This guide outlines how aerospace manufacturers can meet stringent NADCAP standards, select compliant equipment, and enable a Continuous <strong>aerospace composite curing process<\/strong> that passes audits on the first attempt.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.despatch.com\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Despatch<\/strong><\/a><strong> <\/strong>has built industrial ovens since 1902 and works with leading aerospace manufacturers, so the insights below reflect real audit expectations and shop\u2011floor realities.<\/p>\n\n\n\n<h2><strong>What is NADCAP and Why it Matters for Aerospace Suppliers?<\/strong><\/h2>\n\n\n\n<p><a href=\"https:\/\/www.p-r-i.org\/nadcap\" target=\"_blank\" rel=\"noreferrer noopener\">NADCAP (administered by PRI) <\/a>is the aerospace industry\u2019s consensus programme for special\u2011process accreditation. Instead of every OEM auditing you separately, a single PRI audit verifies that your process and equipment meet agreed criteria\u2014often a contractual requirement for flight hardware. Start at PRI\u2019s official NADCAP page, and use <a href=\"https:\/\/www.eauditnet.com\/eauditnet\/ean\/user\/login.htm\" target=\"_blank\" rel=\"noreferrer noopener\">eAuditNet\u2019s Qualified Manufacturers List (QML)<\/a> to benchmark what accredited peers are doing.<\/p>\n\n\n\n<h2><strong>Key Oven Requirements to Meet AMS2750 Pyrometry Requirements<\/strong><\/h2>\n\n\n\n<ul class=\"style-list\"><li><strong>Pyrometry discipline (AMS2750):<\/strong> Auditors check for AMS2750 pyrometry requirements\u2014covering SAT, TUS, and sensor calibration. Expect documented controls for temperature sensors, instrumentation classes, System Accuracy Tests (SAT), and Temperature Uniformity Surveys (TUS). AMS2750H (current) outlines these core elements and their intervals. Build your URS to reflect your OEM and Task Group expectations.<\/li><li><strong>Temperature uniformity:<\/strong> Define your required band across the work zone at relevant set\u2011points. Uniformity underpins void\u2011free laminates and repeatable resin cures. (Your OEM spec\u2014e.g., BAC5621\u2014may tighten uniformity and mapping rules.)<\/li><li><strong>Traceable data logging:<\/strong> Auditors will look for complete, tamper\u2011evident records\u2014setpoints, actuals, SAT\/TUS results, and batch identifiers\u2014exportable for review. PRI training materials emphasise this record\u2011keeping for audit success.<\/li><li><strong>Vacuum integrity and control (for OOA\/VBO):<\/strong> Out\u2011of\u2011autoclave curing uses vacuum bag\u2011only consolidation in a controlled oven. Specify stable vacuum with continuous monitoring and alarms over the full cure cycle.<\/li><\/ul>\n\n\n\n<h3><strong>Oven Features That Enable NADCAP-Compliant Aerospace Composite Curing<\/strong><\/h3>\n\n\n\n<p>Map the requirements above to concrete features when you evaluate equipment:<\/p>\n\n\n\n<ul class=\"style-list\"><li><strong>Airflow engineered for composites:<\/strong> Uniflow or custom airflow promotes even heat transfer to complex tools and lay\u2011ups, driving uniformity during ramps, soaks and cools.<\/li><li><strong>Integrated vacuum bagging systems:<\/strong> Multi\u2011port vacuum manifolds and jack panels support multiple parts and thermocouples with stable, logged vacuum throughout the cycle.<\/li><li><strong>Audit\u2011ready controls and reporting:<\/strong> A PC\u2011based process controller that sequences recipes, enforces limits, and auto\u2011generates batch reports simplifies NADCAP evidence collection.