\n\n\n<p>It is also important to establish good handling discipline during disassembly. Cleaned parts should not be placed on dirty benches, rough steel tables, or random shop surfaces where contact damage can happen immediately after cleaning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A practical die cleaning SOP after the run<\/h3>\n\n\n\n<p>Once the die has been removed from the line, cleaning should follow a controlled sequence rather than a rushed tear-down.<\/p>\n\n\n\n<p><strong>1. Remove residue while it is still manageable<\/strong><\/p>\n\n\n\n<p>In many cases, residue is easiest to remove when it is still warm enough to be soft or leathery rather than fully hardened. Waiting too long can make residue removal more difficult and increase the temptation to use force.<\/p>\n\n\n\n<p>At this stage, the goal is not perfect finishing. The goal is to remove the bulk of the remaining polymer carefully, without gouging any critical surface. Use brass, copper, wood, or other approved soft tools. Work slowly around corners, lips, and recessed areas. Do not force tools into areas where you cannot clearly control the contact angle.<\/p>\n\n\n\n<p><strong>2. Disassemble and clean part by part<\/strong><\/p>\n\n\n\n<p>Do not treat the die as one dirty block that needs brute-force scraping. Clean each part in a controlled way. Keep matching components organized. Protect cleaned pieces from contact damage while the remaining pieces are still being worked on.<\/p>\n\n\n\n<p>This part-by-part approach matters because many dies are damaged not during production, but during uncontrolled teardown\u2014parts stacked together, pieces laid on rough surfaces, bolts mixed with precision faces, or cleaned components left exposed while other work continues.<\/p>\n\n\n\n<p>For stubborn or heavily carbonized residue, some factories use approved heated cleaning methods\u2014such as a controlled cleaning oven or burn-off system\u2014followed by careful manual finishing. These methods should be selected based on the tooling material, residue type, and internal shop procedure, not used as a one-size-fits-all shortcut.<\/p>\n\n\n\n<p><strong>3. Adapt the cleaning approach to the material that was last run<\/strong><\/p>\n\n\n\n<p>This is where real shop-floor discipline matters. Not all residues behave the same way, and not all materials should be approached with the same cleaning logic.<\/p>\n\n\n\n<p><strong>PE and PP residues<\/strong><\/p>\n\n\n\n<p>PE and PP residues often soften and release more easily than some higher-temperature or more sensitive materials. However, if shutdown was poorly managed and material sat too long at heat, carbonized or degraded residue may remain in corners or low-flow areas. In that case, the risk is not only leftover plastic, but later contamination release.<\/p>\n\n\n\n<p><strong>PVC residues<\/strong><\/p>\n\n\n\n<p>PVC requires more caution. If residue has been overheated or left sitting too long, it can degrade more aggressively and become harder to remove safely. Delayed cleaning also increases the chance that the die will later show corrosion-related problems or contamination during the next startup. When PVC has been run, post-run die cleaning should be treated with more urgency and more care.<\/p>\n\n\n\n<p><strong>Engineering plastics and higher-temperature materials<\/strong><\/p>\n\n\n\n<p>Some engineering plastics or higher-temperature materials can cling more strongly, leave tougher residue, or make operators more likely to over-scrape during removal. That raises the risk of surface damage. In these cases, patience and approved cleaning methods matter even more than speed.<\/p>\n\n\n\n<p>The practical point is this:<\/p>\n\n\n\n<p><strong>A cleaning procedure should always consider what material was last processed.<\/strong> A generic &#8220;scrape everything until it looks clean&#8221; approach is exactly how good tooling gets damaged.<\/p>\n\n\n\n<p><strong>4. Finish with inspection, not routine polishing<\/strong><\/p>\n\n\n\n<p>This is a critical rule.<\/p>\n\n\n\n<p>The final step of routine die cleaning should be <strong>inspection<\/strong>, not routine polishing.<\/p>\n\n\n\n<p>It may be tempting to treat light hand polishing as a normal finishing step, but this is risky language for an SOP. Operators may interpret it as permission to &#8220;improve&#8221; lips, polished surfaces, or sealing areas casually. That can alter the very geometry the die depends on.<\/p>\n\n\n\n<p>Instead, the correct finish to routine cleaning is to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Visually inspect all critical surfaces<\/li>\n\n\n\n<li>Check die lips carefully<\/li>\n\n\n\n<li>Inspect corners, recesses, transitions, and flow-contact areas<\/li>\n\n\n\n<li>Confirm sealing faces are clean and not visibly damaged<\/li>\n\n\n\n<li>Remove loose debris before storage<\/li>\n\n\n\n<li>Document any suspected damage before the die is put away<\/li>\n<\/ul>\n\n\n\n<p>If critical surfaces appear scratched, chipped, rounded, or otherwise damaged, that is no longer a routine cleaning issue. That is a repair evaluation issue.<\/p>\n\n\n\n<p>At that point, the right question is not &#8220;Can someone touch this up quickly?&#8221; The right question is &#8220;Will this damage affect flow, sealing, or product quality?&#8221;<\/p>\n\n\n\n<p>For the corresponding equipment-side cleaning procedure covering the screw and barrel, see our companion guide on extruder screw and barrel cleaning. <a href=\"https:\/\/jfextruder.com\/clean-extruder-screw-and-barrel\/\" data-type=\"post\" data-id=\"2790\">[How to Clean an Extruder Screw and Barrel: When to Purge, When to Tear Down, and How to Avoid Recurring Contamination]<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Store the die so it does not get damaged while not in use<\/h2>\n\n\n\n<p>A die can be perfectly cleaned and still be ruined in storage.<\/p>\n\n\n\n<p>This is why <strong>die storage<\/strong> must be treated as part of <strong>extruder die maintenance<\/strong>, not as a separate afterthought. Once a die is clean, it becomes vulnerable in a different way. The risks shift from polymer residue to corrosion, moisture exposure, airborne contamination, accidental impact, part mix-up, and poor handling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dry the die fully before protection<\/h3>\n\n\n\n<p>Do not rush directly from cleaning to wrapping.<\/p>\n\n\n\n<p>Before a die is protected for storage, it should be fully cleaned and dry. Trapped moisture under oil, wrapping, or protective material can create the kind of hidden damage that only gets discovered later\u2014usually during startup, when time pressure is highest.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Apply corrosion protection where appropriate<\/h3>\n\n\n\n<p>A clean die surface should be protected with a suitable rust inhibitor or anti-rust oil where appropriate for the tooling type, storage duration, and workshop environment. The goal is not to drench the die carelessly, but to protect exposed precision surfaces from oxidation while the die is out of service.<\/p>\n\n\n\n<p>This is especially important if your shop has humidity fluctuations, seasonal condensation risk, or long storage intervals. For broader seasonal maintenance and humidity-control considerations, refer to your seasonal extrusion maintenance procedures. <a href=\"https:\/\/jfextruder.com\/preventive-maintenance-for-extrusion-lines\/\" data-type=\"post\" data-id=\"2759\">[Preventive Maintenance for Extrusion Lines: What to Adjust for Heat, Humidity, and Dust]<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Protect critical surfaces from contact damage<\/h3>\n\n\n\n<p>Many tooling problems are created not by corrosion, but by accidental contact.<\/p>\n\n\n\n<p>A die lip does not need much force to be damaged. A polished face does not need much impact to be marked. A machined sealing surface does not need much mishandling to lose the surface integrity needed for reliable reassembly.