<\/li><li><strong>Walk\u2011in capacity for real parts:<\/strong> <a href=\"https:\/\/www.despatch.com\/walkin-ovens-and-truck-in-ovens.html\" target=\"_blank\" rel=\"noreferrer noopener\">Walk-in ovens for aerospace components<\/a> sized for full assemblies help you achieve uniform curing. Furthermore, they reduce the risk associated with piecemeal processing.<\/li><li><strong>Out of autoclave (OOA) composite curing capability:<\/strong> Has gained traction for cost efficiency while still meeting NADCAP compliant industrial oven requirements.<\/li><\/ul>\n\n\n\n<h2><strong>Questions to Ask Before Buying NADCAP Compliant Industrial Ovens<\/strong><\/h2>\n\n\n\n<ol><li><strong>Uniformity guarantee:<\/strong> What uniformity can you guarantee across my defined load volume and set\u2011points? Will you perform a witnessed TUS to confirm?<\/li><li><strong>Pyrometry alignment:<\/strong> How does the control\/instrumentation package support AMS2750 (sensor types, instrument classes, SAT\/TUS workflows)?<\/li><li><strong>Calibration &amp; traceability:<\/strong> Are calibrations and SAT\/TUS services available with ISO\/IEC 17025 accreditation where required by my spec\/OEM?<\/li><li><strong>Vacuum system details:<\/strong> How many vacuum\/pressure ports per wall, monitoring resolution, allowable leak rate, and stability over multi\u2011hour cures?<\/li><li><strong>Data &amp; reporting:<\/strong> Can I export encrypted, review\u2011ready batch reports with thermocouple maps, alarms, and operator actions?<\/li><li><strong>Scalability &amp; service:<\/strong> How quickly can capacity expand (additional ports, TC channels), and what global service coverage is available?<\/li><\/ol>\n\n\n\n<h2><strong>Despatch Walk-In Ovens for Aerospace Composite Curing<\/strong><\/h2>\n\n\n\n<p><strong>Despatch\u2019s composite curing ovens<\/strong> pair a custom walk-in design with multi-port vacuum systems and Focal Point\u2122 controls. The result? Tight temperature uniformity, full data traceability and NADCAP-ready performance.<\/p>\n\n\n\n<p>Our <strong>TAD\/TFD walk-in ovens<\/strong> handle large aerospace components with engineered airflow for consistent curing. For high-mix <strong>out-of-autoclave (OOA)<\/strong> work, Despatch configures TFD models with multiple thermocouple jacks, vacuum and pressure ports, all seamlessly managed by Focal Point\u2122.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<p class=\"flex-video\"><iframe loading=\"lazy\" title=\"Ovens for Processing Aerospace Components\" width=\"600\" height=\"338\" src=\"https:\/\/www.youtube.com\/embed\/obS0vLNIaN4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n\n<\/div><\/figure>\n\n\n\n<h2><strong>FAQs: NADCAP Ovens for Aerospace<\/strong><\/h2>\n\n\n\n<h3><strong>1. What does NADCAP require for composite curing ovens?<\/strong><\/h3>\n\n\n\n<p>NADCAP audits verify pyrometry compliance (AMS2750), temperature uniformity, vacuum control, and full traceable data logs.<\/p>\n\n\n\n<h3><strong>2. What is the difference between an autoclave and an out-of-autoclave (OOA) oven?<\/strong><\/h3>\n\n\n\n<p>Autoclaves combine heat and high pressure; OOA ovens use controlled heat and vacuum bagging, reducing cost and complexity.<\/p>\n\n\n\n<h3><strong>3. How often are Temperature Uniformity Surveys (TUS) required?<\/strong><\/h3>\n\n\n\n<p>Intervals depend on oven class and OEM spec, but audits typically require quarterly to semi-annual TUS per AMS2750.<\/p>\n\n\n\n<h3><strong>4. Why choose Despatch for NADCAP-compliant ovens?<\/strong><\/h3>\n\n\n\n<p>Despatch ovens offer engineered airflow, integrated vacuum, audit-ready controls, and global service trusted by leading aerospace OEMs.<\/p>\n\n\n\n<h3><strong>Partner with Despatch for Your Aerospace Application<\/strong><\/h3>\n\n\n\n<p>Guarantee your next NADCAP audit is a success.