<\/p>\n\n\n\n<p>For that reason:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Protect die lips from direct contact<\/li>\n\n\n\n<li>Do not allow bare metal-to-metal impact between tooling components<\/li>\n\n\n\n<li>Use soft protective wrapping or protective separators where appropriate<\/li>\n\n\n\n<li>Do not stack dies carelessly<\/li>\n\n\n\n<li>Do not leave cleaned tooling exposed on open benches or on the floor<\/li>\n<\/ul>\n\n\n\n<p>A die should never be treated like general steel stock. It is a precision production asset.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Label and store the die in a controlled location<\/h3>\n\n\n\n<p>Good storage is not only physical protection. It is also traceability.<\/p>\n\n\n\n<p>Each stored die should be clearly identified so the team can quickly confirm:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Die number or die code<\/li>\n\n\n\n<li>Product or application<\/li>\n\n\n\n<li>Last used material if relevant<\/li>\n\n\n\n<li>Last cleaning date or maintenance status<\/li>\n\n\n\n<li>Any note about known damage, caution, or pending repair evaluation<\/li>\n<\/ul>\n\n\n\n<p>Store the die on a stable, dedicated rack or in another controlled location where it is protected from impact, dirt, and unplanned handling. Do not leave it directly on the floor. Do not mix unmatched components. Do not create a situation where the next operator has to guess which condition the die was left in.<\/p>\n\n\n\n<p>When storage is handled well, the die remains production-ready. When storage is handled badly, the next startup inherits the damage.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"404\" src=\"https:\/\/jfextruder.com\/wp-content\/uploads\/2026\/03\/Extruder-die-storage-and-pre-installation-inspection-showing-anti-rust-protection-labeled-rack-storage-and-surface-condition-checks.webp\" alt=\"Extruder die storage and pre-installation inspection showing anti-rust protection, labeled rack storage, and surface condition checks\" class=\"wp-image-2816\" srcset=\"https:\/\/jfextruder.com\/wp-content\/uploads\/2026\/03\/Extruder-die-storage-and-pre-installation-inspection-showing-anti-rust-protection-labeled-rack-storage-and-surface-condition-checks.webp 600w, https:\/\/jfextruder.com\/wp-content\/uploads\/2026\/03\/Extruder-die-storage-and-pre-installation-inspection-showing-anti-rust-protection-labeled-rack-storage-and-surface-condition-checks-300x202.webp 300w, https:\/\/jfextruder.com\/wp-content\/uploads\/2026\/03\/Extruder-die-storage-and-pre-installation-inspection-showing-anti-rust-protection-labeled-rack-storage-and-surface-condition-checks-18x12.webp 18w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Check the die before reinstalling it<\/h2>\n\n\n\n<p>A die should not go back onto the line simply because it looks &#8220;clean enough.&#8221;<\/p>\n\n\n\n<p>The period just before reinstallation is the final checkpoint in the whole maintenance chain. It is the point where the team confirms whether cleaning and storage were actually successful\u2014or whether new risks were introduced while the die was offline.<\/p>\n\n\n\n<p>Before reinstalling the die, the team should check for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Visible rust or staining<\/li>\n\n\n\n<li>Dust, debris, or leftover protective material<\/li>\n\n\n\n<li>Signs of impact damage<\/li>\n\n\n\n<li>Scratches on visible critical areas<\/li>\n\n\n\n<li>Residue remaining in corners, lips, or melt-contact areas<\/li>\n\n\n\n<li>Sealing-face condition<\/li>\n\n\n\n<li>Completeness of matching components, inserts, fasteners, and related parts where applicable<\/li>\n<\/ul>\n\n\n\n<p>This check should be calm and deliberate. It is much cheaper to stop and correct a tooling issue before startup than to discover the problem through scrap, repeated marks, contamination, or unstable production afterward.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Know when the die has moved beyond routine maintenance<\/h3>\n\n\n\n<p>This boundary is important.<\/p>\n\n\n\n<p>Routine maintenance covers cleaning, protection, storage, and pre-installation verification. It does <strong>not<\/strong> automatically include geometry correction on critical areas.<\/p>\n\n\n\n<p>If the die shows any of the following, the issue should be escalated for qualified repair evaluation rather than improvised hand correction:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Damage to die lips<\/li>\n\n\n\n<li>Visible scratches on polished flow surfaces<\/li>\n\n\n\n<li>Compromised sealing faces<\/li>\n\n\n\n<li>Recurring product marks that remain after proper cleaning<\/li>\n\n\n\n<li>Repeated startup contamination that suggests trapped residue or damage<\/li>\n\n\n\n<li>Deformation, impact damage, or questionable alignment condition<\/li>\n<\/ul>\n\n\n\n<p>This is where many factories lose tooling life unnecessarily. A small defect is treated casually, someone attempts a quick hand fix, and the result becomes a larger quality problem than the original damage.<\/p>\n\n\n\n<p>The safer rule is simple:<\/p>\n\n\n\n<p><strong>Do not let routine maintenance turn into unqualified die repair.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Good die maintenance reduces future troubleshooting<\/h2>\n\n\n\n<p>One of the most practical reasons to improve <strong>die maintenance procedure<\/strong> is that it reduces false troubleshooting later.<\/p>\n\n\n\n<p>When die cleaning and storage are handled poorly, the next defect often appears in production and gets blamed on the wrong cause. Teams may start adjusting output, temperatures, cooling, line speed, or haul-off behavior when the actual issue is a scratched lip, trapped residue, or a sealing surface damaged during handling.<\/p>\n\n\n\n<p>This is also why die-related defects should connect naturally to your troubleshooting content. If the product shows die lines, repeated surface marks, startup contamination, or damage-like streaks, poor post-run die handling should be considered as a possible root cause. <\/p>\n\n\n\n<p>Likewise, if daily or weekly inspections identify buildup, wear, or die-related concern, the correct next step is not just &#8220;watch it more closely.&#8221; It is to follow a controlled post-run handling and maintenance path. <a href=\"https:\/\/jfextruder.com\/extrusion-line-maintenance-checklist\/\" data-type=\"post\" data-id=\"2740\">[Daily, Weekly, and Monthly Maintenance Checklist for Extrusion Machines]<\/a><\/p>\n\n\n\n<p>In that sense, good die maintenance does not only protect the tool. It protects the clarity of your diagnostic process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion: protect the die between runs, and it will protect quality during the next run<\/h2>\n\n\n\n<p>Good <strong>extruder die maintenance<\/strong> is not about doing more work. It is about doing the right work at the right moment.<\/p>\n\n\n\n<p>A die should be cleaned carefully, not aggressively. It should be stored protectively, not casually. It should be checked before reuse, not assumed ready by appearance alone.<\/p>\n\n\n\n<p>When factories follow this discipline, they reduce avoidable die lines, startup defects, contamination issues, and repeated troubleshooting. They also extend tooling life and keep more of the die&#8217;s original performance intact over time.<\/p>\n\n\n\n<p>The most important takeaway is this:<\/p>\n\n\n\n<p><strong>Many die-related defects are created between runs, not during the run itself.<\/strong><\/p>\n\n\n\n<p>If your die is already causing repeated lines, startup marks, or contamination after cleaning, the most useful next step is to review not only the die condition itself, but also how it was last handled, cleaned, stored, and reinstalled.<\/p>\n\n\n\n<p>If you need support evaluating a die that is already showing repeat defects, send the product type, material, defect photos, and recent die handling history.

There is no fixed interval; the frequency depends on the material processed, product surface sensitivity, and how aggressively the previous run left residue behind.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q2: Why are brass or copper tools safer than steel tools for die cleaning?<\/strong><\/h3>\n\n\n\n<p>Brass and copper are softer than the hardened steel used in most extrusion dies. That means they can dislodge residue without scratching or deforming die lips, polished flow surfaces, or sealing faces. Steel tools may solve one immediate cleaning problem while creating a longer-term tooling problem.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q3: Does PVC residue require extra caution during die cleaning?<\/strong><\/h3>\n\n\n\n<p>Yes. PVC residue that has been overheated or left sitting too long can degrade aggressively, become harder to remove, and increase the risk of corrosion-related problems or startup contamination later. When PVC has been run, the die should be cleaned promptly\u2014before residue hardens\u2014and with particular attention to corners and low-flow areas where degraded material tends to collect.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q4: How long can a die stay in storage before it needs to be checked again?<\/strong><\/h3>\n\n\n\n<p>Any die that has been stored for more than a few weeks should be re-inspected before reuse, even if it was properly cleaned and protected. The longer the storage period and the less controlled the environment, the more important it becomes to verify rust protection, surface condition, cleanliness, and the completeness of matched parts before reinstallation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q5: When should a die be sent for professional repair instead of cleaned in-house?<\/strong><\/h3>\n\n\n\n<p>A die should be evaluated for qualified repair when it shows lip damage, scratches on polished flow surfaces, compromised sealing faces, repeated product marks that persist after proper cleaning, or recurring startup contamination that suggests trapped residue or structural tooling damage. These issues are beyond the scope of routine maintenance and should not be addressed with informal shop-floor touch-ups.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u041e\u0437\u043d\u0430\u043a\u043e\u043c\u044c\u0442\u0435\u0441\u044c \u0441 \u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u043e\u0439 \u0446\u0435\u043f\u043e\u0447\u043a\u043e\u0439 \u043f\u043e\u0441\u043b\u0435\u043f\u0440\u043e\u0434\u0430\u0436\u043d\u043e\u0433\u043e \u043e\u0431\u0441\u043b\u0443\u0436\u0438\u0432\u0430\u043d\u0438\u044f \u044d\u043a\u0441\u0442\u0440\u0443\u0437\u0438\u043e\u043d\u043d\u043e\u0439 \u0433\u043e\u043b\u043e\u0432\u043a\u0438: \u043e\u0447\u0438\u0441\u0442\u043a\u0430 \u0431\u0435\u0437 \u043f\u043e\u0432\u0440\u0435\u0436\u0434\u0435\u043d\u0438\u044f \u043f\u043e\u0432\u0435\u0440\u0445\u043d\u043e\u0441\u0442\u0438, \u0445\u0440\u0430\u043d\u0435\u043d\u0438\u0435 \u0441 \u0437\u0430\u0449\u0438\u0442\u043e\u0439 \u043e\u0442 \u043a\u043e\u0440\u0440\u043e\u0437\u0438\u0438 \u0438 \u043f\u0440\u043e\u0432\u0435\u0440\u043a\u0430 \u043f\u0435\u0440\u0435\u0434 \u0443\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u043e\u0439, \u043f\u0440\u0435\u0434\u043e\u0442\u0432\u0440\u0430\u0449\u0430\u044e\u0449\u0430\u044f \u0434\u0435\u0444\u0435\u043a\u0442\u044b, \u043a\u043e\u0442\u043e\u0440\u044b\u0445 \u043c\u043e\u0436\u043d\u043e \u0438\u0437\u0431\u0435\u0436\u0430\u0442\u044c \u043f\u0440\u0438 \u0437\u0430\u043f\u0443\u0441\u043a\u0435.<\/p>","protected":false},"author":1,"featured_media":2809,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[7],"tags":[55,23],"class_list":["post-2807","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-maintenance-support","tag-extrusion-dies","tag-maintenance"],"taxonomy_info":{"category":[{"value":7,"label":"Maintenance &amp; Support"}],"post_tag":[{"value":55,"label":"Extrusion Dies"},{"value":23,"label":"Intent: Maintenance"}]},"featured_image_src_large":["https:\/\/jfextruder.com\/wp-content\/uploads\/2026\/03\/Extruder-die-maintenance-workflow-showing-die-cleaning-protected-storage-and-pre-installation-inspection.webp",600,316,false],"author_info":{"display_name":"Jason","author_link":"https:\/\/jfextruder.com\/ru\/author\/admin\/"},"comment_info":0,"category_info":[{"term_id":7,"name":"Maintenance &amp; Support","slug":"maintenance-support","term_group":0,"term_taxonomy_id":7,"taxonomy":"category","description":"Minimize downtime with actionable maintenance checklists and troubleshooting protocols.
